Why are the evolved chimps not evovled or gay

A new study found that same-sex sexual behavior helps establish and maintain positive social relationships in animals including chimpanzees, bighorn sheep, lions, and wolves. The team believes that this suggests the behavior may be an adaptation meant to mitigate the risks of violent conflict between males.

For one population of male macaques , same-sex sexual behavior may even be a common feature of reproduction and is related to establishing dominance within groups, handling a shortage of different-sex partners, or even reducing tension following aggressive behavior.

Harvard University primatologist Christine Webb, who did not participate in the study, told The Washington Post that the findings add to other research and widen the scope of what it means for a behavior to be considered adaptive. All life forms are super similar to their parents but have some differences for many reasons including mutation.

In this new study , the team from institutions in Spain surveyed the available scientific literature to create a database of records of same-sex sexual behavior in mammals. Importantly, they caution that the study should not be used to explain the evolution of sexual orientation in humans.

The behavior is particularly prevalent in nonhuman primates. Terms of Service and Privacy Policy. More deals, reviews, and buying guides The PopSci team has tested hundreds of products and spent thousands of hours trying to find the best gear and gadgets you can buy.

The team found that same-sex sexual behavior is widespread across mammal species, occurs in s imilar frequency in both males and females , and likely has multiple independent origin points. This research focused on same-sex sexual behavior defined as short-term courtship or mating interactions, instead of a more permanent sexual preference.

A study published October 3 in the journal Nature Communications suggests that the behavior possibly plays an adaptive role in social bonding and reducing conflict, and evolved multiple times. This analysis found that the behavior helps establish and maintain positive social relationships in animals including chimpanzees, bighorn sheep, lions, and wolves.

Environment, not evolution, might underlie some human-ape differences. 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. Deposit Photos.

Over 1, animal species, from bonobos to sea urchins to penguins are known to engage same-sex sexual behavior. Webb also added that it makes sense that other animals would have sex for a variety of reasons the way that humans do. It has been observed in at least 51 species from small lemurs up to bigger apes.

Additionally, male same-sex sexual behavior was likely evolved in species with high rates of male adulticide—-when adult animals kill other adults. While some say the behavior might have existed since the animal kingdom first arose more than half a billion years ago , it may have actually evolved repeatedly in mammals.

Apes’ abilities have been unfairly measured, throwing into doubt the assumed belief that human infants are superior to adult chimpanzees, according to a new study by leaders in the field of ape cognition. Evolution can be boiled down to just a couple key points: Offspring inherit traits from their parents but are not clones.

The authors caution that these associations could also be driven by other evolutionary factors. Same-sex sexual behavior has also only been carefully studied in a minority of mammal species , so our understanding of the evolution of same-sex sexual behavior may continue to change as more mammalian species are studied.
