To best understand and appreciate the relationship of gray wolves (Canis lupus) and white-tailed deer (Odocoileus virginianus) in Minnesota today, information concerning their evolutionary backgrounds is helpful. Modern white-tailed deer have been evolving for about 1 million years (since the Pleistocene epoch). However, artiodactyls (even-toed ungulates or hooved animals) from which they evolved have existed for at least 58 million years (Kulp 1961). Similarly, wolves have existed in their present form for 1-2 million years, but evolved from flesh-eating ancestors that occurred some 45-55 million year ago (Matthew 1930). Because wolves have ranged over most of the Northern Hemisphere, a greater area than inhabited by any of their prey, primary species in the wolf's diet, has and still, depends on geographic location (Mech 1970). Today in the Great Lakes region, and in Minnesota specifically, white-tailed deer are the primary prey of wolves, with moose (Alces alc es) typically being of secondary importance where they both exist (Stenlund 1955, Mech and Frenzel 1971, Van Ballenberghe et al. 1975, Fritts and Mech 1981, Fuller 1989). Clearly, white-tailed deer and gray wolves have helped hone morphological and behavioral adaptations in each other for at least 1 million years of coevolution (Nelson and Mech 1981).
Herein, the objectives of the Minnesota Department of Natural Resources (MNDNR) are to (1) provide a general historical perspective for gray wolves and white-tailed deer in Minnesota and (2) highlight research findings specifically concerning wolf-deer interactions and aspects of each species' ecology pertinent to those interactions.
