There are two opposing views about the origin of modern man. According to one view, Homo erectus in Asia were the ancestors of modern man. A study of variation of DNA however suggested the African origin of modern man. What kind of observation of DNA variation could suggest this?

1.	Greater variation in Asia than in Africa
2.	Similar variations in Africa and Asia
3.	Variation only in Asia and no variation in Africa
4.	Greater variation in Africa than in Asia
