BIO 346 Lecture Notes - Lecture 19: Bornean Orangutan, Western Gorilla, Bonobo
Document Summary
Fishing needles, flutes, needles (sewing), necklace pieces, etc. Used to define the boundary by 14 kya. See bits of this at 60-70 kya - when we started to move out of africa. As fossil record becomes richer see bigger brain size. Where does this behavioral complexity come from? (are there antecedents ( a thing or event that existed before or logically precedes another) in other species?) Hominin - fossil ancestors (homo & chimps) Large brains, complex behavior, long gestation times, no tail. 2 types of chimps (pan) - closer related to each other than us. Both are closer related to us than gorillas. ~ 100 lbs (males - 120, females - 90) Polygynous - many males mate with many females. Polyamous - 1 male mates with many females. Live in equatorial africa (specifically in rainforest near congo. ~ 85 lbs (males - 95, females - 75) - slightly smaller than chimps. Quadrupedal - knuckle walking & tree climbing.
