White people evolved to live in higher latitudes where seeing better in the dark is a distinct survival advantage (would be my guess). The same is said for blue eyes.
Apparently, white people have larger pupils, and intelligence is unrelated to pupil size aside from its relation to race. What's the theory here, anthropologists? (Military data from 1960-1980s, men only)pic.twitter.com/ic7LCWx9aH

So did East Asians, and yet they have smaller pupils. Maybe that's a body size confound. I don't think this dataset has height, for some odd reason, so I can't adjust.

Northern Europe is higher latitude than East Asia, the mutation could have happened there, especially in places that have very dark winters?

It’s that for light capture in lower light environments?

Yes East Asia is colder than Europe at the same latitudes. Larger pupil size an advantage at higher latitudes

I always assume anything to do with whites is vitamin D related (also circadian maintenance in cloudy environments):https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3572765/ …
