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).
The Sumatran rhinoceros (Dicerorhinus sumatrensis), also known as the Sumatran rhino, hairy rhinoceros or Asian two-horned rhinoceros, is a rare member of the family Rhinocerotidae and one of five extant species of rhinoceros; it is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, although it is still a large ...
[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 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 scientific community believe a small species of human known as homo floresiensis once lived on the island of Flores, Indonesia, around 50,000 years ago.But one professor thinks the apelike ...
Imagine life with no humans. One group of researchers has done exactly that -- and they even made a map to show how the world might look sans homo sapiens. SEE ALSO: California drought may ...
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 ...
A critically endangered Sumatran rhino was born in Indonesia’s western island of Sumatra on Saturday, the second Sumatran rhino born in the country this year and a welcome addition to a species ...
