Small-Scale Question Sunday for June 8, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

It’s said that the reason Northern European Ashkenazim often have light eyes and light skin is because these genes were selected for over ~1000 years. Doesn’t this mean that the health consequences of inadequate vitamin D are more serious than commonly considered? Given that the predominant darker skin tones must have been significantly selected against. And doesn’t this poke a hole in the theory that pale skin was sexually selected, given that Ashkenazim marriage patterns were mostly predicated on business ties and rabbinical performance, rather than an individual’s own tastes?

Why are you “it’s said”ing? We have genomic data. Wikipedia:

A 2013 study of Ashkenazi mitochondrial DNA by a team led by Martin B. Richards tested all 16,600 DNA units of mtDNA, and found that the four main female Ashkenazi founders had descent lines that were established in Europe 10,000 to 20,000 years in the past[165] while most of the remaining minor founders also have a deep European ancestry. The study argued that the great majority of Ashkenazi maternal lineages were not brought from the Near East or the Caucasus, but instead assimilated within Europe, primarily of Italian and Old French origins.[166] The study estimated that more than 80% of Ashkenazi maternal ancestry comes from women indigenous to (mainly prehistoric Western) Europe, and only 8% from the Near East, while the origin of the remainder is undetermined.[167][165] According to the study this "point to a significant role for the conversion of women in the formation of Ashkenazi communities."

They’re just Europeans, albeit from a parallel, ancient strain. The men are the ones with strict Levantine ancestry.

The pale eyes are a dead giveaway. Northern latitudes are perfectly compatible with dark eyes.

Edit: kept reading, and more recent studies estimate more and more European ancestry. So it goes.

I know about the DNA research but the average Hasidic Jew still looks more pale than the average Italian (Hasidim being a good example of “pure Ashkenazim”)
