Anatomically Modern Humans - 5

Out of Africa Hypothesis

Modern humans, Homo sapiens, evolved in Africa and then migrated outward, replacing other archaic humans worldwide

Multiregional Continuity

Modern humans evolved simultaneously in different regions from populations of Homo erectus with ongoing gene flow between regions

Assimilation Hypothesis

Modern humans evolved in Africa, spread globally, and partially interbred with local archaic humans like Neanderthals and Denisovans instead of fully replacing them

rounder/globular skull, vertical forehead, expanded frontal/parietal lobe, tall/smooth occipital, gracile face/mandible, and chin

Cranial Traits

Thinner bones, smoother features, narrow pelvis, longer limb proportions, and adapted to longer distance running

Postcranial traits/Gracility

The set of advanced cognitive and cultural traits associated with fully modern humans and Homo sapiens including symbolic thinking, complex language, art, and sophisticated tool use

Behavioral Modernity

What are the traits of the cognitive abilities in the frontal lobe?

Cognition and emotion, personality, judgment and self control, muscle control, and ST memory

What are the traits of the cognitive abilities in the Parietal lobe?

Sensory processing and language processing

What are the traits of the cognitive abilities in the Temporal lobe?

Auditory processing, LT memory formation, and speech processing

Hypothesis that anatomically modern humans entered the Americas about 13 kya by traveling inland through a gap between the Laurentide and Cordilleran ice sheets.

Ice-Free Corridor Hypothesis

Hypothesis that anatomically modern humans entered the Americas around 16 kya by moving along the Pacific coastline using coastal resources and waterways

Coastal route hypothesis

Upper Paleolithic tool industries

Chatelperronian, Aurignacian, Solutrean, and Magdalenian

Long thin blades made of bone/ivory that could be used as needles from 45kya

Chatelperronian

Long thin blades made of bone/ivory for fishing weights from 43 kya

Aurignacian

Highly refined, symmetrical stone tools (especially leaf-shaped points made by pressure flaking) for advanced hunting weapons from 23 kya

Solutrean

Highly refined bone, antler, and stone tools, as well as extensive cave art and specialized hunting technology from 17 kya

Magdalenian

The shift when humans transitioned from hunting and gathering to farming and domesticating plans and animals around 10 kya

Neolithic Revolution
