 This is all still just theory and not fact, you do realize this?  The Out of Africa theory is also.....a theory. The common consesus among Chinese scientists is that different races of humans evolved separately on different continents and at different times, interesting huh? There have been human remains found in Asia and South America that pre date any humanoid remains found in Africa, interesting huh? I also remember reading an article a month or two ago about the world's oldest human remains being found in SPAIN of all places, the plot thickens.
