Document Summary

Dog is the first domesticated animal (before plants + animals) Climate change - genus homo is evolving thruout this period. During cold period glaciers grow by sucking up moisture and locking up in ice. Grasslands can expand with lowered sea lvl. Sea lvl = easier to cross land bridges . Land bridges - land connections can form when glaciers lower sea lvl. 65kya ago is the earliest site (rock shelter) in aus. When ppl reached sahul, it was a new environment w/ strange animals (larger versions) Ppl colonized 25000 kya using the beringia (bering land bridge) Sea lvl dropped ~100m so the ppl could cross the land bridge, most likely following game. 2 major hypothesis on how the americas were ppled. Ppl came down the coast of n. america and moved eastward into the lower continents. Moved quite rapidly since they didn"t have to adapt to new environments (cultural adaptation)
