Hi Vince,
My wife is 75% Mexican Indian and her father is R-M269.? Still trying to figure that one out.?
Kind regards,
Joe

I really wish someone would seriously challenge the notion that there's absolutely no R1b inherent in native North Americans.? R1b-M269 is estimated to be approximately 17,000 years old, branching off from R1-M173 just after the last glacial maximum period, during which the Bering Land Bridge was still traverse-able.
noticed that the ancient MA-1 specimen (upper paleolithic Mal'ta¨CBuret' culture from Siberia, the so-called Mal'ta Boy) shares ancestry with both Eurasians and Native North Americans, and is dated to approximately 24,000 ybp. I recall that a genetic genealogist on the old DNA-Forums.org site had investigated the Y-chromosome data for MA-1, and found that he may have branched off at an intermediate SNP within the R1-M173 block.
Consequently I hold onto the hypothesis that some Native North Americans may have branched off between R1-M173 (circa 20,000 BCE) and R1b-P297 (circa 12,000 BCE).
Best regards,
Vince T.
