I received the following press release today from SMGF:
SALT LAKE CITY (Dec. 30, 2008)â€”Genetic research by the Sorenson Molecular Genealogy Foundation (SMGF) and scientists from ten organizations in Europe and the U.S. shows human groups with the deepest roots in southeastern Europe were not pushed out by an incoming wave of farmer-colonists as agriculture first spread into Europe. Instead, indigenous Europeans with a hunting and gathering lifestyle adopted agriculture when it was introduced by settlers from the Middle East. The study was published in the Dec. 24, 2008 online issue of European Journal of Human Genetics.
Scientists have long debated the question of how agriculture spread into Europe from its birthplace in the Fertile Crescent region of the Middle East. But the evidenceâ€”primarily archaeologicalâ€”is inconclusive.

Most genetic genealogists have sent away their cheek swabs to learn about their mitochondrial DNA or their Y-DNA lines. Others have explored their autosomal DNA for ancestral information, a field that is growing quickly and will undergo rapid changes as the price of sequencing continues to fall.
Now genetic genealogists are beginning to discover the ancestral information locked away in the X chromosome. Indeed, X chromosome tests have been offered by companies such as Family Tree DNA for a number of years. Armed with some of this information as well as the advent of SNP chip information from 23andMe and deCODEme, genetic genealogists are making new discoveries in this very young arena.
The Virginia Commonwealth University Life Science Center has released the results of the VCU Life Sciences Survey and I thought I’d share some of the interesting results.
The most surprising result of the survey is that 80% of surveyed adults favor making genetic testing â€œeasily available to all who want it,â€ similar to values in 2001 and 2004.Â Donâ€™t tell this to the New York and California Departments of Health!
The Benefits Outweigh the Risks
54% of adults believe that the benefits of genetic testing outweigh the risks, while 25% believe that the risks outweigh the benefits.Â Itâ€™s interesting to see the education breakdown of this question.Â 44% of people with a high school degree or less believe that benefits outweigh risks, compared to 67% of people with a college degree or more.Â And 29% of people with a high school degree or less believe that risks outweigh benefits, compared to 20% of those with a college degree or more.

I’m currently in the middle of third-year law school exams, so I thought I’d do a round-up of all the interesting stories I’ve seen over the past week or two.
Holiday Specials on DNA Testing
First, it appears that most of the major genetic genealogy companies are offering special deals for the holidays:
Family Tree DNA announces a holiday sale – FTDNA is offering reducing pricing for customers who are part of or join a DNA project. For example, a 37-marker Y-DNA test is reduced to $119, down from $149.
Ancestry.com announces holiday sale – buy a DNA test between now and December 31st, and you’ll receive 40% off. For example, a 33-marker Y-DNA test is $89.40 (usually $149) and their mtDNA test is $107.40 (usually $179).
A new article in Ancestry Magazine, “Meeting My New Family,” details a recent meeting of genetic relatives in Chicago.Â The author is Howard Wolinsky, who has written other articles in the field of genetic genealogy (see, for example, an article in EMBO about 2 years ago).Â As Howard describes, the meeting wasn’t a traditional family reunion:
“We are a new kind of cousin. Until a few days ago, we were strangers who just happened to have had our DNA analyzed. Then we discovered we matched one another to varying degrees. Most of us have common Jewish connections. And we learned that we come from relatively rare branches of the human DNA tree. Our mothersâ€™ mothers came from the HV branch. Our fathersâ€™ fathers came from the G group.”
Similar to a move made by myHeritage a few weeks ago, Familybuilder has announced that it will offer genetic genealogy testing to its customers.Â As part of the launch of this new product, Familybuilder is offering both Y-DNA and mtDNA tests for only $59.95 until January 1.Â After that, the price will be $89.95
Based on the demo account, it looks like the Y-DNA test includes 17 markers.Â Although this isn’t many markers, $3.52 per marker is a great price.
Familybuilder is planning to continue to develop their genetic genealogy offering: “Currently in development is the ability to create Groups around surnames, families, and other criteria as well as the ability to Compare DNA.”Â From the press release:
â€œUp to now, genealogical DNA testing for the masses has been cost-prohibitive,â€ said David Rheins, CMO of Familybuilder.Â â€œWe are excited about the launch of Familybuilder DNA, and believe that this tool will help millions of consumers better understand the origins of their heritage and ancestry. We are very focused on developing the Familybuilder DNA product line, and have plans to roll out additional tests and future functionality, including the ability to search our DNA database to identify living relatives with whom you share DNA.â€
