Researchers found 'an across-species statistical association between same-sex sexual behavior and social behavior,' study author José M. Gómez told Newsweek.
Animals mating with the same sex is a common trait, having evolved so repeatedly in mammals that it is now thought to be helpful for social bonding and reducing conflict.
The advantages of same-sex sexual behavior are manyfold, resulting in its evolution in over 250 mammal species. Stock image of two giraffes showing affection. Same-sex sexual behavior in animals appears to have evolved to help social species bond and avoid conflict."Same-sex sexual behavior does not limit reproduction because individuals engaging in same-sex sexual behavior can also practice different-sex sexual behavior," Gomez said.
The authors of the study note that same-sex sexual behavior is any behavior that is usually performed at some stage during reproduction with a member of the opposite sex, but"does not denote sexual orientation , sexual orientation identity , categories of sexual beings , nor sexual preference," according to Gomez."The definition of same-sex sexual behavior in nonhuman animals is different from how this sexual behavior is considered in human beings.
