Kanzi is a linguistic all-star among apes. From an early age, the captive bonobo learned over symbols representing words, which he points to, in order to communicate with people. He understands even more spoken English and basic grammar, and followed verbal directions as well as a 2-year-old human during a study conducted in the late 80s. Kanzi may comprehend around words, but there are overin the Oxford English Dictionary.

Non-human primates are marked by well-developed prosocial and cooperative tendencies as reflected in the way they support each other in fights, hunt together, share food and console victims of aggression. The proximate motivation behind such behaviour is not to be confused with the ultimate reasons for its evolution. Even if a behaviour is ultimately self-serving, the motivation behind it may be genuinely unselfish.

The bonobo is distinguished by relatively long legs, pink lips, dark face and tail-tuft through adulthood, and parted long hair on its head. The species is omnivorous and inhabits primary and secondary forestsincluding seasonally inundated swamp forests. Political instability in the region and the timidity of bonobos has meant there has been relatively little field work done observing the species in its natural habitat.

The study of animal sexuality and primate sexuality especially is a rapidly developing field. It used to be believed that only humans and a handful of species performed sexual acts other than for procreation, and that animals' sexuality was instinctive and a simple response to the "right" stimulation sight, scent. Current understanding is that many species that were formerly believed monogamous have now been proven to be promiscuous or opportunistic in nature; a wide range of species appear both to masturbate and to use objects as tools to help them do so; in many species animals try to give and get sexual stimulation with others where procreation is not the aim; and homosexual behaviour has now been observed among 1, species and in of those it is well documented.

A big question is whether the capacity for calculated violence that exists in humans is an inextricable flip side of our ability for selflessness. While it may never be clear why the Delhi rape and murder led to nationwide protests in a country that is so inured to violent attacks on women, it is quite clear that this particular assault stood out for its brutality. No doubt there is such a thing as forced copulation in the animal kingdom that is often violent, and observed in many species of insects and birds such as the mariticidal praying mantis, and among ducks and geese; drakes, more often than not, force themselves on ducks.

Sexual behavior is required for reproduction in internally fertilizing species but poses significant social and physical risks. Females in many nonprimate species have evolved physical and behavioral mechanisms restricting sexual behavior to when females are fertile. The same hormones producing female fertility also control these mechanisms, assuring that sex only occurs when reproduction is possible. In contrast to nonprimate mammals, hormones do not regulate the capacity to engage in sex in female anthropoid primates, uncoupling fertility and the physical capacity to mate.
