Bonobos Are A Bit Promiscuous
These free-loving apes have a strange courtship ritual that involves a lot of promiscuity. They don’t feel jealousy, and members of both sexes engage in courtship activities with one another. They use these rituals to make friends, as currency, form group bonds, and of course, reproduce. Females tend to have more interactions with each other than with their male counterparts. People refer to bonobos as the hippie apes. During a study of bonobos, Martin Surbeck said, “It may be that a greater motivation for cooperation among females, mediated physiologically by oxytocin, is the key to understanding how females attain high dominance ranks in bonobo society.” Oxytocin plays a huge role in their behavior, and females use interactions with each other to establish their equality with males (Medical News Today).
