There is much debate in the scientific community about the peopling of the Americas. Most of the oldest skulls in the Americas appear somewhat divergent from the traditional phenotype. We can mention Luzia in Brazil(allegedly Australoid), Kennewick Man in Washinghton State(allegedly Europoid or Ainuid) and Penon Woman in Mexico(allegedly Europoid). Then there is the whole question of the Solutrean Hypothesis due to similarities between spears of Europe and North America of the same period. But some studies have largely disproved such an hypothesis. There is much variety among the indigenous peoples of the Americas in terms of phenotype. Some can appear somewhat Europoid(Plains Indians) while others can appear full blown Mongoloid(Eskimos/Inuits and some Amazonian tribes). Others have somewhat of an unclassifiable phenotype(Andeans and some Central Americans). Pretty much all Amerindians from North to South America carry the Q1a3* lineage(specifically M3) in a rather homogenous manner. While the mtDNA looks somewhat more diverse but still appears to come from only 4 women(A, B, C and D). Then there is the fact that mtDNA X is found in some North American tribes as well as controversial R1* lineages which seem to overlap heavily with mtDNA X in distribution. I was thinking about 25 000 years-old Malta boy in Siberia who seems to have carried Y-chromosome R* and mtDNA U. Maybe a related population was more widespread in the Americas during a certain period which may explain the Solutrean-like Clovis artifacts, Kennewick Man and these West Eurasian lineages in North America. For that reason, I suspect the possibility of finding more pre-Columbian Caucasoid mtDNA such as U or H among North American Indians. The problem is that most Native American tribes seem thoughly opposed to DNA testing on both living people of their community as well as ancient remains they argue to be their ancestors( see Kennewick Man controversy). So that may complicate an accurate genetic profile of both the peopling of the Americas and modern Amerindians. What do you people on this forum think? Share.
