The morals and social structures of the hamadryas monkeys though little known to the general public, the morals of baboons are nonetheless surprising. By describing both their daily activities in captivity in the zoo (where they recreate a complex but stable social life), to following them in their natural habitats in Ethiopia and Saudi Arabia (where they live in nomadic herds), Hans Krummer illustrates that the social organization of baboons is founded on polygamy and mutual respect, which allows them to survive in a hostile environment.Hans Krummer is one of the top specialists in the world on the ethnology of primates. He teaches at the University of Zurich.
