Just a note on dog evolution:
I am an animal behavior major taking a course on the behavior and evolution of dogs, and the most prevalent theory in the literature is that dogs evolved naturally from wolves based on flight distance, which in turn led to a number of other changes. They were dump dwellers, and got more nutrition from the dump than other wild animals because of the decreased flight distance. They were then taken in and selectively bred. They are genetically predisposed to short flight distances and easy inter species socialization. (Coppinger and Coppinger 2001) The studies with the bayelev foxes shows that simply selecting for flight distance causes a number of changes in appearance, including patchy coats, curled tails and floppy ears, all of which are characteristics of domestic dogs and not wolves.
Sorry, I just get excited when I know things.:crazy01:
