Moving the debate forward one step at a time
"Finns have a much higher score than even the Europeans in Utah and British in Britain, but Finns are not particularly tall by north European standards, so what gives?"
They do seem to be taller than Brits though: https://www.ncdrisc.org/height-mean-map.html
I once plotted the genetic distance between germans and the various italian population groups. Not surprisingly, there is a North - South gradient there as well. The goal was to see if the genetic distance was gradually or abruptly increasing with geographical distance to Germany. It was a gradual increase.
heard through the grapevine that southern italy was smarter at some point until some king decided to move all the important stuff up north. History not my strong point tho.
