A new international study is the first to study the aging habits of multiple species of primates. It finds that, even though we think we are unique when it comes to aging, we aren’t. Humans age very similarly to chimps, gorillas, and other primates.

According to a study headed by British researchers, human children learn new and improved ways to do various activities, but chimps continue to use the first method they learned for doing something, unable, or unwilling, to learn better ways to do it.

A Minnesota-Massachusetts study has shown that small male chimpanzees sometimes become leaders of a group by being nice rather than being strong, aggressive, and large. Grooming other chimps has been found to be a way that smaller chimps get to be the alpha male (leader of the pack).
