1h 1min, jan 1, 300000 y BC - Appearance of Homo Sapiens
Description:
Approximate date of appearance of Homo sapiens (Jebel Irhoud, Morocco).
In taxonomy, Homo sapiens is the only extant human species. The name is Latin for "wise man" and was introduced in 1758 by Carl Linnaeus (who is himself also the type specimen).
Extinct species of the genus Homo include Homo erectus, extant during roughly 1.9 to 0.4 million years ago, and a number of other species (by some authors considered subspecies of either H. sapiens or H. erectus). H. sapiens idaltu (2003) is a proposed extinct subspecies of H. sapiens.
The age of speciation of H. sapiens out of ancestral H. erectus (or an intermediate species such as Homo antecessor) is estimated to have taken place at roughly 315,000 years ago. Sustained archaic admixture is known to have taken place both in Africa and (following the recent Out-Of-Africa expansion) in Eurasia, between about 100,000 to 30,000 years ago.
The term anatomically modern humans (AMH) is used to distinguish H. sapiens as having an anatomy consistent with the range of phenotypes seen in contemporary humans from varieties of extinct archaic humans. This is useful especially for times and regions where anatomically modern and archaic humans co-existed, for example, in Paleolithic Europe.
Jebel Irhoud (Moroccan Arabic: جبل إيغود, žbəl iġud pronounced [ˈd͡ʒabal ˈʔiːɣuːd]) is an archaeological site located just north of the locality known as Tlet Ighoud, about 50 km (30 mi) south-east of the city of Safi in Morocco. It is noted for the hominin fossils that have been found there since the site's discovery in 1960. Originally thought to be Neanderthals, the specimens have since been assigned to Homo sapiens and have been dated at 315,000 years old.
