Is there any serious analysis of whether Germanic settlement in Northern Italy in 500 to 700s is one of the major reasons why northern Italy dominates the south? How large was the genetic impact? Can we run admixture studies? https://en.wikipedia.org/wiki/Lombards pic.twitter.com/yl3mGd3an4
Maybe Lynn got it wrong. He mainly proposes that Southern Italians mixed with Northafricans and got some lower IQ admixture, but maybe it's the other way around: the North Italians mixed with the Germanic invaders and that's how they got their genetic advantage.
Couldn't it just as easily be due to internal migration within last few centuries, a la what Clark proposes happened in England? https://voxeu.org/article/decline-northern-england-1780-2018 …pic.twitter.com/6WJCXEqoys
For that, you would need the elites to move from south to north Italy, which would show up in last name analysis. It had to be very early because the differences go back 500 years or more. https://www.gwern.net/docs/iq/2010-lynn.pdf …pic.twitter.com/4mzZH6ecLw
My thinking is that these peoples were low in high culture (no proper written culture etc.), but superior in genetics, which would only show up much later when they were more pacified and encultured.
emil, u don't think higher iq is a result of selection in urban environments? the more "urban ancestry" u have, the higher fitness u have in city occupations (and modern world)? u think one can create a model for genetic impact by invaders or too much variance in diff. cases?
Finland has probably highest IQ in Europe and not much “urban ancestry”
Hmm. What u say is true.
Though, there may have been different ecologies favoring higher IQ. The one for Finns different from Jews for instance
ofc it doesn't have to be all the same as u say. the boiz say climate and large pop is the keys. and it seems to fit very well. am thinking that tambrahms and leb xtians are exceptions. but they are also minorities so harder and diff pressure apply 2 them.
but am thinking islamic golden age. why does it happen in warmer climates?? that's where am thinking urban ancestry comes. am thinking greeks. am thinking rome. same thing, urban ancestry. they get genes that give high fitness in cities. what u think?
But why did the city States of northern Italy vastly outperform their Germanic counterparts on virtually every scale imaginable during the middle ages?
Hmm possible, but doesn't seem likely. Not to mention most Northern Italians counterintuitively have more EEF contributions than Southern Italians.https://www.sciencedirect.com/science/article/pii/S0960982215009495 …

*analyses *convincing :D.
Northern Italy shows more R1b ydna than southern Italy which could be Germanic but more than likely is Celtic/Bell Beaker/Italic...I1 ydna could show Germanic ancestry...
