"These animals have been domesticated for so long, they must certainly have obtained some human friendly genes through natural selection"
Domesticated species evolve by artificial selection/selective breeding not by natural selection.
- gearhart 11y agoIt's an interesting idea - natural selection not by death before breeding, but by emigration - if only the animals that liked humans stayed near them, and those that didn't went elsewhere, then they'd end up breeding with other "friendly" individuals and you'd have genetic selection pressure that would amount to natural selection.
