Summary

If human populations in different geographical regions can be identified by DNA, while the vast amount of human DNA is identical, then, in the regions or places on the genome that are variable, there must be markers that reveal biogeographical regions of origin. DNA polymorphisms (letter changes in the nucleotides) are currently the choice markers because most human polymorphisms are characterized by alleles that are unevenly distributed among the world’s distinct populations.
