Well, well, well, well, well, well, well.

A study of ancient DNA from people who lived in Europe between 1700 and 45,000 years ago suggests that 63 per cent of them had dark skin and 8 per cent had pale skin, with the rest somewhere in between.

Pre-print reporting again

boothicus.bsky.social•3 days ago

Yeh it’s weird I’d reposted the preprint when it came out a couple of weeks ago just assumed the paper had come out rapidly for some reason. Naughty, but happening increasingly it feels. I guess the results are not so controversial at this stage.

Just did a DNA test and the results would indicate 1% of Jewish Sephardic ancestry. Excitedly reported the news to the wider family that somewhere around the mid 18th century (?) we had an Iberian Jewish ancestor. One relative claimed the test was wrong because we can't have Jewish ancestry. Sigh.

Not impossible, but 1% results on genetic tests are often misreads. Inherent to the way the program assigns it.

1% is incredibly small. I have 6% ethnicity from a great great grandmother who was born about 1840. I would have about 3% from her mother, and 1.5% from her mother (who may be Sephardi btw).

Ethnicity estimates are estimates only. The paper research gives you the answers

I agree. The point about my email was more the reaction of said relative about the possibility an ancestor eight generations back or more was genetically of Jewish origin (but likely converted to Catholicism to stay in Spain).

I wonder why they stopped at the end of the iron age? The obvious question is when did Northern Europe homogenise and presumably we have enough post iron age DNA samples to make that evaluation
