Nineteen Living Descendants of Oetzi the Iceman

Remember Oetzi (or Ötzi, if you prefer), the Copper Age Tyrolean Iceman, whose 5,300-year-old frozen body was found in the Austrian Alps? Thanks to ancient DNA, nineteen living descendants of Oetzi the Iceman have been found in the Tyrol.

Discovered in September 1991, Oetzi was named for the place where he was discovered, in the Ötztal Alps on the border between Austria and Italy. Scientists estimate Oetzi the Iceman lay undiscovered for 5,300 years.

The EURAC-Institute for Mummies and the Iceman uses minimally invasive “investigation methods, such as computer tomography, nanotechnology, molecular and biological approaches, as well as ancient DNA research.”

It’s that ancient DNA research that’s so cool to us genealogists. Scientists compared Oetzi’s genome with modern European populations and discovered 19 living descendants in the Tyrolean region of Austria. Yet, most interestingly, they believe the Iceman was most closely related to men from Sardinia and Corsica.

Genetic Genealogy Helps Identify the Skeleton of King Richard III

Genetic Genealogy Helps Identify the Skeleton of King Richard III!

Last September, an archeological dig in Leicester, England, discovered what was believed to be the bones of King Richard III after the skeleton was found buried six feet below a municipal parking lot. The team of archaeologists, historians, genealogists and geneticists who worked to make the identification announced today that the find is authentic. The New York Times:

The geneticist Turi King told a news conference held by the University of Leicester research team that DNA samples taken from two modern-day descendants of Richard III’s family matched those from the bones found at the site. One of the descendants, Michael Ibsen, is the son of a 16th-generation niece of King Richard’s. The second wished to remain anonymous, the researchers said.

The bones will be reinterred at Leicester’s Anglican cathedral in a service sometime next year after research is complete.

Your Privacy and Genetic Genealogy

Faithful readers who have been asking where I’ve gone to: Sassy Jane will be back in early February. In the meantime, did you see this article in the New York Times on privacy of DNA information?

From the article:

The genetic data posted online seemed perfectly anonymous — strings of billions of DNA letters from more than 1,000 people. But all it took was some clever sleuthing on the Web for a genetics researcher to identify five people he randomly selected from the study group. Not only that, he found their entire families, even though the relatives had no part in the study — identifying nearly 50 people.

The data are from an international study, the 1000 Genomes Project, that is collecting genetic information from people around the world and posting it online so researchers can use it freely. It also includes the ages of participants and the regions where they live. That […]

DNA Results in Michelle Obama’s Family Tree

Interesting article today in The New York Times on continuing research on Michelle Obama’s family tree, including DNA results that link her to distant cousins.

The discovery of this unexpected family tie between the nation’s most prominent black woman and a white, silver-haired grandmother from the Atlanta suburbs underscores the entangled histories and racial intermingling that continue to bind countless American families more than 140 years after the Civil War.
