Humans have had a very large hand in this evolution.

Dogs are probably the most heavily bred animal in the last 300-400 years. Many (most?) breeds of dogs only exist because humans specifically bred for certain traits.

When breeding for behavioral traits, a dog with expressive eyes who can make humans feel a connection has gotta be a winner over ol wolf eyes over there.

While I agree with your general point, I think livestock is more heavily bred. Chicken, cows, poultry and pigs that "live" in factory farms nowadays can't even survive out in the wild, nor do they have particularly long life-spans.
