The modern human species, possibly evolving out of Neanderthal Man, with the archaic Homo sapiens dating to between c 100,000-33,000 years ago (Homo sapiens neanderthalensis) and the oldest-known anatomically modern Homo sapiens fossils dating between 130,000-80,000 years ago. Modern man - a large, erect, omnivorous terrestrial biped - first appears in the fossil record during the late Upper Pleistocene around 35,000 BC. It is still controversial how Neanderthals were replaced by the modern Homo sapiens. The oldest fossils come from sites in Africa and the Near East. In Eurasia the oldest flint industries associated with Homo sapiens are always of Upper Palaeolithic blade-and-burin type. Modern man's technology replaced that of the Mousterian period.
