Bonobos animal: sex solution problem

Hi steemians,
Who says that violence is the only way to solve a fight because of the seizure of food or territory?
Instead of fighting, bonobos prefer to finish it by having sex. In fact, their entire social structure seems to revolve around sex. Bonobos use sex as a greeting, for dispute resolution, fighting, and in return for a food exchange. This continues every chance there is a friend.
