If you have a pet – dog, cat, bird, rabbit, guinea pig, even a gold fish – you may have already discovered that they do a lot more communicating than you might think was possible without actually being able to talk.
Now people have seen chimpanzees hugging and consoling each other after a fight. They have shown that it actually reduces the stress that they usually feel after a conflict.
It seems that chaimpanzees feel empathy for each other – an ability to put themselves in another’s place and have some idea how they feel. We used to think this was a trait unique to us. http://www.timesonline.co.uk/tol/news/uk/science/article4710629.ece
