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.
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?
Female chimps are more concerned with having sex with many different males than finding the strongest mate, according to researchers. The new study by University of St Andrews scientists suggests that female chimps keep quiet during sex so that other females don't find out about it, thus preventing any unwanted competition. They found that chimpanzee females use copulation calls strategically to enlist the future protective support of males against aggressive group members, especially other females.
By Colin Barras. Humans, meanwhile, show a variety of mating behaviours but often form monogamous couples. Michael Jensen-Seaman and Scott Hergenrother at Duquesne University in Pennsylvania think that it is the chimps — not humans — that have experimented with new sexual behaviours since our lineages diverged.
Verified by Psychology Today. Sex at Dawn. Recently, neuroscientist and editor Cara Santa Maria asked me if I could come up with seven things we could learn about love from bonobos, for a Valentine's Day piece.
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.
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.
Wild chimps who regularly gave away food were twice as successful with females as their rivals, researchers found. Previous studies have shown that males chimps often share their meat with females who do not go out to hunt. Although researchers had long speculated that this generosity was used to increase their chances of mating, there was little evidence that this was the case. Infant chimps 'better behaved' than human counterparts.
All rights reserved. Although chimps are found in 21 African nations, conservationists rank them as endangered. Female chimps mate promiscuously so that many males think they might be a baby's father; that discourages infanticide.
Observing a troop in Gombe, Tanzania, Jane Goodall discovered that chimps have personalities, intimate relationships, and agendas. Her work and that of scientists who followed in her footsteps also taught us that chimps are a male-dominant species, prone to not-infrequent violence, with males harassing and sexually coercing lower-ranking female troop members. But our wiring looks less nasty, brutish, and bro-y if we throw over chimps in favor of another close primate relative, the bonobo. On a sunny March day inI stood at the bonobo enclosure of the San Diego Zoo, observing several Pan paniscus performing what struck me as an upside-down, inside-out passion play about gender, power, and aggression.
