Midterm 1: People of the america and rise of Agriculture Flashcards
(45 cards)
What are the 4 theories of peopling the new world?
Clovis, Pre clovis, Silurian Hypothesis , Early Arrival
Route of Clovis First
From Asia across Beringia through ice free corridor
What time period was Clovis First
Pleistocene, 12,000ya
Blackwater Draw, NM
Clovis First
1st Discovery of clovis points with megafauna remains 13,000ya
Gault , Texas
Clovis First
incised limestone slab, unclear
Problems with Clovis First
Should find fluted points earlier in Alaska but don’t
Also timing of the ice free corridor too late
When was pre clovis
13,500 +
Route of pre clovis
From asia via coastal migration
Monte Verde, Chile
Pre clovis
15,000 ya
Settlement with wood and hide tents
organic remains, not clovis, seeds=foraging,coastal resources
What are the problems with pre clovis
Meadowcroft: contaminated dates
Coastal migration route: no coastal sites
what time frame was Solutrean Hypothesis
15,000-13,000 ya
Route for Solutrean hypothesis
European origins
Atlantic “ice edge route
Evidence of Solutrean Hyothesis
fluted points similar to European Solutrean
Meadowcroft Rockshelter “Miller Point”
Problem with Solutrean Hypothesis
Clovis is 5,000 years later than Solutrean
Dangerous passage require maritime skill
No channel
Time frame for Early Arrival
30,000 +
Route for Early Arrival
from asia via coastal route
Yana River, Siberia
Early Arival
30,000
evidence near Beringa
Megafauna bones and flake tools
Pedra Furada, Brazil
Early arrival
48,000-35,000
Burnt earth
simple tools
Genetic evidence for peopling of the America
5 clades of native people traced to Siberia
mtDNA traces to Siberia & Mongolia
Combined evidence of genetic and linguistic data
Siberian/Asian origin single migration with group branching Pre Clovis - 15,000 or earlier coastal route mixed hunters and foragers
Where did the rise of agriculture happen
middle east
When did the rise of agriculture
Neolithic revolution
Transition to farming impacts
Diet- food groups
Health and disease
physical activity
Triggers of domestication
Climate change
population growth - feedback loop
