Re: How does my dog know to look at my face?
What about lions? I suppose in a sense, we've co-evolved with them too and many other animals. I'm not sure this explains it though. Many animals have an affinity for looking into the eyes of another animal. Some view this as a sign of aggression. I forget which animal it is, but upon encountering it, the last thing you want to do is look it in the eye for this will cause it to attack.
