Family Resemblance Across Generations

Did family resemblance across generations come up at your holiday gathering, perhaps in conversation or photographs or both?

Today’s post is about DNA and family resemblance courtesy of abroadintheyard.com, an interesting genealogy website.

The blog author writes:

Resemblance is the basis of our perception of race and ethnicity. It is also a favourite topic of conversation at family gatherings – proclaimed where it is strikingly apparent, or perhaps whispered where it is lacking. Families generally like it when their male biological offspring look like their fathers and females look like their mothers, perhaps with the odd feature thrown in to mark the other half’s creative stamp (“He’s the spitting image of you, but he’s got my eyes”). Some may start life looking like one parent, then ‘morph’ into the other as they get older. Certain facial features may perpetuate for generations, or, fascinatingly, even skip generations. What family historian hasn’t felt a thrill when […]

New DNA Results For Richard III

Word today of new DNA results for Richard III.  In 2012, scientists extracted genetic material from newly discovered skeletal remains unearthed beneath a Leicester parking lot. The results revealed a 99.999% probability that the body was that of the Plantagenet king Richard III, interred at the former site of Greyfriars Abbey after his death in the Battle of Bosworth in 1485.

Interesting new results of continuing analysis of the DNA reveal that genetic material passed down on the maternal side matches that of living relatives, but genetic information passed down on the male side does not.

Professor Kevin Schurer of the University of Leicester notes, “We may have solved one historical puzzle, but in so doing, we opened up a whole new one.”

However, given the wealth of other details linking the body to Richard III, the scientists conclude that infidelity is the most likely explanation.

The researchers took all the information […]

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.
