I've enjoyed watching the Genographic Project's various documentaries and reading their published articles, often commenting on them in this blog, so it's a nice opportunity to give something back to the leader of one of the few organizations that is really helping advance our knowledge of human origins.
Here are the results of the admixture analysis: Spencer Wells is in the first bar, and admixture proportions of the 10 components I am using are color-coded for both himself and 36 other populations.
His results are uneventful: his bar is very similar to the one next to it, which summarizes the admixture proportions of 25 individuals from the HapMap-3 CEU population. His top component is North European (60.6%) as his appearance and Northwest European ancestry would suggest. Next is South European (24.9%) and West Asian (13.5%). Rounding up his results is a small slice (1%) of Southwest Asian.
Below you can see Spencer followed by the 25 CEU individuals; these are American Whites from Utah, and as you can see, while there is some small variation in proportions and minor components, he "fits right in" this population.
I have also compared him against the 16 Dodecad Project participants who belong to my "American White" category. This is a rather fuzzy category, consisting of European-descended Americans and Canadians whose ancestry was not entirely from one of my other categories. In that population, the average components are: 11.3% West Asian, 0.2% Northwest African, 26.8% South European, 0.1% Northeast Asian, 1.2% SW Asian, 60.4% N European, 0.1% S Asian, also quite close to Spencer's results.
