Document Summary
Anta01- lecture 6 nonhuman primate evolution: the ape-hominin transition. Three genera of great apes: genus pongo: orangutans, genus gorilla: gorillas, genus pan: chimpanzees & bonobos. They are lightly distributed (found only on the islands of borneo & sumatra) Weight varies: males can weigh up too 300 pounds. All of the great apes make nests on the group to sleep (group dwelling) Diet includes leaves, shoots, stems, and some fruit. Largest of the great apes but have a reputation for being gentle giants. Uni-male & multi-female or a couple of males and several females (quite small social organizations) Just as susceptible to ebola like humans and this has wiped out many gorillas. Around the age of 15, they get sexually selected male characteristics (example: silver back) Terrestrial & arboreal (sleep in trees & make nests in trees) Both bonobos & chimpanzees: males stay in communities and females move between communities.
