Document Summary
The holocene: a 12, 000 year history of climate change. Midterm: in this classroom, week after reading week (25th), same time as lecture, 50-60 questions, mc, some matching, t/f, map play, this test will not be related to the textbook. Start to see the genus homo emergy. Marked by glacial-interglacial cycling (cold, warm periods) Time when it is started is debated. Savannah hypothesis: went from warmer to cooler periods, cooled more during the pleistocene, allowed for expansion of grasslands and savannags, set up nice conditions for bipedalism, had to be out on the open plains. Laetoli footprints 1. 3 mya: right at the beginning when afarensis emerged, heel-toe pattern indication of bipedal locomotion. Savanah and out of the trees (above) Correlates with lower sea levels water is bound up in the ice. Interglacial periods have raising of sea levels due to the retraction of ice sheets and glaciers. Stadial (glacial periods cold) and interstadial (interglacial warm) periods.
