Document Summary
Africa subsumes all variation from around the world: can be used to see migration patterns. Rearranged all over the place, different chromosomes code for different things. Differential mutation rates (mtdna is faster, 10% more different than chimps) Dendograms longer branches are more genetically different/distant. Species primates/great apes: orangutans, gorillas, chimps/bonobos, humans, gorillas: mountain, west, east (polytypic), live in small groups, avoid each other, major sexual dimorphism, eat plants and insects, different adaptations to elevation (fur and limb length), silver back. Split up into a bunch of different species endangered?! Pan paniscus (bonobos: slender build, longer limbs, medium groups, 90 lb male, 70 lb female, not hunters, eat small mammals though, have social sex to alleviate stress, tools, less diverse. Pan troglodytes (the common chimpanzee: bigger, (130, 70lb), white beards, territorial, tools, cooperative hunting, aggressive, grab testicles, hominids: very little variation in comparison to other primates. Human diversity = variation in subspecies of monkeys.
