De laatste dagen zit ene zekere "filosoof" onder bijna elk van zijn postings dingen als het volgende neer te zetten :

De boodschap van "Darwin" is duidelijk: racisme en onverdraagzaamheid (normaal voor iemand die zijn pseudo zocht op een revisionnistische site...)
Kijk zelf maar hier: http://www.ety.com/HRP/race/darwin.htm
en bezoek dan ineens http://www.ety.com/HRP ook eens(waar hij die pagina vond): zegt veel over die "Darwin" hier....en over zijn bronnen en "boodschap" . Je zal vlug zien waar "Darwin" zijn mosterd haalde...
Op http://www.templeemanuelbh.com/whatisety/vind je meer info over de host ety.com..... een vreemd allegaartje, en begrijpelijk dat "Darwin" daar niet direct de lijnen van inziet
Doet dit artikeltje je niet aan de schrijfsels van "Darwin" & C° denken:http://www.ety.com/HRP/race/endoftimes.htm??

vanuit die links kan je doorsurfen naar een gans vies (en schijnbaar(!!) tegenstrijdig wereldje zoals:
http://www.carolontheweb.com/links/end.html
doet je d�*t ook niet denken aan sommige viezigheden uit extreemrechtse hoek hier? Oordeel zélf!
Ik begrijp zijn boodschap misschien beter dan hijzelf... (ik gun hem nog het voordeel van de twijfel: hij k�*n misleid zijn, gewoon de "bange blanke man"...)

In plaats van sites te raadplegen die spreken over en dingen van iemand citeren al dan niet uit de context gerukt, ga ik liever te rade bij de man en zijn volledige teksten zelf.


Op http://ibiblio.org/gutenberg/etext01/2vapd10.txt vinden we de volledige tekst en niet bewerkt of geciteerd uit de context.

Ik laat het aan jullie over om uit te maken of Darwin al dan niet een racist was. Of om het met "filosoof" te zeggen :

PELORIC FLOWERS DUE IN SOME CASES TO REVERSION.

The great principle of inheritance to be discussed in this chapter has been
recognised by agriculturists and authors of various nations, as shown by the
scientific term ATAVISM, derived from atavus, an ancestor; by the English
terms of REVERSION, or THROWING-BACK; by the French PAS-EN-ARRIERE; and by the
German RUCKSCHLAG, or RUCKSCHRITT. When the child resembles either grandparent
more closely than its immediate parents, our attention is not much arrested,
though in truth the fact is highly remarkable; but when the child resembles
some remote ancestor or some distant member in a collateral line,--and in the
last case we must attribute this to the descent of all the members from a
common progenitor,--we feel a just degree of astonishment. When one parent
alone displays some newly-acquired and generally inheritable character, and
the offspring do not inherit it, the cause may lie in the other parent having
the power of prepotent transmission. But when both parents are similarly
characterised, and the child does not, whatever the cause may be, inherit the
character in question, but resembles its grandparents, we have one of the
simplest cases of reversion. We continually see another and even more simple
case of atavism, though not generally included under this head, namely, when
the son more closely resembles his maternal than his paternal grand-sire in
some male attribute, as in any peculiarity in the beard of man, the horns of
the bull, the hackles or comb of the cock, or, as in certain diseases
necessarily confined to the male sex; for as the mother cannot possess or
exhibit such male attributes, the child must inherit them, through her blood,
from his maternal grandsire.

The cases of reversion may be divided into two main classes which, however, in
some instances, blend into one another; namely, first, those occurring in a
variety or race which has not been crossed, but has lost by variation some
character that it formerly possessed, and which afterwards reappears. The
second class includes all cases in which an individual with some
distinguishable character, a race, or species, has at some former period been
crossed, and a character derived from this cross, after having disappeared
during one or several generations, suddenly reappears. A third class,
differing only in the manner of reproduction, might be formed to include all
cases of reversion effected by means of buds, and therefore independent of
true or seminal generation. Perhaps even a fourth class might be instituted,
to include reversions by segments in the same individual flower or fruit, and
in different parts of the body in the same individual animal as it grows old.
But the two first main classes will be sufficient for our purpose.

REVERSION TO LOST CHARACTERS BY PURE OR UNCROSSED FORMS.

Striking instances of this first class of cases were given in the sixth
chapter, namely, of the occasional reappearance, in variously-coloured breeds
of the pigeon, of blue birds with all the marks characteristic of the wild
Columba livia. Similar cases were given in the case of the fowl. With the
common ass, as the legs of the wild progenitor are almost always striped, we
may feel assured that the occasional appearance of such stripes in the
domestic animal is a case of simple reversion. But I shall be compelled to
refer again to these cases, and therefore here pass them over.

The aboriginal species from which our domesticated cattle and sheep are
descended, no doubt possessed horns; but several hornless breeds are now well
established. Yet in these--for instance, in Southdown sheep--"it is not
unusual to find among the male lambs some with small horns." The horns, which
thus occasionally reappear in other polled breeds, either "grow to the full
size," or are curiously attached to the skin alone and hang "loosely down, or
drop off." (13/1. 'Youatt on Sheep' pages 20, 234. The same fact of loose
horns occasionally appearing in hornless breeds has been observed in Germany;
Bechstein 'Naturgesch. Deutschlands.' b. 1 s. 362.) The Galloways and Suffolk
cattle have been hornless for the last 100 or 150 years, but a horned calf,
with the horn often loosely attached, is occasionally produced. (13/2. 'Youatt
on Cattle' pages 155, 174.)

There is reason to believe that sheep in their early domesticated condition
were "brown or dingy black;" but even in the time of David certain flocks were
spoken of as white as snow. During the classical period the sheep of Spain are
described by several ancient authors as being black, red, or tawny. (13/3.
'Youatt on Sheep' 1838 pages 17, 145.) At the present day, notwithstanding the
great care which is taken to prevent it, particoloured lambs and some entirely
black are occasionally, or even frequently, dropped by our most highly
improved and valued breeds, such as the Southdowns. Since the time of the
famous Bakewell, during the last century, the Leicester sheep have been bred
with the most scrupulous care; yet occasionally grey-faced, or black-spotted,
or wholly black lambs appear. (13/4. I have been informed of this fact through
the Rev. W.D. Fox on the excellent authority of Mr. Wilmot: see also remarks
on this subject in an article in the 'Quarterly Review' 1849 page 395.) This
occurs still more frequently with the less improved breeds, such as the
Norfolks. (13/5. Youatt pages 19, 234.) As bearing on this tendency in sheep
to revert to dark colours, I may state (though in doing so I trench on the
reversion of crossed breeds, and likewise on the subject of prepotency) that
the Rev. W.D. Fox was informed that seven white Southdown ewes were put to a
so-called Spanish ram, which had two small black spots on his sides, and they
produced thirteen lambs, all perfectly black. Mr. Fox believes that this ram
belonged to a breed which he has himself kept, and which is always spotted
with black and white; and he finds that Leicester sheep crossed by rams of
this breed always produce black lambs: he has gone on recrossing these crossed
sheep with pure white Leicesters during three successive generations, but
always with the same result. Mr. Fox was also told by the friend from whom the
spotted breed was procured, that he likewise had gone on for six or seven
generations crossing with white sheep, but still black lambs were invariably
produced.

Similar facts could be given with respect to tailless breeds of various
animals. For instance, Mr. Hewitt (13/6. 'The Poultry Book' by Mr. Tegetmeier
1866 page 231.) states that chickens bred from some rumpless fowls, which were
reckoned so good that they won a prize at an exhibition, "in a considerable
number of instances were furnished with fully developed tail-feathers." On
inquiry, the original breeder of these fowls stated that, from the time when
he had first kept them, they had often produced fowls furnished with tails;
but that these latter would again reproduce rumpless chickens.

Analogous cases of reversion occur in the vegetable kingdom; thus "from seeds
gathered from the finest cultivated varieties of Heartsease (Viola tricolor),
plants perfectly wild both in their foliage and their flowers are frequently
produced;" (13/7. Loudon's 'Gardener's Mag.' volume 10 1834 page 396: a
nurseryman, with much experience on this subject, has likewise assured me that
this sometimes occurs.) but the reversion in this instance is not to a very
ancient period, for the best existing varieties of the heartsease are of
comparatively modern origin. With most of our cultivated vegetables there is
some tendency to reversion to what is known to be, or may be presumed to be,
their aboriginal state; and this would be more evident if gardeners did not
generally look over their beds of seedlings, and pull up the false plants or
"rogues" as they are called. It has already been remarked, that some few
seedling apples and pears generally resemble, but apparently are not identical
with, the wild trees from which they are descended. In our turnip (13/8.
'Gardener's Chronicle' 1855 page 777.) and carrot-beds a few plants often
"break "--that is, flower too soon; and their roots are generally hard and
stringy, as in the parent-species. By the aid of a little selection, carried
on during a few generations, most of our cultivated plants could probably be
brought back, without any great change in their conditions of life, to a wild
or nearly wild condition: Mr. Buckman has effected this with the parsnip
(13/9. Ibid 1862 page 721.); and Mr. Hewett C. Watson, as he informs me,
selected, during three generations, "the most diverging plants of Scotch kail,
perhaps one of the least modified varieties of the cabbage; and in the third
generation some of the plants came very close to the forms now established in
England about old castle-walls, and called indigenous."

REVERSION IN ANIMALS AND PLANTS WHICH HAVE RUN WILD.

In the cases hitherto considered, the reverting animals and plants have not
been exposed to any great or abrupt change in their conditions of life which
could have induced this tendency; but it is very different with animals and
plants which have become feral or run wild. It has been repeatedly asserted in
the most positive manner by various authors, that feral animals and plants
invariably return to their primitive specific type. It is curious on what
little evidence this belief rests. Many of our domesticated animals could not
subsist in a wild state; thus, the more highly improved breeds of the pigeon
will not "field" or search for their own food. Sheep have never become feral,
and would be destroyed by almost every beast of prey. (13/10. Mr. Boner speaks
('Chamois-hunting' 2nd edition 1860 page 92) of sheep often running wild in
the Bavarian Alps; but, on making further inquiries at my request, he found
that they are not able to establish themselves; they generally perish from the
frozen snow clinging to their wool, and they have lost the skill necessary to
pass over steep icy slopes. On one occasion two ewes survived the winter, but
their lambs perished.) In several cases we do not know the aboriginal parent-
species, and cannot possibly tell whether or not there has been any close
degree of reversion. It is not known in any instance what variety was first
turned out; several varieties have probably in some cases run wild, and their
crossing alone would tend to obliterate their proper character. Our
domesticated animals and plants, when they run wild, must always be exposed to
new conditions of life, for, as Mr. Wallace (13/11. See some excellent remarks
on this subject by Mr. Wallace 'Journal Proc. Linn. Soc.' 1858 volume 3 page
60.) has well remarked, they have to obtain their own food, and are exposed to
competition with the native productions. Under these circumstances, if our
domesticated animals did not undergo change of some kind, the result would be
quite opposed to the conclusions arrived at in this work. Nevertheless, I do
not doubt that the simple fact of animals and plants becoming feral, does
cause some tendency to reversion to the primitive state; though this tendency
has been much exaggerated by some authors.

[I will briefly run through the recorded cases. With neither horses nor cattle
is the primitive stock known; and it has been shown in former chapters that
they have assumed different colours in different countries. Thus the horses
which have run wild in South America are generally brownish-bay, and in the
East dun-coloured; their heads have become larger and coarser, and this may be
due to reversion. No careful description has been given of the feral goat.
Dogs which have run wild in various countries have hardly anywhere assumed a
uniform character; but they are probably descended from several domestic
races, and aboriginally from several distinct species. Feral cats, both in
Europe and La Plata, are regularly striped; in some cases they have grown to
an unusually large size, but do not differ from the domestic animal in any
other character. When variously-coloured tame rabbits are turned out in
Europe, they generally reacquire the colouring of the wild animal; there can
be no doubt that this does really occur, but we should remember that oddly-
coloured and conspicuous animals would suffer much from beasts of prey and
from being easily shot; this at least was the opinion of a gentleman who tried
to stock his woods with a nearly white variety; if thus destroyed, they would
be supplanted by, instead of being transformed into, the common rabbit. We
have seen that the feral rabbits of Jamaica, and especially of Porto Santo,
have assumed new colours and other new characters. The best known case of
reversion, and that on which the widely spread belief in its universality
apparently rests, is that of pigs. These animals have run wild in the West
Indies, South America, and the Falkland Islands, and have everywhere acquired
the dark colour, the thick bristles, and great tusks of the wild boar; and the
young have reacquired longitudinal stripes. But even in the case of the pig,
Roulin describes the half-wild animals in different parts of South America as
differing in several respects. In Louisiana the pig (13/12. Dureau de la Malle
'Comptes Rendus' tome 41 1855 page 807. From the statements above given, the
author concludes that the wild pigs of Louisiana are not descended from the
European Sus scrofa.) has run wild, and is said to differ a little in form,
and much in colour, from the domestic animal, yet does not closely resemble
the wild boar of Europe. With pigeons and fowls (13/13. Capt. W. Allen, in his
'Expedition to the Niger' states that fowls have run wild on the island of
Annobon, and have become modified in form and voice. The account is so meagre
and vague that it did not appear to me worth copying; but I now find that
Dureau de la Malle ('Comptes Rendus' tome 41 1855 page 690) advances this as a
good instance of reversion to the primitive stock, and as confirmatory of a
still more vague statement in classical times by Varro.), it is not known what
variety was first turned out, nor what character the feral birds have assumed.
The guinea-fowl in the West Indies, when feral, seems to vary more than in the
domesticated state.

With respect to plants run wild, Dr. Hooker (13/14. 'Flora of Australia' 1859
Introduction page 9.) has strongly insisted on what slight evidence the common
belief in their reversion to a primitive state rests. Godron (13/15. 'De
l'Espece' tome 2 pages 54, 58, 60.) describes wild turnips, carrots, and
celery; but these plants in their cultivated state hardly differ from their
wild prototypes, except in the succulency and enlargement of certain parts,--
characters which would certainly be lost by plants growing in poor soil and
struggling with other plants. No cultivated plant has run wild on so enormous
a scale as the cardoon (Cynara cardunculus) in La Plata. Every botanist who
has seen it growing there, in vast beds, as high as a horse's back, has been
struck with its peculiar appearance; but whether it differs in any important
point from the cultivated Spanish form, which is said not to be prickly like
its American descendant, or whether it differs from the wild Mediterranean
species, which is said not to be social (though this may be due merely to the
nature of the conditions), I do not know.]

REVERSION TO CHARACTERS DERIVED FROM A CROSS, IN THE CASE OF SUB-VARIETIES,
RACES, AND SPECIES.

When an individual having some recognisable peculiarity unites with another of
the same sub-variety, not having the peculiarity in question, it often
reappears in the descendants after an interval of several generations. Every
one must have noticed, or heard from old people of children closely resembling
in appearance or mental disposition, or in so small and complex a character as
expression, one of their grandparents, or some more distant collateral
relation. Very many anomalies of structure and diseases (13/16. Mr. Sedgwick
gives many instances in the 'British and Foreign Med.-Chirurg. Review' April
and July 1863 pages 448, 188.) of which instances have been given in the last
chapter, have come into a family from one parent, and have reappeared in the
progeny after passing over two or three generations. The following case has
been communicated to me on good authority, and may, I believe, be fully
trusted: a pointer-bitch produced seven puppies; four were marked with blue
and white, which is so unusual a colour with pointers that she was thought to
have played false with one of the greyhounds, and the whole litter was
condemned; but the gamekeeper was permitted to save one as a curiosity. Two
years afterwards a friend of the owner saw the young dog, and declared that he
was the image of his old pointer-bitch Sappho, the only blue and white pointer
of pure descent which he had ever seen. This led to close inquiry, and it was
proved that he was the great-great-grandson of Sappho; so that, according to
the common expression, he had only 1/16th of her blood in his veins. I may
give one other instance, on the authority of Mr. R. Walker, a large cattle-
breeder in Kincardineshire. He bought a black bull, the son of a black cow
with white legs, white belly and part of the tail white; and in 1870 a calf
the gr.-gr.-gr.-gr.-grandchild of this cow was born coloured in the same very
peculiar manner; all the intermediate offspring having been black. In these
cases there can hardly be a doubt that a character derived from a cross with
an individual of the same variety reappeared after passing over three
generations in the one case, and five in the other.

When two distinct races are crossed, it is notorious that the tendency in the
offspring to revert to one or both parent-forms is strong, and endures for
many generations. I have myself seen the clearest evidence of this in crossed
pigeons and with various plants. Mr. Sidney (13/17. In his edition of 'Youatt
on the Pig' 1860 page 27.) states that, in a litter of Essex pigs, two young
ones appeared which were the image of the Berkshire boar that had been used
twenty-eight years before in giving size and constitution to the breed. I
observed in the farmyard at Betley Hall some fowls showing a strong likeness
to the Malay breed, and was told by Mr. Tollet that he had forty years before
crossed his birds with Malays; and that, though he had at first attempted to
get rid of this strain, he had subsequently given up the attempt in despair,
as the Malay character would reappear.

This strong tendency in crossed breeds to revert has given rise to endless
discussions in how many generations after a single cross, either with a
distinct breed or merely with an inferior animal, the breed may be considered
as pure, and free from all danger of reversion. No one supposes that less than
three generations suffices, and most breeders think that six, seven, or eight
are necessary, and some go to still greater lengths. (13/18. Dr. P. Lucas,
'Hered. Nat.' tome 2 pages 314, 892: see a good practical article on the
subject in 'Gardener's Chronicle' 1856 page 620. I could add a vast number of
references, but they would be superfluous.) But neither in the case of a breed
which has been contaminated by a single cross, nor when, in the attempt to
form an intermediate breed, half-bred animals have been matched together
during many generations, can any rule be laid down how soon the tendency to
reversion will be obliterated. It depends on the difference in the strength or
prepotency of transmission in the two parent-forms, on their actual amount of
difference, and on the nature of the conditions of life to which the crossed
offspring are exposed. But we must be careful not to confound these cases of
reversion to characters which were gained by a cross, with those under the
first class, in which characters originally common to BOTH parents, but lost
at some former period, reappear; for such characters may recur after an almost
indefinite number of generations.

The law of reversion is as powerful with hybrids, when they are sufficiently
fertile to breed together, or when they are repeatedly crossed with either
pure parent-form, as in the case of mongrels. It is not necessary to give
instances. With plants almost every one who has worked on this subject, from
the time of Kolreuter to the present day, has insisted on this tendency.
Gartner has recorded some good instances; but no one has given more striking
ones than Naudin. (13/19. Kolreuter gives curious cases in his 'Dritte
Fortsetzung' 1766 ss. 53, 59; and in his well-known 'Memoirs on Lavatera and
Jalapa.' Gartner 'Bastarderzeugung' ss. 437, 441, etc. Naudin in his
"Recherches sur l'Hybridite" 'Nouvelles Archives du Museum' tome 1 page 25.)
The tendency differs in degree or strength in different groups, and partly
depends, as we shall presently see, on whether the parent-plants have been
long cultivated. Although the tendency to reversion is extremely general with
nearly all mongrels and hybrids, it cannot be considered as invariably
characteristic of them; it may also be mastered by long-continued selection;
but these subjects will more properly be discussed in a future chapter on
Crossing. From what we see of the power and scope of reversion, both in pure
races, and when varieties or species are crossed, we may infer that characters
of almost every kind are capable of reappearing after having been lost for a
great length of time. But it does not follow from this that in each particular
case certain characters will reappear; for instance, this will not occur when
a race is crossed with another endowed with prepotency of transmission.
Sometimes the power of reversion wholly fails, without our being able to
assign any cause for the failure: thus it has been stated that in a French
family in which 85 out of above 600 members, during six generations, had been
subject to night-blindness, "there has not been a single example of this
affection in the children of parents who were themselves free from it."
(13/20. Quoted by Mr. Sedgwick in 'Med.-Chirurg. Review' April 1861 page 485.
Dr. H. Dobell in 'Med.-Chirurg. Transactions' volume 46 gives an analogous
case in which, in a large family, fingers with thickened joints were
transmitted to several members during five generations; but when the blemish
once disappeared it never reappeared.)

REVERSION THROUGH BUD-PROPAGATION--PARTIAL REVERSION, BY SEGMENTS IN THE SAME
FLOWER OR FRUIT, OR IN DIFFERENT PARTS OF THE BODY IN THE SAME INDIVIDUAL
ANIMAL.

In the eleventh chapter many cases of reversion by buds, independently of
seminal generation, were given--as when a leaf-bud on a variegated, a curled,
or laciniated variety suddenly reassumes its proper character; or as when a
Provence-rose appears on a moss-rose, or a peach on a nectarine-tree. In some
of these cases only half the flower or fruit, or a smaller segment, or mere
stripes, reassume their former character; and here we have reversion by
segments. Vilmorin (13/21. Verlot 'Des Varietes' 1865 page 63.) has also
recorded several cases with plants derived from seed, of flowers reverting by
stripes or blotches to their primitive colours: he states that in all such
cases a white or pale-coloured variety must first be formed, and, when this is
propagated for a length of time by seed, striped seedlings occasionally make
their appearance; and these can afterwards by care be multiplied by seed.

The stripes and segments just referred to are not due, as far as is known, to
reversion to characters derived from a cross, but to characters lost by
variation. These cases, however, as Naudin (13/22. 'Nouvelles Archives du
Museum' tome 1 page 25. Alex. Braun (in his 'Rejuvenescence' Ray Soc. 1853
page 315) apparently holds a similar opinion.) insists in his discussion on
disjunction of character, are closely analogous with those given in the
eleventh chapter, in which crossed plants have been known to produce half-and-
half or striped flowers and fruit, or distinct kinds of flowers on the same
root resembling the two parent-forms. Many piebald animals probably come under
this same head. Such cases, as we shall see in the chapter on Crossing,
apparently result from certain characters not readily blending together, and,
as a consequence of this incapacity for fusion, the offspring either perfectly
resemble one of their two parents, or resemble one parent in one part, and the
other parent in another part; or whilst young are intermediate in character,
but with advancing age revert wholly or by segments to either parent-form, or
to both. Thus, young trees of the Cytisus adami are intermediate in foliage
and flowers between the two parent-forms; but when older the buds continually
revert either partially or wholly to both forms. The cases given in the
eleventh chapter on the changes which occurred during growth in crossed plants
of Tropaeolum, Cereus, Datura, and Lathyrus are all analogous. As, however,
these plants are hybrids of the first generation, and as their buds after a
time come to resemble their parents and not their grandparents, these cases do
not at first appear to come under the law of reversion in the ordinary sense
of the word; nevertheless, as the change is effected through a succession of
bud-generations on the same plant, they may be thus included.

Analogous facts have been observed in the animal kingdom, and are more
remarkable, as they occur in the same individual in the strictest sense, and
not as with plants through a succession of bud-generations. With animals the
act of reversion, if it can be so designated, does not pass over a true
generation, but merely over the early stages of growth in the same individual.
For instance, I crossed several white hens with a black cock, and many of the
chickens were, during the first year, perfectly white, but acquired during the
second year black feathers; on the other hand, some of the chickens which were
at first black, became during the second year piebald with white. A great
breeder (13/23. Mr. Teebay in 'The Poultry Book' by Mr. Tegetmeier 1866 page
72.) says, that a Pencilled Brahma hen which has any of the blood of the Light
Brahma in her, will "occasionally produce a pullet well pencilled during the
first year, but she will most likely moult brown on the shoulders and become
quite unlike her original colours in the second year." The same thing occurs
with light Brahmas if of impure blood. I have observed exactly similar cases
with the crossed offspring from differently coloured pigeons. But here is a
more remarkable fact: I crossed a turbit, which has a frill formed by the
feathers being reversed on its breast, with a trumpeter; and one of the young
pigeons thus raised at first showed not a trace of the frill, but, after
moulting thrice, a small yet unmistakably distinct frill appeared on its
breast. According to Girou (13/24. Quoted by Hofacker 'Ueber die
Eigenschaften' etc. s. 98.) calves produced from a red cow by a black bull, or
from a black cow by a red bull, are not rarely born red, and subsequently
become black. I possess a dog, the daughter of a white terrier by a fox-
coloured bulldog; as a puppy she was quite white, but when about six months
old a black spot appeared on her nose, and brown spots on her ears. When a
little older she was badly wounded on the back, and the hair which grew on the
cicatrix was of a brown colour, apparently derived from her father. This is
the more remarkable, as with most animals having coloured hair, that which
grows on a wounded surface is white.

In the foregoing cases, the characters which with advancing age reappeared,
were present in the immediately preceding generations; but characters
sometimes reappear in the same manner after a much longer interval of time.
Thus the calves of a hornless race of cattle which originated in Corrientes,
though at first quite hornless, as they become adult sometimes acquire small,
crooked, and loose horns; and these in succeeding years occasionally become
attached to the skull. (13/25. Azara 'Essais Hist. Nat. de Paraguay' tome 2
1801 page 372.) White and black Bantams, both of which generally breed true,
sometimes assume as they grow old a saffron or red plumage. For instance, a
first-rate black bantam has been described, which during three seasons was
perfectly black, but then annually became more and more red; and it deserves
notice that this tendency to change, whenever it occurs in a bantam, "is
almost certain to prove hereditary." (13/26. These facts are given on the high
authority of Mr. Hewitt in 'The Poultry Book' by Mr. Tegetmeier 1866 page
248.) The cuckoo or blue-mottled Dorking cock, when old, is liable to acquire
yellow or orange hackles in place of his proper bluish-grey hackles. (13/27.
'The Poultry Book' by Tegetmeier 1866 page 97.) Now as Gallus bankiva is
coloured red and orange, and as Dorking fowls and bantams are descended from
this species, we can hardly doubt that the change which occasionally occurs in
the plumage of these birds as their age advances, results from a tendency in
the individual to revert to the primitive type.

CROSSING AS A DIRECT CAUSE OF REVERSION.

It has long been notorious that hybrids and mongrels often revert to both or
to one of their parent-forms, after an interval of from two to seven or eight,
or, according to some authorities, even a greater number of generations. But
that the act of crossing in itself gives an impulse towards reversion, as
shown by the reappearance of long-lost characters, has never, I believe, been
hitherto proved. The proof lies in certain peculiarities, which do not
characterise the immediate parents, and therefore cannot have been derived
from them, frequently appearing in the offspring of two breeds when crossed,
which peculiarities never appear, or appear with extreme rarity, in these same
breeds, as long as they are precluded from crossing. As this conclusion seems
to me highly curious and novel, I will give the evidence in detail.

[My attention was first called to this subject, and I was led to make numerous
experiments, by MM. Boitard and Corbie having stated that, when they crossed
certain breeds of pigeons, birds coloured like the wild C. livia, or the
common dovecote--namely, slaty-blue, with double black wing-bars, sometimes
chequered with black, white loins, the tail barred with black, with the outer
feathers edged with white,--were almost invariably produced. The breeds which
I crossed, and the remarkable results attained, have been fully described in
the sixth chapter. I selected pigeons belonging to true and ancient breeds,
which had not a trace of blue or any of the above specified marks; but when
crossed, and their mongrels recrossed, young birds were often produced, more
or less plainly coloured slaty-blue, with some or all of the proper
characteristic marks. I may recall to the reader's memory one case, namely,
that of a pigeon, hardly distinguishable from the wild Shetland species, the
grandchild of a red-spot, white fantail, and two black barbs, from any of
which, when purely-bred, the production of a pigeon coloured like the wild C.
livia would have been almost a prodigy.

I was thus led to make the experiments, recorded in the seventh chapter, on
fowls. I selected long-established pure breeds, in which there was not a trace
of red, yet in several of the mongrels feathers of this colour appeared; and
one magnificent bird, the offspring of a black Spanish cock and white Silk
hen, was coloured almost exactly like the wild Gallus bankiva. All who know
anything of the breeding of poultry will admit that tens of thousands of pure
Spanish and of pure white Silk fowls might have been reared without the
appearance of a red feather. The fact, given on the authority of Mr.
Tegetmeier, of the frequent appearance, in mongrel fowls, of pencilled or
transversely-barred feathers, like those common to many gallinaceous birds, is
likewise apparently a case of reversion to a character formerly possessed by
some ancient progenitor of the family. I owe to the kindness of this excellent
observer the opportunity of inspecting some neck-hackles and tail-feathers
from a hybrid between the common fowl and a very distinct species, the Gallus
varius; and these feathers are transversely striped in a conspicuous manner
with dark metallic blue and grey, a character which could not have been
derived from either immediate parent.

I have been informed by Mr. B.P. Brent, that he crossed a white Aylesbury
drake and a black so-called Labrador duck, both of which are true breeds, and
he obtained a young drake closely like the mallard (A. boschas). Of the musk-
duck (Cairina moschata, Linn.) there are two sub-breeds, namely, white and
slate-coloured; and these I am informed breed true, or nearly true. But the
Rev. W.D. Fox tells me that, by putting a white drake to a slate-coloured
duck, black birds, pied with white, like the wild musk-duck, were always
produced. I hear from Mr. Blyth that hybrids from the canary and gold-finch
almost always have streaked feathers on their backs; and this streaking must
be derived from the original wild canary.

We have seen in the fourth chapter, that the so-called Himalayan rabbit, with
its snow-white body, black ears, nose, tail, and feet, breeds perfectly true.
This race is known to have been formed by the union of two varieties of
silver-grey rabbits. Now, when a Himalayan doe was crossed by a sandy-coloured
buck, a silver-grey rabbit was produced; and this is evidently a case of
reversion to one of the parent varieties. The young of the Himalayan rabbit
are born snow-white, and the dark marks do not appear until some time
subsequently; but occasionally young Himalayan rabbits are born of a light
silver-grey, which colour soon disappears; so that here we have a trace of
reversion, during an early period of life, to the parent varieties,
independently of any recent cross.

In the third chapter it was shown that at an ancient period some breeds of
cattle in the wilder parts of Britain were white with dark ears, and that the
cattle now kept half wild in certain parks, and those which have run quite
wild in two distant parts of the world, are likewise thus coloured. Now, an
experienced breeder, Mr. J. Beasley, of Northamptonshire (13/28. 'Gardener's
Chronicle and Agricultural Gazette' 1866 page 528.), crossed some carefully
selected West Highland cows with purely-bred shorthorn bulls. The bulls were
red, red and white, or dark roan; and the Highland cows were all of a red
colour, inclining to a light or yellow shade. But a considerable number of the
offspring--and Mr. Beasley calls attention to this as a remarkable fact--were
white, or white with red ears. Bearing in mind that none of the parents were
white, and that they were purely-bred animals, it is highly probable that here
the offspring reverted, in consequence of the cross, to the colour of some
ancient and half-wild parent-breed. The following case, perhaps, comes under
the same head: cows in their natural state have their udders but little
developed, and do not yield nearly so much milk as our domesticated animals.
Now there is some reason to believe (13/29. Ibid 1860 page 343. I am glad to
find that so experienced a breeder of cattle as Mr. Willoughby Wood,
'Gardener's Chronicle' 1869 page 1216, admits my principle of a cross giving a
tendency to reversion.) that cross-bred animals between two kinds, both of
which are good milkers, such as Alderneys and Shorthorns, often turn out
worthless in this respect.

In the chapter on the Horse reasons were assigned for believing that the
primitive stock was striped and dun-coloured; and details were given, showing
that in all parts of the world stripes of a dark colour frequently appear
along the spine, across the legs, and on the shoulders, where they are
occasionally double or treble, and even sometimes on the face and body of
horses of all breeds and of all colours. But the stripes appear most
frequently on the various kinds of duns. In foals they are sometimes plainly
seen, and subsequently disappear. The dun-colour and the stripes are strongly
transmitted when a horse thus characterised is crossed with any other; but I
was not able to prove that striped duns are generally produced from the
crossing of two distinct breeds, neither of which are duns, though this does
sometimes occur.

The legs of the ass are often striped, and this may be considered as a
reversion to the wild parent form, the Equus taeniopus of Abyssinia (13/30.
Sclater in 'Proc. Zoolog. Soc.' 1862 page 163.), which is generally thus
striped. In the domestic animal the stripes on the shoulder are occasionally
double, or forked at the extremity, as in certain zebrine species. There is
reason to believe that the foal is more frequently striped on the legs than
the adult animal. As with the horse, I have not acquired any distinct evidence
that the crossing of differently-coloured varieties of the ass brings out the
stripes.

But now let us turn to the result of crossing the horse and ass. Although
mules are not nearly so numerous in England as asses, I have seen a much
greater number with striped legs, and with the stripes far more conspicuous
than in either parent-form. Such mules are generally light-coloured, and might
be called fallow-duns. The shoulder-stripe in one instance was deeply forked
at the extremity, and in another instance was double, though united in the
middle. Mr. Martin gives a figure of a Spanish mule with strong zebra-like
marks on its legs (13/31. 'History of the Horse' page 212.), and remarks that
mules are particularly liable to be thus striped on their legs. In South
America, according to Roulin (13/32. 'Mem. presentes par divers Savans a
l'Acad. Royale' tome 6 1835 page 338.), such stripes are more frequent and
conspicuous in the mule than in the ass. In the United States, Mr. Gosse
(13/33. 'Letters from Alabama' 1859 page 280.), speaking of these animals,
says, "that in a great number, perhaps in nine out of every ten, the legs are
banded with transverse dark stripes."

Many years ago I saw in the Zoological Gardens a curious triple hybrid, from a
bay mare, by a hybrid from a male ass and female zebra. This animal when old
had hardly any stripes; but I was assured by the superintendent, that when
young it had shoulder-stripes, and faint stripes on its flanks and legs. I
mention this case more especially as an instance of the stripes being much
plainer during youth than in old age.

As the zebra has such a conspicuously striped body and legs, it might have
been expected that the hybrids from this animal and the common ass would have
had their legs in some degree striped; but it appears from the figures given
in Dr. Gray's 'Knowsley Gleanings' and still more plainly from that given by
Geoffroy and F. Cuvier (13/34. 'Hist. Nat. des Mammiferes' 1820 tome 1), that
the legs are much more conspicuously striped than the rest of the body; and
this fact is intelligible only on the belief that the ass aids in giving,
through the power of reversion, this character to its hybrid offspring.

The quagga is banded over the whole front part of its body like a zebra, but
has no stripes on its legs, or mere traces of them. But in the famous hybrid
bred by Lord Morton (13/35. 'Philosoph. Transact.' 1821 page 20.) from a
chestnut, nearly purely-bred, Arabian mare, by a male quagga, the stripes were
"more strongly defined and darker than those on the legs of "the quagga." The
mare was subsequently put to a black Arabian horse, and bore two colts, both
of which, as formerly stated, were plainly striped on the legs, and one of
them likewise had stripes on the neck and body.

The Equus indicus (13/36. Sclater in 'Proc. Zoolog. Soc.' 1862 page 163: this
species is the Ghor-Khur of N.W. India, and has often been called the Hemionus
of Pallas. See also Mr. Blyth's excellent paper in 'Journal of Asiatic Soc. of
Bengal' volume 28 1860 page 229.) is characterised by a spinal stripe, without
shoulder or leg stripes; but traces of these latter stripes may occasionally
be seen even in the adult (13/37. Another species of wild ass, the true E.
hemionus or Kiang, which ordinarily has no shoulder-stripes, is said
occasionally to have them; and these, as with the horse and ass, are sometimes
double: see Mr. Blyth in the paper just quoted and in 'Indian Sporting Review'
1856 page 320: and Col. Hamilton Smith in 'Nat. Library, Horses' page 318; and
'Dict. Class. d'Hist. Nat.' tome 3 page 563.) and Colonel S. Poole, who has
had ample opportunities for observation, informs me that in the foal, when
first born, the head and legs are often striped, but the shoulder-stripe is
not so distinct as in the domestic ass; all these stripes, excepting that
along the spine, soon disappear. Now a hybrid, raised at Knowsley (13/38.
Figured in the 'Gleanings from the Knowsley Menageries' by Dr. J.E. Gray.)
from a female of this species by a male domestic ass, had all four legs
transversely and conspicuously striped, had three short stripes on each
shoulder and had even some zebra-like stripes on its face! Dr. Gray informs me
that he has seen a second hybrid of the same parentage, similarly striped.

From these facts we see that the crossing of the several equine species tends
in a marked manner to cause stripes to appear on various parts of the body,
especially on the legs. As we do not know whether the parent-form of the genus
was striped, the appearance of the stripes can only hypothetically be
attributed to reversion. But most persons, after considering the many
undoubted cases of variously coloured marks reappearing by reversion in my
experiments on crossed pigeons and fowls, will come to the same conclusion
with respect to the horse-genus; and if so, we must admit that the progenitor
of the group was striped on the legs, shoulders, face, and probably over the
whole body, like a zebra.

Lastly, Professor Jaeger has given (13/39. 'Darwin'sche Theorie und ihre
Stellung zu Moral und Religion' page 85.) a good case with pigs. He crossed
the Japanese or masked breed with the common German breed, and the offspring
were intermediate in character. He then re-crossed one of these mongrels with
the pure Japanese, and in the litter thus produced one of the young resembled
in all its characters a wild pig; it had a long snout and upright ears, and
was striped on the back. It should be borne in mind that the young of the
Japanese breed are not striped, and that they have a short muzzle and ears
remarkably dependent.]

A similar tendency to the recovery of long lost characters holds good even
with the instincts of crossed animals. There are some breeds of fowls which
are called "everlasting layers," because they have lost the instinct of
incubation; and so rare is it for them to incubate that I have seen notices
published in works on poultry, when hens of such breeds have taken to sit.
(13/40. Cases of both Spanish and Polish hens sitting are given in the
'Poultry Chronicle' 1855 volume 3 page 477.) Yet the aboriginal species was of
course a good incubator; and with birds in a state of nature hardly any
instinct is so strong as this. Now, so many cases have been recorded of the
crossed offspring from two races, neither of which are incubators, becoming
first-rate sitters, that the reappearance of this instinct must be attributed
to reversion from crossing. One author goes so far as to say, "that a cross
between two non-sitting varieties almost invariably produces a mongrel that
becomes broody, and sits with remarkable steadiness." (13/41. 'The Poultry
Book' by Mr. Tegetmeier 1866 pages 119, 163. The author, who remarks on the
two negatives ('Journ. of Hort.' 1862 page 325), states that two broods were
raised from a Spanish cock and Silver-pencilled Hamburgh hen, neither of which
are incubators, and no less than seven out of eight hens in these two broods
"showed a perfect obstinacy in sitting." The Rev. E.S. Dixon ('Ornamental
Poultry' 1848 page 200) says that chickens reared from a cross between Golden
and Black Polish fowls, are "good and steady birds to sit." Mr. B.P. Brent
informs me that he raised some good sitting hens by crossing Pencilled
Hamburgh and Polish breeds. A cross-bred bird from a Spanish non-incubating
cock and Cochin incubating hen is mentioned in the 'Poultry Chronicle' volume
3 page 13, as an "exemplary mother." On the other hand, an exceptional case is
given in the 'Cottage Gardener' 1860 page 388 of a hen raised from a Spanish
cock and black Polish hen which did not incubate.) Another author, after
giving a striking example, remarks that the fact can be explained only on the
principle that "two negatives make a positive." It cannot, however, be
maintained that hens produced from a cross between two non-sitting breeds
invariably recover their lost instinct, any more than that crossed fowls or
pigeons invariably recover the red or blue plumage of their prototypes. Thus I
raised several chickens from a Polish hen by a Spanish cock,--breeds which do
not incubate,--and none of the young hens at first showed any tendency to sit;
but one of them--the only one which was preserved--in the third year sat well
on her eggs and reared a brood of chickens. So that here we have the
reappearance with advancing age of a primitive instinct, in the same manner as
we have seen that the red plumage of the Gallus bankiva is sometimes
reacquired both by crossed and purely-bred fowls of various kinds as they grow
old.

The parents of all our domesticated animals were of course aboriginally wild
in disposition; and when a domesticated species is crossed with a distinct
species, whether this is a domesticated or only a tamed animal, the hybrids
are often wild to such a degree, that the fact is intelligible only on the
principle that the cross has caused a partial return to a primitive
disposition. Thus, the Earl of Powis formerly imported some thoroughly
domesticated humped cattle from India, and crossed them with English breeds,
which belong to a distinct species; and his agent remarked to me, without any
question having been asked, how oddly wild the cross-bred animals were. The
European wild boar and the Chinese domesticated pig are almost certainly
specifically distinct: Sir F. Darwin crossed a sow of the latter breed with a
wild Alpine boar which had become extremely tame, but the young, though having
half-domesticated blood in their veins, were "extremely wild in confinement,
and would not eat swill like common English pigs." Captain Hutton, in India,
crossed a tame goat with a wild one from the Himalaya, and he remarked to me
how surprisingly wild the offspring were. Mr. Hewitt, who has had great
experience in crossing tame cock-pheasants with fowls belonging to five
breeds, gives as the character of all "extraordinary wildness" (13/42. 'The
Poultry Book' by Tegetmeier 1866 pages 165, 167.); but I have myself seen one
exception to this rule. Mr. S. J. Salter (13/43. 'Natural History Review' 1863
April page 277.) who raised a large number of hybrids from a bantam-hen by
Gallus sonneratii, states that "all were exceedingly wild." Mr. Waterton
(13/44. 'Essays on Natural History' page 917.) bred some wild ducks from eggs
hatched under a common duck, and the young were allowed to cross freely both
amongst themselves and with the tame ducks; they were "half wild and half
tame; they came to the windows to be fed, but still they had a wariness about
them quite remarkable."

On the other hand, mules from the horse and ass are certainly not in the least
wild, though notorious for obstinacy and vice. Mr. Brent, who has crossed
canary-birds with many kinds of finches, has not observed, as he informs me,
that the hybrids were in any way remarkably wild: but Mr. Jenner Weir who has
had still greater experience, is of a directly opposite opinion. He remarks
that the siskin is the tamest of finches, but its mules are as wild, when
young, as newly caught birds, and are often lost through their continued
efforts to escape. Hybrids are often raised between the common and musk duck,
and I have been assured by three persons, who have kept these crossed birds,
that they were not wild; but Mr. Garnett (13/45. As stated by Mr. Orton in his
'Physiology of Breeding' page 12.) observed that his hybrids were wild, and
exhibited "migratory propensities" of which there is not a vestige in the
common or musk duck. No case is known of this latter bird having escaped and
become wild in Europe or Asia, except, according to Pallas, on the Caspian
Sea; and the common domestic duck only occasionally becomes wild in districts
where large lakes and fens abound. Nevertheless, a large number of cases have
been recorded (13/46. M. E. de Selys-Longchamps refers ('Bulletin Acad. Roy.
de Bruxelles' tome 12 No. 10) to more than seven of these hybrids shot in
Switzerland and France. M. Deby asserts ('Zoologist' volume 5 1845-46 page
1254) that several have been shot in various parts of Belgium and Northern
France. Audubon ('Ornitholog. Biography' volume 3 page 168), speaking of these
hybrids, says that, in North America, they "now and then wander off and become
quite wild.") of hybrids from these two ducks having been shot in a completely
wild state, although so few are reared in comparison with purely-bred birds of
either species. It is improbable that any of these hybrids could have acquired
their wildness from the musk-duck having paired with a truly wild duck; and
this is known not to be the case in North America; hence we must infer that
they have reacquired, through reversion, their wildness, as well as renewed
powers of flight.

These latter facts remind us of the statements, so frequently made by
travellers in all parts of the world, on the degraded state and savage
disposition of crossed races of man. That many excellent and kind-hearted
mulattos have existed no one will dispute; and a more mild and gentle set of
men could hardly be found than the inhabitants of the island of Chiloe, who
consist of Indians commingled with Spaniards in various proportions. On the
other hand, many years ago, long before I had thought of the present subject,
I was struck with the fact that, in South America, men of complicated descent
between Negroes, Indians, and Spaniards, seldom had, whatever the cause might
be, a good expression. (13/47. 'Journal of Researches' 1845 page 71.)
Livingstone--and a more unimpeachable authority cannot be quoted,--after
speaking of a half-caste man on the Zambesi, described by the Portuguese as a
rare monster of inhumanity, remarks, "It is unaccountable why half-castes,
such as he, are so much more cruel than the Portuguese, but such is
undoubtedly the case." An inhabitant remarked to Livingstone, "God made white
men, and God made black men, but the Devil made halfcastes." (13/48.
'Expedition to the Zambesi' 1865 pages 25, 150.) When two races, both low in
the scale, are crossed the progeny seems to be eminently bad. Thus the noble-
hearted Humboldt, who felt no prejudice against the inferior races, speaks in
strong terms of the bad and savage disposition of Zambos, or half-castes
between Indians and Negroes; and this conclusion has been arrived at by
various observers. (13/49. Dr. P. Broca on 'Hybridity in the Genus Homo'
English translation 1864 page 39.) From these facts we may perhaps infer that
the degraded state of so many half-castes is in part due to reversion to a
primitive and savage condition, induced by the act of crossing, even if mainly
due to the unfavourable moral conditions under which they are generally
reared.

SUMMARY ON THE PROXIMATE CAUSES LEADING TO REVERSION.

When purely-bred animals or plants reassume long-lost characters,--when the
common ass, for instance, is born with striped legs, when a pure race of black
or white pigeons throws a slaty-blue bird, or when a cultivated heartsease
with large and rounded flowers produces a seedling with small and elongated
flowers,--we are quite unable to assign any proximate cause. When animals run
wild, the tendency to reversion, which, though it has been greatly
exaggerated, no doubt exists, is sometimes to a certain extent intelligible.
Thus, with feral pigs, exposure to the weather will probably favour the growth
of the bristles, as is known to be the case with the hair of other
domesticated animals, and through correlation the tusks will tend to be
redeveloped. But the reappearance of coloured longitudinal stripes on young
feral pigs cannot be attributed to the direct action of external conditions.
In this case, and in many others, we can only say that any change in the
habits of life apparently favour a tendency, inherent or latent in the
species, to return to the primitive state.

It will be shown in a future chapter that the position of flowers on the
summit of the axis, and the position of seeds within the capsule, sometimes
determine a tendency towards reversion; and this apparently depends on the
amount of sap or nutriment which the flower-buds and seeds receive. The
position, also, of buds, either on branches or on roots, sometimes determines,
as was formerly shown, the transmission of the character proper to the
variety, or its reversion to a former state.

We have seen in the last section that when two races or species are crossed
there is the strongest tendency to the reappearance in the offspring of long-
lost characters, possessed by neither parent nor immediate progenitor. When
two white, or red, or black pigeons, of well-established breeds, are united,
the offspring are almost sure to inherit the same colours; but when
differently-coloured birds are crossed, the opposed forces of inheritance
apparently counteract each other, and the tendency which is inherent in both
parents to produce slaty-blue offspring becomes predominant. So it is in
several other cases. But when, for instance, the ass is crossed with E.
indicus or with the horse--animals which have not striped legs--and the
hybrids have conspicuous stripes on their legs and even on their faces, all
that can be said is, that an inherent tendency to reversion is evolved through
some disturbance in the organisation caused by the act of crossing.

Another form of reversion is far commoner, indeed is almost universal with the
offspring from a cross, namely, to the characters proper to either pure
parent-form. As a general rule, crossed offspring in the first generation are
nearly intermediate between their parents, but the grandchildren and
succeeding generations continually revert, in a greater or lesser degree, to
one or both of their progenitors. Several authors have maintained that hybrids
and mongrels include all the characters of both parents, not fused together,
but merely mingled in different proportions in different parts of the body;
or, as Naudin (13/50. 'Nouvelles Archives du Museum' tome 1 page 151.) has
expressed it, a hybrid is a living mosaic-work, in which the eye cannot
distinguish the discordant elements, so completely are they intermingled. We
can hardly doubt that, in a certain sense, this is true, as when we behold in
a hybrid the elements of both species segregating themselves into segments in
the same flower or fruit, by a process of self-attraction or self-affinity;
this segregation taking place either by seminal or bud-propagation. Naudin
further believes that the segregation of the two specific elements or essences
is eminently liable to occur in the male and female reproductive matter; and
he thus explains the almost universal tendency to reversion in successive
hybrid generations. For this would be the natural result of the union of
pollen and ovules, in both of which the elements of the same species had been
segregated by self-affinity. If, on the other hand, pollen which included the
elements of one species happened to unite with ovules including the elements
of the other species, the intermediate or hybrid state would still be
retained, and there would be no reversion. But it would, as I suspect, be more
correct to say that the elements of both parent-species exist in every hybrid
in a double state, namely, blended together and completely separate. How this
is possible, and what the term specific essence or element may be supposed to
express, I shall attempt to show in the chapter on the hypothesis of
pangenesis.

But Naudin's view, as propounded by him, is not applicable to the reappearance
of characters lost long ago by variation; and it is hardly applicable to races
or species which, after having been crossed at some former period with a
distinct form, and having since lost all traces of the cross, nevertheless
occasionally yield an individual which reverts (as in the case of the great-
great-grandchild of the pointer Sappho) to the crossing form. The most simple
case of reversion, namely, of a hybrid or mongrel to its grandparents, is
connected by an almost perfect series with the extreme case of a purely-bred
race recovering characters which had been lost during many ages; and we are
thus led to infer that all the cases must be related by some common bond.

Gartner believed that only highly sterile hybrid plants exhibit any tendency
to reversion to their parent-forms. This erroneous belief may perhaps be
accounted for by the nature of the genera crossed by him, for he admits that
the tendency differs in different genera. The statement is also directly
contradicted by Naudin's observations, and by the notorious fact that
perfectly fertile mongrels exhibit the tendency in a high degree,--even in a
higher degree, according to Gartner himself, than hybrids. (13/51.
'Bastarderzeugung' s. 582, 438, etc.)

Gartner further states that reversions rarely occur with hybrid plants raised
from species which have not been cultivated, whilst, with those which have
been long cultivated, they are of frequent occurrence. This conclusion
explains a curious discrepancy: Max Wichura (13/52. 'Die Bastardbefruchtung...
der Weiden' 1865 s. 23. For Gartner's remarks on this head, see
'Bastarderzeugung' s. 474, 582.) who worked exclusively on willows which had
not been subjected to culture, never saw an instance of reversion; and he goes
so far as to suspect that the careful Gartner had not sufficiently protected
his hybrids from the pollen of the parent-species: Naudin, on the other hand,
who chiefly experimented on cucurbitaceous and other cultivated plants,
insists more strenuously than any other author on the tendency to reversion in
all hybrids. The conclusion that the condition of the parent-species, as
affected by culture, is one of the proximate causes leading to reversion,
agrees well with the converse case of domesticated animals and cultivated
plants being liable to reversion when they become feral; for in both cases the
organisation or constitution must be disturbed, though in a very different
way. (13/53. Prof. Weismann in his very curious essay on the different forms
produced by the same species of butterfly at different seasons ('Saison-
Dimorphismus der Schmetterlinge' pages 27, 28), has come to a similar
conclusion, namely, that any cause which disturbs the organisation, such as
the exposure of the cocoons to heat or even to much shaking, gives a tendency
to reversion.)

Finally, we have seen that characters often reappear in purely-bred races
without our being able to assign any proximate cause; but when they become
feral this is either indirectly or directly induced by the change in their
conditions of life. With crossed breeds, the act of crossing in itself
certainly leads to the recovery of long-lost characters, as well as of those
derived from either parent-form. Changed conditions, consequent on
cultivation, and the relative position of buds, flowers, and seeds on the
plant, all apparently aid in giving this same tendency. Reversion may occur
either through seminal or bud generation, generally at birth, but sometimes
only with an advance of age. Segments or portions of the individual may alone
be thus affected. That a being should be born resembling in certain characters
an ancestor removed by two or three, and in some cases by hundreds or even
thousands of generations, is assuredly a wonderful fact. In these cases the
child is commonly said to inherit such characters directly from its
grandparent, or more remote ancestors. But this view is hardly conceivable.
If, however, we suppose that every character is derived exclusively from the
father or mother, but that many characters lie latent or dormant in both
parents during a long succession of generations, the foregoing facts are
intelligible. In what manner characters may be conceived to lie latent, will
be considered in a future chapter to which I have lately alluded.

LATENT CHARACTERS.

But I must explain what is meant by characters lying latent. The most obvious
illustration is afforded by secondary sexual characters. In every female all
the secondary male characters, and in every male all the secondary female
characters, apparently exist in a latent state, ready to be evolved under
certain conditions. It is well known that a large number of female birds, such
as fowls, various pheasants, partridges, peahens, ducks, etc., when old or
diseased, or when operated on, assume many or all of the secondary male
characters of their species. In the case of the hen-pheasant this has been
observed to occur far more frequently during certain years than during others.

Weet je nog wat het grappigste is? Als de echte Darwin nog geleefd zou hebben, zou hij onmiddellijk gepleit hebben voor het kruisen met zwarten !! Liefst zoveel mogelijk, gezien de absolute lichamelijke superioriteit van de zwarten. Zij zijn over het algemeen gezonder, atletischer en kunnen meer verdragen.

Een ander punt dat vele reversionisten vergeten, is dat er nog zoiets bestaat als "inbreeding" en "genetic drift", ofwel inteelt en genetische drift, waarmee bedoeld wordt dat als je steeds in dezelfde genenpool blijft, de genetische variatie kleiner wordt, en bepaalde vormen van een aantal genen gewoon gaan verdwijnen. En deze verminderde variatie vormt een bedreiging voor de soort, gezien de overleving van een soort juist gebaseerd is op haar capaciteit om wisselende omstandigheden op te vangen door variatie binnen de soort. D�*t is het principe van natuurlijke selectie en de overleving van de meest aangepaste.

Dus Darwin de nepper, leer eens wat uw grote voorbeeld U verteld heeft, en STOP met die nonsens. Darwin is een argument PRO rassenvermenging, niet contra. Of wil jij ook van die dikbilrundertoestanden? Je vergeet dat al die soorten die je aanhaalt, boerderijdieren zijn die in het wild niet meer kunnen overleven, en dikwijls hypergevoelig zijn aan stress en allerlei afwijkingen hebben. Maar wél een goede vleesproductie...

Toen het 70-punten programma hier gepost werd, incluis de terugkeer van ALLE migranten van de tweede en derde generatie, was zijn reactie:

"Na lezing van hoofdstuk IX "de terugkeer organiseren", moet ik me inderdaad inhouden om niet onmiddellijk een lidmaatschap van het Vlaams Blok aan te vragen. "

Politiek correcten schijnen nogal eens te vergeten dat het iedereens goede recht is om 'racist' te zijn.
Het enige dat bij wet verboden is: aanzetten van anderen tot daden op racisme geïnspireerd.
Of het nu een hoogstaande levensvisie is of niet, doet er niet toe.
Of racisme ethisch verdedigbaar is, doet er niet toe.

Laat gewoon elke racist zijn zegje doen.
Als hij al met argumenten voor de pinnen komt, dan kan je hem er rustig met sterkere argumenten op wijzen dat hij ernaast zit.
Dit biedt het voordeel dat dergelijke meningen niet tot sluipend ondergronds gif kunnen verworden. Iedereen mag weten uit welke hoek de wind waait.
Geef eenieder de kans zijn mening openlijk belijden. Dan pas kan er geargumenteerd worden.

Tuurlijk. het is evengoed mijn goed recht om aan te halen dat Darwin (de echte dan) absoluut géén argument is tegen rassenvermenging, wel integendeel. En het is nog veel meer mijn recht om hun ganse redenering stupide te vinden, en er ook voor uit te komen. Ze mogen gerust hun zegje doen, ik doe het mijne ook.

Ik had het over de reportage over ENGELSE (niet VS) neo-nazi's. En ik had het over rassenvermenging, die dikbilrunderen was maar een voorbeeld van inteelt. Kwestie van de "zuiverheid van het blanke ras" niet te hoog in te schatten, gezien onze mindere fysische gezondheid (genetisch trouwens ! )

Ik had het niet over een bevolkingsgroep, ik had het over een ideologie. En er lopen inderdaad wel meer zotten op de wereld. Met dat verschil dat een aantal zotten niet op ras selecteren, maar op godsdienst. En tot een godsdienst kan je je bekeren, tot een ras niet. Gevaar voor inteelt is er dus een heel pak minder, bewijze de bekeerde belgische moslims.

Of had je het nu over de joodse gemeenschap in Antwerpen?

Ik denk inderdaad dat de consistente gewoonte om inteelt te bedrijven, al of niet in opdracht van een of andere hogere macht, gevaarlijker en zeker nadeliger is dan een doelbewust kiezen op kleurtjes.

Het is U tenandere waarschijnlijk toch niet onbekend dat er bijna geen genetische variatie zit tussen de verschillende etnische groepen? Daarom heeft men ook besloten dat men zeker niet kan praten van verschillende mensenRASSEN!

Een van de conclusies die men kon trekken was dat er meer genetische diversiteit bestond binnen de afrikaanse etnische groepen, dan binnen andere etnieën, waaruit men kon besluiten dat de afrikaanse groep veel ouder is dan dan andere etnische groepen.
Een andere conclusie was dat de Indiaanse stammen allen één specifiek gen gemeen hadden, wat erop wees dat ze in feite werkelijk van één bepaalde stamvader afstammen! Die zijn er dus tenminste zeker van!

Een vermenging van verschillende "rassen" hoeft daarom niet noodzakelijk een meerwaarde te betekenen. vb. vooral bij blanken kan huidkanker voorkomen, niet bij zwarten.
Een van de beroemste halfbloeden (en laat me nu toch zijn naam kwijtspelen die van de reggae muziek) is echter TOCH overleden aan huidkanker (van zijne pa overgeërfd!)

groetjes en prettig week-end.

Wrong. Kleur is genetisch bepaald en kiezen op kleur zorgt voor genetische drift. Kiezen uit een voldoende genetisch heterogene groep is voor de overleving van een soort fundamenteel belangrijk.

Citaat:

Wrong again. Dat rassen een onbruikbare term is, ligt gewoon aan het feit dat het begrip "ras" een arbitraire indeling inhoudt, terwijl het begrip "soort" een zeer duidelijke omschrijving heeft (ingeval van seksuele reproductie, bij bacteriën en parthenogenetische organismen ligt dat iets moeilijker) : twee leden zijn van eenzelfde soort als ze onderling kunnen kruisen en VRUCHTBARE nakomelingen voortbrengen.

Er zit inderdaad héél weinig genetische variatie bij de mens, maar dat is zo bij ELKE soort. En toch is inteelt en zeker "genetic drift" zeer goed mogelijk. De weinige genetische variatie tussen rassen is juist afkomstig van het mengen. Als die niet meer mengen, dan drijven hun genpatronen uit elkaar tot het punt waar reproductie niet meer mogelijk is. En dan heb je twee nieuwe soorten, als de beginpopulaties groot genoeg waren.

Citaat:

99% van de DNA-sequentie bij mensen is identiek. Mooi, we stammen allemaal af van dezelfde adam. Dat weten we dan ook weeral

huidkanker kan evengoed bij zwarten voorkomen. Het zijn wel enkel zwarten die resistentie ontwikkeld hebben tegen malaria, toevallig net omdat het gen voor hemoglobinevorming beschadigd was. Maf verhaal dus.

Soit, er zijn geen zinnige argumenten te vinden voor rassenscheiding, dat is nu eenmaal een feit. Ik negeer in dit verhaal ook een factor, scheiding van rassen is eigenlijk ook niet zo'n probleem. Aan U om aan te duiden wat ik vergeten ben.

Ik dacht dat rassen niet bestonden. Dat het enige verschil tussen mensen onderling de kleur is.
Volgens deskundigen bestaan er hondenrassen, kattenrassen, duivenrassen, koeienrassen, paardenrassen, schapenrassen ...

Er bestaan volgens deze deskundigen echter geen mensenrassen ...


Op de revisionistische site waar filosoof naar verwijst staan een aantal paragrafen geplukt uit "The Variation of Animals and Plants under Domestication Volume 2" van Charles Darwin, onder meer de laatste van de volgende drie paragrafen (cursief) :



The parents of all our domesticated animals were of course aboriginally wild in disposition; and when a domesticated species is crossed with a distinct species, whether this is a domesticated or only a tamed animal, the hybrids are often wild to such a degree, that the fact is intelligible only on the principle that the cross has caused a partial return to a primitive disposition. Thus, the Earl of Powis formerly imported some thoroughly domesticated humped cattle from India, and crossed them with English breeds, which belong to a distinct species; and his agent remarked to me, without any question having been asked, how oddly wild the cross-bred animals were. The European wild boar and the Chinese domesticated pig are almost certainly specifically distinct: Sir F. Darwin crossed a sow of the latter breed with a wild Alpine boar which had become extremely tame, but the young, though having half-domesticated blood in their veins, were "extremely wild in confinement, and would not eat swill like common English pigs." Captain Hutton, in India, crossed a tame goat with a wild one from the Himalaya, and he remarked to me how surprisingly wild the offspring were. Mr. Hewitt, who has had great experience in crossing tame cock-pheasants with fowls belonging to five breeds, gives as the character of all "extraordinary wildness" (13/42. 'The Poultry Book' by Tegetmeier 1866 pages 165, 167.); but I have myself seen one exception to this rule. Mr. S. J. Salter (13/43. 'Natural History Review' 1863 April page 277.) who raised a large number of hybrids from a bantam-hen by Gallus sonneratii, states that "all were exceedingly wild." Mr. Waterton (13/44. 'Essays on Natural History' page 917.) bred some wild ducks from eggs hatched under a common duck, and the young were allowed to cross freely both amongst themselves and with the tame ducks; they were "half wild and half tame; they came to the windows to be fed, but still they had a wariness about them quite remarkable."

On the other hand, mules from the horse and ass are certainly not in the least wild, though notorious for obstinacy and vice. Mr. Brent, who has crossed canary-birds with many kinds of finches, has not observed, as he informs me, that the hybrids were in any way remarkably wild: but Mr. Jenner Weir who has had still greater experience, is of a directly opposite opinion. He remarks that the siskin is the tamest of finches, but its mules are as wild, when young, as newly caught birds, and are often lost through their continued efforts to escape. Hybrids are often raised between the common and musk duck, and I have been assured by three persons, who have kept these crossed birds, that they were not wild; but Mr. Garnett (13/45. As stated by Mr. Orton in his 'Physiology of Breeding' page 12.) observed that his hybrids were wild, and exhibited "migratory propensities" of which there is not a vestige in the common or musk duck. No case is known of this latter bird having escaped and become wild in Europe or Asia, except, according to Pallas, on the Caspian Sea; and the common domestic duck only occasionally becomes wild in districts where large lakes and fens abound. Nevertheless, a large number of cases have been recorded (13/46. M. E. de Selys-Longchamps refers ('Bulletin Acad. Roy. de Bruxelles' tome 12 No. 10) to more than seven of these hybrids shot in Switzerland and France. M. Deby asserts ('Zoologist' volume 5 1845-46 page 1254) that several have been shot in various parts of Belgium and Northern France. Audubon ('Ornitholog. Biography' volume 3 page 168), speaking of these hybrids, says that, in North America, they "now and then wander off and become quite wild.") of hybrids from these two ducks having been shot in a completely wild state, although so few are reared in comparison with purely-bred birds of either species. It is improbable that any of these hybrids could have acquired their wildness from the musk-duck having paired with a truly wild duck; and this is known not to be the case in North America; hence we must infer that they have reacquired, through reversion, their wildness, as well as renewed powers of flight.

These latter facts remind us of the statements, so frequently made by travellers in all parts of the world, on the degraded state and savage disposition of crossed races of man. That many excellent and kind-hearted mulattos have existed no one will dispute; and a more mild and gentle set of men could hardly be found than the inhabitants of the island of Chiloe, who consist of Indians commingled with Spaniards in various proportions. On the other hand, many years ago, long before I had thought of the present subject, I was struck with the fact that, in South America, men of complicated descent between Negroes, Indians, and Spaniards, seldom had, whatever the cause might be, a good expression. (13/47. 'Journal of Researches' 1845 page 71.) Livingstone--and a more unimpeachable authority cannot be quoted,--after speaking of a half-caste man on the Zambesi, described by the Portuguese as a rare monster of inhumanity, remarks, "It is unaccountable why half-castes, such as he, are so much more cruel than the Portuguese, but such is undoubtedly the case." An inhabitant remarked to Livingstone, "God made white men, and God made black men, but the Devil made halfcastes." (13/48. 'Expedition to the Zambesi' 1865 pages 25, 150.) When two races, both low in the scale, are crossed the progeny seems to be eminently bad. Thus the noble-hearted Humboldt, who felt no prejudice against the inferior races, speaks in strong terms of the bad and savage disposition of Zambos, or half-castes between Indians and Negroes; and this conclusion has been arrived at by various observers. (13/49. Dr. P. Broca on 'Hybridity in the Genus Homo' English translation 1864 page 39.) From these facts we may perhaps infer that the degraded state of so many half-castes is in part due to reversion to a primitive and savage condition, induced by the act of crossing, even if mainly due to the unfavourable moral conditions under which they are generally reared.




We moeten van Charles Darwin dus zeker geen heilige maken.


Wat filosoof daarentegen doet is beweren dat hij mij beter kent dan anderen op dit forum en insinueren dat ik de inspiratie voor mijn nickname op een revisionistische site zou hebben gehaald, nadat ik daar teksten als de bovenstaande zou gelezen hebben.

Hierbij wil ik echter onderlijnen dat filosoof mij echter niet kent noch ken ik hem. Aangezien hij mijn motivatie voor de nick Darwin evenmin kent is zijn systematische campagne tegenover mij dus geheel ongegrond en niets dan pure laster en verzinsel.
