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).
Stringer was previously one of the leading proponents of the recent African origin hypothesis or ″Out of Africa″ theory, which hypothesizes that modern humans originated in Africa over 100,000 years ago and replaced, in some way, the world's archaic humans, such as Homo floresiensis and Neanderthals, after migrating within and then out of Africa to the non-African world within the last ...
[note 1] The recent African origin paradigm 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 ...
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

The Real Eve: Modern Man's Journey Out of Africa is a popular science book about the evolution of modern humans written by British geneticist Stephen Oppenheimer. The book is largely based on the "out of Africa" theory of human origins. Oppenheimer uses information from various disciplines including genetics, archaeology, anthropology and ...
[97]: 284 Further inland to the Byzantine Exarchate of Africa were the Sanhaja in modern-day Algeria, a broad grouping of three groupings of tribal confederations, one of which is the Masmuda grouping in modern-day Morocco, along with the nomadic Zenata; their composite tribes would later go onto shape much of North African history.
The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003.
The research also located a possible origin of modern human migration in southwestern Africa, near the coastal border of Namibia and Angola. [254] The fossil evidence was insufficient for archaeologist Richard Leakey to resolve the debate about exactly where in Africa modern humans first appeared. [255]
