King Richard III's DNA opens a door to a new historical mystery

DNA analysis of King Richard III's skeleton solves one mystery -- and leads to another

It's a 500-year-old missing persons case, and researchers say it has now been solved, definitively.

The missing person was King Richard III, the controversial English monarch, described as having one shoulder higher than another. He ascended the throne in 1483 and died in battle just two years later in August 1485 at the age of 32.

A sprawling research team of archaeologists, historians, engineers and scientists was fairly confident that the twisted skeleton discovered in 2012 beneath a Leicester parking lot where a friary once stood belonged to the king. But now they say they can prove it beyond a shadow of a doubt.



To get the DNA, lead author Turi King of the University of Leicester crushed samples taken from the skeleton's teeth and a small segment of its femur bone into a powder. That powder was put in a solution overnight and then separated in a centrifuge the following day. The powder fell to the bottom of the tube, leaving the DNA in the solution.



"If you look at how likely it is to find a male 30 to 34 years of age, in a specific part of a church, with battle injuries, who had severe scoliosis making one shoulder higher than the other, and combine that with radio carbon dates that match what we know about Richard, and the mitochondrial DNA you get a likelihood ratio of 6.7 million to 1 that these remains are Richard III," she said.

In the paper, the researchers say they are 99.999% certain they have found King Richard.


King also tried to confirm that the bones were those of King Richard by comparing the Y-chromosome DNA of the skeleton with another set of living relatives of the king. This is genetic information that is passed down just through the male line, from father to son.

Genealogist Kevin Schürer, also of the University of Leicester, identified five living males who should have shared the same Y-chromosome as Richard. However, King did not find a match. This suggests that there was a false paternity event at some point in the genealogical tree. And, depending on where that break is, it could call into question the legitimacy of of Henry V's and Henry VI's claims on the throne hundreds of years ago.

"On one level this work has closed a door on the identification of the remains of Richard III, but in so doing it has opened up another door really questioning the succession of the Somersets, the Beauforts and the Plantagenets," Schurer said at a news conference Monday.



2:52 p.m.: An earlier version of this post identified the Beauforts as Beaufords.


There are 19 links in the chain where the false paternity break could have happened (if indeed there is only one false paternity break). Finding out where it (or they) are would involve exhuming skeletons along the chain and checking their DNA against one another.

In other words, it's another historical mystery that only science can solve!
