Which one of the following phenomena supports Darwin's concept of natural selection in organic evolution?

There are two opposing views about origin of modern man. According 10 one view Homo erectus in Asia were the ancestors of modern man. A study of variation of DNA however suggested African origin of modern man. What kind of observation on DNA variation could suggest this?
