Last week my Google alert for “genetic genealogy” went crazy, and it took me a few days to realize that Ancestry Magazine recently made all their archives available for free online.Â Although I’m not sure how far back their archives go, there appears to be hundreds of genealogy articles on the site.
A quick search of “DNA” at the site, for instance, reveals MANY articles relating to genetic ancestry testing. This is a great resource for anyone interested in genetic genealogy.
I see that Schelly at Tracing the Tribe had the same Google alerts frenzy last week. As she notes, some of the articles are rather old, so be sure to check the dates before you read them; the information might require some … Click to read more!
I once told someone that in addition to learning about their ancient origins (such as Y-DNA and mtDNA haplogroups), many genetic genealogists would ideally like to match every portion of their DNA with the contributing ancestor.Â Although this might seem to be beyond the reach of current genetic ancestry testing, it has actually already begun.Â The family compare function of 23andMe, for example, is already being used by genetic genealogists for just this purpose; people who have matching DNA segments can compare ancestry and attempt to identify the ancestor who might have contributed the DNA.
For obvious reasons, medical geneticists have for many years been using genealogy to trace founder mutations in populations.Â For example, in 2008 scientists … Click to read more!
From a story in today’s Mormon Times:
The first rumblings about DNA and the Book of Mormon came about 10 years ago, according to Perego, a senior researcher at Sorenson Molecular Genealogy Foundation.Critics cobbled together data from a variety of early DNA studies and came to the unsurprising conclusion that the studies indicated an Asian origin for Native Americans.
This, the critics argued, proved that the Book of Mormon was false. They claimed that the book says the continent was empty and if it was empty, then all Native Americans should have Lehi’s Israelite DNA, not Asian DNA.
Ugo Perego, well-known in genetic genealogy circles, talks with the journalist about the compatibility of our current understanding of Native American origins and the Book of Mormon.Â According to Perego, there are possibilities solutions to this apparent conundrum:
“Try to ask this question to a population geneticist: ‘Is it possible that a small family from Israel could have arrived in America, to a largely populated continent, and that no genetic evidence would survive after 2,600 years?’” Perego says. “Why don’t they ask that question? That is exactly the question they need to ask.”

In the past week there have been so many articles and posts about either genetic genealogy or DTC genetics that Iâ€™m writing them up as a summary post rather than individually.
The New York Times Tackles DTC Genetic Testing
An article in yesterdayâ€™s New York Times by Jane E. Brody â€“ â€œBuyer Beware of Home DNA Testsâ€ â€“ argues that DTC genetic testing is fraught with danger (the article and some of Brody’s arguments are summarized by Grace Ibay of Genetics & Health: â€œSeven Reasons Why Home DNA Tests Are Hypeâ€).Â The author even lumps in genetic genealogy (which has been around for over 9 years now, hardly a â€œnew industryâ€ that has sprung up â€œto cash inâ€ on new science):
â€œAs a source of entertainment at so-called spit parties or an effort to trace genetic ancestry, the tests might be seen as relatively harmless (unless someone is appalled to discover who their ancestors might be).Â But for the many people who are bypassing the medical profession to determine, they believe, how likely they are to develop a life-threatening disorder, experts say direct-to-consumer genetic testing is fraught with potential dangers.â€
Oh no, people might be â€œappalledâ€ to discover their ancestors!Â I can assure you that people were â€œappalled to … Click to read more!
