Elizabeth Warren's Latest 'I'm an Indian' Salvo


The mainstream media is abuzz about Sen. Elizabeth Warren's (D-MA) latest salvo in her battle to validate her claim to American Indian ancestry. Out of curiosity, I had a look at the report Warren commissioned from a "famous geneticist", i.e. Carlos Bustamante, PhD.

A few things that I haven't seen discussed in the mainstream media stand out to me. First, the Bustamante report has no discussion about how it was verified that Warren provided the sample that was tested and how the chain of custody was maintained and verified.

Second, it is curious that Bustamante does not more specifically identify the segments he used to conclude that the results of Warren's test "strongly support the existence of an unadmixed Native American ancestor". He merely speaks of "five genetic segments", averaging 5.8 centiMorgans long (with the longest being on chromosome 10). Bustamante says the entire human genome is 3,595 centiMorgans long.

Finally, check out the image below from the Bustamante report. Notice anything major missing?


If your answer was "only the most populous continent on earth" then you get a gold star. Yes, Asia is missing, and since most geneticists believe American Indians descend mainly from early Asian immigrants to the Americas then inquiring minds wonder what that scatterplot would look like if Asians had been included. And how did Bustamante decide that the "five genetic segments" in Warren's putative DNA aren't from long ago admixture with an Asian ancestor—a Hun or Magyar, perhaps?
