Beringia land bridge: low sea level due to glaciation, refugia for plants, animals, people. Early upper paleolithic siberian culture: 25 000 bp, mal"ta-buret" culture. Hunter-gatherer society of big game (ie mastodons) around lake baikal. Technological innovation (clothing) for first global movements to northern latitudes. Central siberia, genetic ties to north america: potential back and forth movement of gene flow. Clovis culture: buttermilk creek, clovis, tx, projectile style, shape during paleoindian period. Bifacial, symmetric, fluted channel for hafting onto spears. Represents rapid diffusion of founder populations, ability to rapidly adapt to new. Initially controversial environment: clovis was believed to be earliest southern settlement, megafauna extinction. New world fauna had no instinctual fear of humans. Colonization route: ice free corridor, pacific coastal migration. Assumes ice free corridor from beringia to southern canada, northern us.
