Nine pounds seems a bit steep for what you've described @steevc. But I do find it amazing that they were able to identify Richard III remains from 1485!
If I remember rightly it was something to do with the female line and it was a really slim chance that whatever it was would happen.
That's not very helpful is it? I'll have to Google it to remind myself what I'm talking about! 😂
Richard didn't have any children, so they had to trace descendants of his sister. Mitochondrial DNA is passed down the female line and apparently doesn't mutate too much. Leicester University did the research
Ah yes. That must have been it @steevc. I think it meant that every generation had to have had a female child in it and the odds against that were extremely high! 😁
