Penguins use stones for building their nests. Some pair-bonded female penguins copulate with males who are not their mates and then take pebbles for their own nests. According to the report about the study published by BBC News Onlinesome female penguins sneak around on their partners.
Female chimpanzees living in the wild have been found to engage in a form of prostitution by offering sex in exchange for meat from male chimps. Scientists have found that the bartering of meat for sex takes place over long periods of time and forms part of the social fabric of a troop of wild chimps living in the Tai National Park in the Cote d'Ivoire. Anthropologists have previously suggested that early human societies engaged in meat-for-sex behaviour with the best male hunters having the greatest number of sexual partners.

Anonymous, age and sex unspecified Dear Carole, Why are women so obsessed with the size of a man's cock — wanting ones 6 inches and over and kicking others aside when they really should be concentrating on the emotional connection and love being shared, putting the size of the man's cock right out of her mind?

A lot of sex has taken place since then, and a significant proportion has been motivated by female choice between rival males.
We often look to the behavior of chimpanzees and bonobos to infer the behavior of our ancestors. For example, male coalitionary aggression in chimpanzees is often taken to indicate violent tendencies in humans. Comparative data on bonobos provide a different picture that emphasizes peace and non-violence.
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.
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.
The Evolution of Bruno Littlemore is a novel that is narrated by a superintelligent chimpanzee. Either that sentence made you roll your eyes or it made you excited to read the book ; there's probably not a middle ground. Though I generally despise books written from the perspective of animals, I gave Bruno some leeway because of the low key science fiction trappings.
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.
