Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that ...
In 1962, Coon also published The Origin of Races, wherein he offered a definitive statement of the polygenist view. He also argued that human fossils could be assigned a date, a race, and an evolutionary grade. Coon divided humanity into five races and believed that each race had ascended the ladder of human evolution at different rates. [28]
The concept of racial origin relies on the notion that human beings can be separated into biologically distinct "races", an idea generally rejected by the scientific community. Since all human beings belong to the same species, the ECRI (European Commission against Racism and Intolerance) rejects theories based on the existence of different ...
Human trichromatic color vision had its genetic origins in this period. Catarrhines lost the vomeronasal organ (or possibly reduced it to vestigial status). Proconsul was an early genus of catarrhine primates. They had a mixture of Old World monkey and ape characteristics.
Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers.They migrated out of Africa during the Last Ice Age and had spread across Earth's continential land except Antarctica by the end of the Ice Age 12,000 years ago.
In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) [a] is the mainstream academic [1] [2] [3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).
Conversely, significant rates of modern human gene flow into Neanderthals occurred—of the three examined lineages—for only the Altai Neanderthal (0.1–2.1%), suggesting that modern human gene flow into Neanderthals mainly took place after the separation of the Altai Neanderthals from the El Sidrón and Vindija Neanderthals that occurred ...
Many studies place the average F ST distance between human races at about 0.125. Henry Harpending argued that this value implies on a world scale a "kinship between two individuals of the same human population is equivalent to kinship between grandparent and grandchild or between half siblings". In fact, the formulas derived in Harpending's ...
