Hei,
The author of the article, Bryan Sykes, a professor of human genetics at Oxford, "pionered the use of DNA in exploring the human past." He founded and chairs www.OxfordAncestors.com <128SPORTS: SLOT INDONESIA 128SPORT JUDI BOLA GACOR ONLINE SBOBET, "which helps individuals explore their genetic roots using DNA." He's also written books on the subject, both technical, and for the lay genealogical audience.
One of his projects was on the genetic history of Britain and Ireland, based on mDNA and the Y chromosome. He didn't think this could be done in America, given its greater geneic diversity. A new technique, developed in
2009, called "chromosome painting," "looks at the myriad other segments of DNA inherited from our ancestors." As those who've had their DNA 'done" know, more and more markers have become available, enabling better and better tests. The new "chromosome painting" insofar as I understand it--which isn't very well--uses up to a million markers! It is therefore much more expensive, I'm sure, though he doesn't say so.
In 2009, Sykes began to ask for volunteers for his first field test, to search for ancestors who were European, African, and Native American. He had a special interest in seeing whether immigrants intermarried/interbred with indigeneous peoples, since this tends to be a pattern in other parts of the world. *(Bev, this is what prompted me to note this article alongside your resources on the Vikings!)*
** While he doesn't say how many volunteers he had from New England, given the depth of historical background most genealogists from New England tend to have on their ancestors, many would have the records going back to their immigrant ancestors, to correlate with the DNA results. Sykes found not a single case of intermarriage/interbreeding among the New Englanders in his sample. I guess they really were Puritans! Or, as he noted, it is possible that the children in such unions were raised within the native community.
However, among the Dutch immigrants in New Netherland (mostly in modern NY state), he found one case. This was a very famous historical example, in fact one of my ancestors by marriage, a Mohawk princess who married a Dutch immigrant.
Sykes also noted that given how many generations intervened--the Mohawk princes lived in the mid 17th c.--her 21st c. descendant might well not have gotten any of her chromosomes at all. That he did was pure chance.
This case was, historically, not the only known example, but the only one he found.
