The latest research on altruism in apes may not be as surprising as the selfless rats in the previous post–because, of course, chimpanzees and humans are much more closely related–but it’s all good, solid evidence that sharing can be as sensible an evolutionary move as selfishness, even if these chimpanzees reported in PLoS do it with non-family members. The same researchers show that both human infants and chimpanzee young will help without expecting a reward. BBC.
