Extinct species of the genus Homo include Homo erectus, extant from 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). The age of speciation of H. sapiens out of ancestral H. erectus (or an intermediate species such as Homo antecessor) is estimated to have been roughly 350,000 years ago.[note 1] 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 and 30,000 years ago.[4]

This is useful especially for times and regions where anatomically modern and archaic humans co-existed, for example, in Paleolithic Europe.
