4 theories of peopling of the Americas
1) Clovis first
2) Pre-clovis
3) Solutrean hyptohesis
4) early arrival
when did the clovis first theory occur?
during the Pleistocene (ice age) 12,000 ya (close to the end of the ice age)
what route is believed to be taken for the clovis first theory? (FT) (2)
1) From Asia across Beringia
2) Through an ice-free corridor (walking, water wasn’t there)
who is believed to be part of the clovis first theory? (3) (BFI)
1) Big-game hunters
2) fluted clovis points
3) ice-age mega fauna
when did extinction occur during the clovis first occur?
13,000-11,000 ya
what was the extinction most likely caused by?
changing climates
what is a problem found with clovis culture? (3) (TTD)
1) there should be fluted points in Alaska earlier but there’s not
2) timing of the ice-free corridor b/t glacial sheets
3) dates are recalibrated (10,500ya too late)
when did Pre-clovis theory occur?
Arrival 13,000 ya
what route did the pre-clovis theory take?
From Asia via coastal migration
when did the Solutrean hypothesis occur?
15,000-13,000 ya
what route did the Solutrean hypothesis take? (2) (EA)
1) European origins
2) Atlantic “ice edge” route (by boat)
who was part of the Solutrean hypothesis?
Big game (clovis) hunters
what evidence was there for the Solutrean hypothesis?
fluted points similar to the European Solutrean
what problems were seen with the Solutrean hypothesis
1) clovis was 5000 years later than solutrean
2) dangerous passage way requiring maritime skill
3) differences in technology (no channel)
when did the Early Arrival theory take place?
30,000 ya
what route did the Early Arrival theory take?
From Asia via coastal routes
Triggers for domestication of plants and animals worldwide
1) climate change
2) population growth- feedback loop
when did climate change trigger domestication?
at the end of Pleistocene (10,000 ya)
what did climate change create?
new flora and fauna (end of ice ages)
characteristics of domestication in the Middle East
1) “fertile crescent”
2) long transitional process (25,000-7,000 ya)
periods of the Middle East domestication (4) (KNEL)
1) Kebaran
2) Natufian
3) Early Neolithic
4) late neolithic
when did the Kebaran period occur?
25,000-15,000 ya
who was part of the Kebaran period?
hunter-gatherers (short occupation camps)
was there domestication during the Kebranan period?
no
