Homo sapiens (red) Expansion of early modern humans from Africa through the Near East. In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) [a] is the most widely accepted [1] [2] [3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).
Human migration routes following Out-of-Africa. Most modern Africans display a high level of genetic homogeneity, but contributions from Eurasian populations are substantial, mostly concentrated in the Northeastern part of Africa and Madagascar. The "recent African origin of modern humans" proposes a "single origin" of Homo sapiens within ...
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
[note 1] The recent African origin theory suggests that the anatomically modern humans outside of Africa descend from a population of Homo sapiens migrating from East Africa roughly 70–50,000 years ago and spreading along the southern coast of Asia and to Oceania by about 50,000 years ago. Modern humans spread across Europe about 40,000 years ...
The fossil record shows Homo sapiens (also known as "modern humans" or "anatomically modern humans") living in Africa by about 350,000–260,000 years ago. The earliest known Homo sapiens fossils include the Jebel Irhoud remains from Morocco ( c. 315,000 years ago ), [ 29 ] the Florisbad Skull from South Africa ( c. 259,000 years ago ), and the ...
Modern humans are thought to have evolved in Africa at least 200 kya (thousand years ago), [32] with some evidence suggesting a date of over 300 kya. [33] Examination of mitochondrial DNA (mtDNA), Y-chromosome DNA, and X-chromosome DNA indicate that the earliest population to leave Africa consisted of approximately 1500 males and females. [ 32 ]
It is believed, on the basis of genetic evidence, that all human beings in existence now descend from one single man who lived in Africa about 60,000 years ago. [2] The earliest groups of humans are believed to find their present-day descendants among the San people, a group that is now found in western southern Africa. The San are smaller than ...
The genetic history of Southern Africa encompasses the genetic history of the people of Southern Africa. The Sahara served as a trans-regional passageway and place of dwelling for people in Africa during various humid phases [ 1 ] [ 2 ] [ 3 ] and periods throughout the history of Africa .
