“Otherwise unrelated domesticated animal species display a range of anatomical and behavioral phenotypes that set them apart from their wild counterparts: depigmentation; floppy, reduced ears; shorter muzzles; curly tails; smaller teeth; smaller cranial capacities; neotenous (juvenile) behavior; reduction of sexual dimorphism; docility; and more frequent estrous cycles. Biologists sometimes call this “domestication syndrome”. Comparing us to Neanderthals, with their larger teeth and brains, and more robust skeletons, it is hard to escape the conclusion that we are the domesticated rather than the wild variant of mankind. Recent genetic studies lend further evidence to this conclusion.”
