Monkey sexuality

Neurobiology pp Cite as. The sexual behaviour of monkeys is very different from that of non-primate species in that it is, to a large extent, emancipated from gonadal control. Female monkeys when paired daily in the laboratory with the male do not show true periodic oestrous behaviour but are prepared to receive the male throughout their menstrual cycle Michael and Welegalla , and for long periods even following ovariectomy Michael and Zumpe Indeed, female solicitations to the males, an index of their willingness to mate, increase after ovariectomy Zumpe and Michael , a finding in marked contrast to many rodent species.

These monkeys are having better sex than you.

Over the past few decades, American society has increased its tolerance and acceptance of differing sexualities. Among the primate order , homosexual behavior is most frequently observed in bonobos. However, it also occurs in other species, such as Japanese macaques and capuchin monkeys. Recent observations of homosexual behavior in male spider monkeys adds to our knowledge of these behaviors and may help us answer questions about the evolutionary functions homosexual behaviors may play, as well as allow us to consider if other animals have sexual orientations similar to the identities that humans construct. From April-December , Laura Busia and colleagues observed three separate instances of homosexual behavior between male spider monkeys. This is particularly notable, given that observing any sexual behavior in spider monkeys is typically rare. Spider monkeys are a challenge to study because they tend to be high up in the tree canopy and can move very quickly through the trees.

The bonobo is distinguished by relatively long legs, pink lips, dark face, tail-tuft through adulthood, and parted long hair on its head. The species is omnivorous and inhabits primary and secondary forests , including seasonally inundated swamp forests. Because of political instability in the region and the timidity of bonobos, there has been relatively little field work done observing the species in its natural habitat. Along with the common chimpanzee, the bonobo is the closest extant relative to humans.
