GEOG 205 Lecture Notes - Short-Faced Bear, Laurentide Ice Sheet, Woolly Mammoth
Document Summary
No, they were not around at the same time there were mammals around at the same time, but not humans: only showed up at the beginning of the quaternary. By 11 000 years ago there was another major extinction during the last glacial maximum. Mammal content of the earth was much larger. What was lost? lots of animals lost below the laurentide ice sheet some lost around the world, others only in north america: saber tooth cat, american lion, sloths, short faced bear, mastodon & woolly mammoth. Megafauna were present throughout many fluctuations in temperature. Africa suffered the least in extinctions, but humans were always there. Because humans evolved in africa could animals have adapted to the human presence? some argue humans rapidly had developed rather effective technologies & arrived in na with them ie/ clovis points. Europe: has great evidence & there is lots of pictorial evidence, early european architecture.
