Origins of Modern Humans: Migration & Movement
Bering Land Bridge Migration
Out of Africa Theory
Where humans moved
Along the coastlines of Africa, Asia, and Australia
Coastal Migration Theory
Multiregional Theory
Where humans moved
Humans evolved in Africa, Europe, and Asia at the same time
Why they moved
Easy access to food from the sea
Faster and safer travel routes
Why they moved
Continuous migration between regions
Adaptation to local environments
Why they moved
Followed animals during the Ice Age
Lower sea levels exposed land
Where humans moved
From Asia to North America via the Bering Land Bridge
Where humans moved :
From Africa to Europe, Asia, Australia, and the Americas
Why they moved:
Climate changes
Search for food and resources
Evidence used:
Fossils of early Homo sapiens in Africa
Genetic (DNA) evidence showing African origins
One limitation or question
How much interaction occurred with other hominins (Neanderthals, Denisovans)?
Evidence used
Similar skeletal traits across regions
Fossil continuity in different areas
One limitation or question
Genetic evidence strongly favors African origins, challenging this theory
Evidence used
Archaeological sites near ancient coastlines
Tools linked to fishing and coastal living
One limitation or question
Many coastal sites are now underwater due to rising sea levels
Evidence used
Archaeological sites in Alaska and the Americas
Genetic links between Asian and Native American populations
One limitation or question
Exact timing and migration routes are still debated
