Something is stirring in the undergrowth on the tangled bank... You'll find my evolving thoughts here, but not those of my employer, and certainly not any medical advice...

Watch out for what "Genetic Ancestry" might be telling you!
In my last couple of posts dealing with playing with my 23andMe genome data, I have been exploring genetic ancestry and having a giggle at the numbers that come up. We need to treat these numbers with a certain degree of perspicacity - they don't necessarily mean what first glance would imply. This is not new information - here is Joe Pickrell's blog post on Genomes Unzipped from 2010 dealing with the prediction that he had 20% Ashkenazi ancestry. Further poking suggests that he probably doesn't, but the story of how we can interpret these data is very informative. Highly recommended!
