"Art,
I think we need to be a little more precise. It is true that human beings originated in Africa. The claim that all haplogroups originated there is not true. The reason that haplogroups are of anthropological interest is that they are tied to geography and time (prehistoric). There are only a small number of haplogroups that are tied to Africa. For the Y-chromosome they are A, B, and E. For mtDNA they are the subclades of L. Essentially all of the others originated elsewhere as mutations accrued during migrations around the globe."
=====================================

Currie,

You are absolutely correct. All Haplogroups DID NOT originate in Africa as my statement implied.

My point was that IF Africa was the origin of our species and that as populations migrated from their origins and DNA combinations mutated to create the Haplogroups as we know them today, then it is not to far fetched to believe that in the course of thousands and tens of thousands of years, that the results of those mutations could have found their way back to Africa from Asia causing African/Asian admixtures well beofre the 1800's in America.

I did get 'off track' from the discussion which was about admixture percentages and not Haplogroups.
