Social behavior among primates — including humans — has a substantial genetic basis, a team of scientists has concluded from a new survey of social structure across the primate family tree.This might be exaggerated, because they did not find any actual genes. It has been known for millennia that behavior is a complex combination of nature and nurture, and modern research has not changed that. But they do apply it to human nature:
The scientists, at the University of Oxford in England, looked at the evolutionary family tree of 217 primate species whose social organization is known. Their findings, published in the journal Nature, challenge some of the leading theories of social behavior,
The Oxford survey confirms that the structure of human society, too, is likely to have a genetic basis, since humans are in the primate family, said Bernard Chapais, an expert on human social evolution at the University of Montreal. ...I am waiting for the follow-up editorial on why this shows that we should not expect Mexican, Arab, and Chinese immigrants to assimilate into American culture.
Human multifamily groups may have arisen from the gorilla-type harem structure, with many harems merging together, or from stable breeding bonds replacing sexual promiscuity in a chimpanzee-type society, Dr. Chapais said.
