Chapter 12- Modern Humans Flashcards
Characteristics of modern humans
High and vertical forehead, a rounded and tall skull, small brow ridges, small face, small teeth
Characteristics of archaic h. Sapiens
Longer lower skull, large brow ridge, bigger more projecting face, taller, wider nasal aperture, a more projecting occipital bone, larger teeth, and no chin
When does the evolution of h. Sapiens begin?
With the emergence of archaic forms- 350,000-500,000 years ago
Where and when did first modern h. Sapiens appear?
Africa 160,000 years ago
What is the Out of Africa hypothesis?
Modern h. Sapiens first evolved in Africa and then spread to Asia and Europe
Explains single origin species of living human by emphasizing single origin and eventual replacement of archaic by modern h. Sapiens
What is the Multiregional continuity hypothesis?
Transition to modernity took place regionally without replacement. Each species of archaic h. Sapiens evolves separately in different parts of the world
Emphasizes importance on gene flow across population boundaries
