This very successful group of African origin expanded during the Late Pleistocene first over tropical Eurasia and later into the mid-latitudes where it replaced and partially absorbed other groups of hominins: Neandertals and Denisovans. The oldest known representatives of H. sapiens were discovered in Jebel Irhoud, Morocco and are 300,000 years old. They display a mosaic of derived and primitive features. The former are noticeably expressed in the masticatory system. Among the latter, one should highlight the endocranial morphology that had not yet achieved the globular structure observed in extant humans. These fossils are associated with early Middle Stone Age assemblages also known in eastern and southern Africa. The occurrence of early Middle Stone Age may represent a proxy of the early expansion of our species. Generally, the origin of H. sapiens has been placed in sub-Saharan Africa. However, a pan-African polycentric model of origin is nowadays favored by many scholars.}}, abstract = {{Summary{\textless}br{\textgreater}{\textless}br{\textgreater}Homo sapiens is the only surviving species among a large diversity of Middle Pleistocene hominin lineages.
