Press release from Family Tree DNA today:
Family Tree DNA’s Genomics Research Center Facilitates Discovery of Extremely Ancient Root to the Human Y Chromosome Phylogenetic Tree
— By Offering Low Cost DNA Test, Family Tree DNA Aims to Expand Reach of DNA Testing to Encourage Further Exciting Discoveries About Human Origins —
HOUSTON, March 26, 2013 /PRNewswire/ — Gene By Gene, Ltd., the Houston-based genomics and genetics testing company, announced that a unique DNA sample submitted via National Geographic’s Genographic Project to its genetic genealogy subsidiary, Family Tree DNA, led to the discovery that the most recent common ancestor for the Y chromosome lineage tree is potentially as old as 338,000 years. This new information indicates that the last common ancestor of all modern Y chromosomes is 70 percent older than previously thought.
Earlier this week, Ancestry.com began releasing raw data to purchasers of the AncestryDNA autosomal DNA product. Several others have written great articles on AncestryDNA’s new raw data, so I’ll point you to their articles instead of rehashing everything here:
Within the next few weeks and months, you’ll be able to use the AncestryDNA raw data at places like Family Tree DNA and Gedmatch.com.
But note an issue that I first brought up on a mailing list last Thursday when the announcement came out. The following language is found on the page after you click on the final download link:
The raw data is subject to the AncestryDNA Terms and Conditions and AncestryDNA Privacy Statement. You must not use the raw data in whole, in part and/or in combination with any other database for any discriminatory, breach of privacy or otherwise illegal activity (for example, to re-identify any anonymous donor or to make insurance or employment decisions).
