Both chimpanzees and bonobos are some of the most social great apes, with social bonds occurring throughout large communities. Fruit is the most important component of a chimpanzee's diet; but they will also eat vegetation, bark, honey, insects and even other chimpanzees or monkeys.
Social learners' fitness decreases as their frequency increases. Social learning does not necessarily mean that the transmitted behavior is the most efficient response to a stimulus. If a socially learned behavior expends unnecessary energy, and there is a more efficient strategy that is not being utilized, employing social learning is maladaptive.
Primates may egage in sexual activity as part of social bonding; includeing homosexual behaviour. [120] Such behavior play an important role in bonobo society in particular. female bonobos engage in mutual genital-rubbing behavior, possibly to bond socially with each other, thus forming a female nucleus of bonobo society.
