Out+of+Africa+Theory

__**Out of Africa Theory **__ The 'Out-of-Africa' theory proposes that 1.4 million years ago //Homo erectus// left Africa and spread throughout Europe and Asia. In Europe, Homo erectus evolved into the //Neanderthals//. In Asia, most Homo erectus stopped evolving - with the exception of a small group in the Indonesian archipelago that branched off to become //Homo floresiensis (//aka the //Hobbit)//. Unlike most of the Homo erectus in Asia, which stagnated, the Homo erectus that stayed in Africa continued to evolve and eventually became //Homo sapiens//. About 200,000 years ago, Homo sapiens left Africa. They spread throughout the globe and conquered or out-competed Neanderthals and Homo erectus. The last Neanderthal died out around 30,000 years ago. The last Homo erectus died out somewhere between 200,000 and 30,000 years ago. The last Hobbit is believed to have died out in a volcanic eruption around 10,000 years ago. After conquering Homo erectus in Indonesia, Homo sapiens moved to Australia. If Homo erectus had made it to Australia first, then they too would have been conquered. In a nutshell, 200,000 years ago an African tribe, either through superior food gathering ability or open war, started the extinction of all hominin species living throughout Eurasia. Supporting the Out-of-Africa theory is work by //Allan Wilson// who provided evidence in 1987 that all modern humans share a single female ancestor who lived in Africa approximately 200,000 years ago.
