The human ego has never been quite the same since the day in that Jane Goodall observed a chimpanzee feasting on termites near Lake Tanganyika. After carefully trimming a blade of grass, the chimpanzee poked it into a passage in the termite mound to extract his meal. No longer could humans claim to be the only tool-making species.

Female chimpanzees treat sticks and small logs as dolls by cuddling them, creating games and even putting them to bed, new research finds. Since young male chimps were less inclined to play dollies, the authors say their study presents the first evidence of an animal species in the wild in which play differs between males and females. The new observations, published in the latest Current Biology, come from Kahlenberg and colleague Richard Wrangham's 14 years of studying the Kanyawara chimpanzee community in Kibale National Park, Uganda.

This reveals their promise as a model of human mental illness. In people, as well as primates, self-grooming actions like head scratching or beard stroking can indicate anxiety, uncertainty, social tension, and impending danger. For the current study, researchers assessed scratching behaviors in 76 chimpanzees that were socially housed at the Yerkes National Primate Research Center. Half of the chimpanzees exhibited DupA, one form of the vasopressin V1a receptor gene, which is responsible for complex social behavior.

Though chimpanzees and humans share about 99 percent of the same DNA, numerous physical and behavioral traits separate us from our closest living relatives. But are we different even when it comes to sex? Just how do chimpanzees "do it?

The theoretical debate over the relative contributions of nature and nurture to sexual differentiation of behavior has increasingly moved towards an interactionist explanation requiring both influences. In practice, however, nature and nurture have often been seen as separable, influencing human clinical sex assignment decisions, sometimes with disastrous consequences. Effects of the social environment and gender expectations in human cultures are ubiquitous, overshadowing potential underlying biological contributions in favor of the more observable social influences.

The common chimpanzee Pan troglodytes and its close relative, the bonobo Pan paniscus are the closest relatives to Homo sapiens alive today. Like humans and other primates, chimps are social animals, forming relatively stable but fluid communities, with males, females, adults and adolescents living in close proximity over extended periods. Compared with their human counterparts, female chimps tend to be more promiscuous and go longer between births; both male and female chimps employ a greater variety of reproductive strategies than humans do.

After the ordeal the alhaji went to drop her and drove off, few hours later she started complaining of stomach ache, she thought it was normal thing, but from what we gathered fews hours later, maggots start coming out from her private parts, her friend tried to rush her to the hospital but it was too late………….

Male chimps apparently can win over the opposite sex with the aid of fruit stolen from nearby farms and orchards. The discovery could shed light on the evolution of the sharing of food and more complex behaviors among humans, Hockings added. Over the course of a year, Hockings and her colleagues investigated how wild chimpanzees coexisted with people at the West African village of Bossou in the Republic of Guinea. They're the totem of the village, so people don't kill them," Hockings told LiveScience.
