ANT317H5 Lecture Notes - Lecture 1: Holocene Climatic Optimum, Beringia, Little Ice Age
Document Summary
Maximum glaciation: 18, 000 bp, no people living, after 18 kya glaciers started to melt, all the landforms we see around us are the result of glaciation. Climate history: 11, 000 bp, taiga - similar to tundra but only in a warm environment, cool temperature, warm temperature, these temperate zones moved north over time. Holocene temperature variations: holocene climatic optimum (hco) - 9-5,000 bp, overall warmer temperature than today. Little ice age - ~ ad 1650: major impact on crops, wind temperatures dropped 1-2 degrees. Peopling of americas: possibly 30, 000 bp. Likely by 20, 000 bp: definitely 15-12, 000 bp. Peopling of the globe: homo sapiens 200-20,000 bp, evolved, adapted, and speciated from all other homo probably in africa. Beringia: 20 - 12,000 bp, connected russia and alaska, also known as the bering land bridge, people in russia used beringia to travel to alaska. North and south america: monte verde, chile mexico, 12,000 bc, meadowcroft, pennsylvania, 18,000 bp.
