I watched one hunt pheasants from our deck a couple of months ago, in plain daylight. He took off as soon as he saw me. That's one difference already between the coyotes in our area (rural Nebraska) which are shy; and Northeastern coyotes, which IME are much bolder.
The coyote is a very opportunist feeder and he is very adaptable.
None of this rules out genetic adaptation. The wolf and coyote share a recent common ancestor; they still can and do interbreed in the right circumstances. When you look at the difference between a wolf and coyote, particularly eastern Canadian wolves , you're already seeing the effect of evolution. Wolves - near-obligate hunters - are larger and more powerful, with very different behavior. Coyotes, as they relied less of hunting large herbivores, have become smaller. That will continue; the populations that have largely gone over to scavenging will become less shy of humans, evolve dentition that's more characteristic of omnivores and less of carnivores, become smaller, probably less seasonal in their breeding, etc..
Someone asked for a prediction; that's a prediction.
