Warren releases results of DNA test - https://www.msn.com/en-us/news/politics ... spartanntp
This news item is interesting in the Ashkenazi context because of the generational estimates.
In the Ashkenazi situation, the times are much more distant, even the most recent estimate, makes 1/512 look like an extremely large number.
This news item is interesting in the Ashkenazi context because of the generational estimates.
The article goes on -The analysis of Warren’s DNA was done by Carlos D. Bustamante, a Stanford University professor and expert in the field who won a 2010 MacArthur fellowship, also known as a genius grant, for his work on tracking population migration via DNA analysis.
He concluded that “the vast majority” of Warren’s ancestry is European, but he added that “the results strongly support the existence of an unadmixed Native American ancestor.”
Bustamante calculated that Warren’s pure Native American ancestor appears in her family tree “in the range of 6-10 generations ago.” That timing fits Warren’s family lore, passed down during her Oklahoma upbringing, that her great-great-great-grandmother, O.C. Sarah Smith, was at least partially Native American.
In this case, however, there is the evidence of the family legend which is a strong argument for believing the more recent possibility; not to mention the inherent stupidity of making a 1/512 argument.The inherent imprecision of the six-page DNA analysis could provide fodder for Warren’s critics. If her great-great-great-grandmother was Native American, that puts her at 1/32nd American Indian. But the report includes the possibility that she’s just 1/512th Native American if the ancestor is 10 generations back.
