Document Summary
Missing notes for 26, 28, and monday"s class. Homo habilis (~2. 8-1. 8mya)-evidence of stone tools; slightly bigger brain. Homo erectus (~1. 8-0. 4 mya) big brains; more elaborate tools; intentional use of fire; Intentional use of fire, modifying environment: tools with fine detailed retouching, intentionally choosing a particular stone and then working along it; someone sat there and refine this tool to make a pointed edge. Homo sapiens (~200000)-archaic forms, anatomically modern homo sapiens (130 000 ya) Adaptation to cold climate (glacial period) big nose warms up air. Robust crania because cranium reflects industrial use of teeth". Isolation from gene flow with other contemporaneous populations because of glacial climate: specialized offshoot. The idea that neanderthal used teeth as tools, implies that they didn"t have a tool technology but they did: mousterian tool industry. One group says inter-breeding with homo sapiens and eventually died off. One group says totally isolated and we evolved separately.
