When did man become best pals with the dog? Recent genetic research suggests that dogs may have evolved as recently as 40,000 years ago in East Asia, assumedly through human domestication of wolves.
So how has this tightly coupled evolution affected our relationship with the little woofer? Cognitive research shows that dogs respond to human social cues better than any other animal, including our assumed ancestor, the chimpanzee and their closest extant relative, the wolf. So when you look into your dogs eyes, and you think there is something more there than a blank stare, there probably is.
