• Bonobos and chimpanzees are closely related geneticallyand in many ways behaviorally. • The two species split from a common ancestor around 1 million years ago, both live in fission–fusion societies, with fruit making up the largest portion of theirdiet. (Boesch et al. 2002; Won and Hey 2005;
Furuichi et al. 2008)
• In dyadic food-sharing experiments bonobos are more tolerant when feeding than chimpanzees—even voluntarily sharing food in somecontexts. (Hare et al. 2007; Hare and Kwetuenda 2010). This type of sexual behavior has been hypothesized to serve an important social function in relieving social tension.
