COP: Bonobo mothers will help their sons courtship

WASHINGTON, May 21 (Xinhua) -- An international team of researchers has found for the first time that bonobo mothers help bonobo sons increase their chances of courtship by "repelling opponents" and "creating opportunities," but bonobo daughters do not receive similar help.

Research published on the 20th in the American journal "Contemporary Biology" showed that bonobo mothers would prevent or disrupt mating with other males and bring their sons to the vicinity of females who were in the ovulation period, thus increasing their son's chances of becoming a father by about twice.

A team of researchers led by the Max Planck Institute for Evolutionary Anthropology in Germany made a comparative look at wild bonobo populations in the Democratic Republic of the Congo and wild chimpanzee populations in Côte d'Ivoire, Tanzania and Uganda.

They found that both bonobos and chimpanzee mothers help their sons in male fights, but bonobo mothers do more to help their sons courtship.

Studies have shown that because bonobos live in a matriarchal society, bonobo mothers use their position in the population to elevate their sons' status among groups, giving them better chances of courtship. However, this interference rarely occurs in chimpanzee societies because male chimpanzees have a much higher status than female chimpanzees, resulting in female chimpanzees behaving less influentially than female bonobos.
