When King Louis XVI was beheaded in the former days of the French Revolution , it is said that a hankey hit it up in his blood was set in this calabash ( pictured ) . Now a group of Spanish geneticists have sequenced DNA in the blood , to find out whether it ’s unfeignedly from the king .
First , the researchers sequence the genomes of two of the only eff live on descendant of Louis XVI ’s lineage . These sequence would give them a sense of what variety of transmissible signature they ’d in all probability find in another member of the same family . Then they sequenced the DNA found in the blood - rob cloth . The final result suggest , perhaps not suprisngly , that the blood belongs to somebody else .
pen the researcher in Nature today :
We launch that the ancestry of the gourd ’s genome does not seem compatible with Louis XVI ’s known ancestry . From a functional linear perspective , we did not find an excess of alleles kick in to meridian despite being key out as the tallest person in Court . In plus , the eye colour prediction supported brown eyes , while Louis XVI had risque eyes . This is the first draft genome generate from a person who live in a recent diachronic geological period ; however , our results suggest that this sample may not correspond to the say king .
Whoever ’s DNA this is , he does not meet what the historical record tell us about the Riley B King . The DNA belonged to somebody who was likely not a tall person , and he had brown eyes . But many contemporary witnesses say king was tall with blue eyes . Of course it ’s possible that this succession came from a contaminated sample , given that it has probably been handled by a tidy sum of people over the century . And I suppose you could weave a confederacy story that a patsy was killed in the Riley B King ’s position .
Or you could resolve what the researchers did : This artefact of violent revolution turns out to be emblematic rather than unquestionable .
Demystification of artifacts away , this experimentation is interesting because it ’s the first try that ’s been made to sequence the DNA of a figure from recent history . Previously , scientists have sequence DNA fromice age individual , as well as individuals from two other human group , theNeanderthals and Denisovans . As ancient DNA sequencing perplex tawdry , we may see more historic mysteries being investigated in genetics labs .
