Bonobo Males:

Frans De Waal:

"male chimps have evolved into opportunistic strategists, endowed by nature with an appropriately aggressive temper and intimidating pysique. They pack enormous muscles, looking coarse and menacing next to bonobo males with their lightweight bodies and more sensitive expressions.

Life in matrifocal societis has, therefore, created a different kind of male. There is nothing wrong with the bonobo male, even though most men would not want to be like him. He lacks the sort of control over his own destiny that males of their nearest relatives, humans and chimpanzees, claim as their birthright."
