"It's kind of neat to see evolution right there in front of you," says Tonkovich. "This is Darwin stuff, what we learned in biology 101--those that are strongest and smartest will do the breeding. In today's deer management world, our interest is in population dynamics or growing big bucks and age structures and so forth, but this takes you back to the basics of deer behavior and, even more simply, evolution and Darwin's theory of natural selection. "What you're seeing here is one buck trying to convince another that I need to pass my genes on and I'm gonna do what it takes to make sure it happens. This is a manifestation of that drive."
