Long ago ( maybe 1960 ?), I read a great novel about very ancient Britain, wherein the original people were dark ( very dark hair, not very dark brown, but darkish complected; swarthy is a better term )and on the short side. They were invaded and conquered by blonde, pale skinned people, on the tallish side. So perhaps there is “some” truth to the findings; however, that model is a sick joke and not just PC in the extreme,but RACIST BS! This “finding” is akin to the GLOBAL WARMING hoax!
The Welsh are pretty swarthy, they apparently have more Indo in their Indo-European DNA.
It's one of my all-time favorite books.
“The discovery shows that the genes for lighter skin became widespread in European populations far later than originally thought”
I should have included this quote in my previous comment. So they are basing their conclusions about how widespread light skin was in European populations based on one sample on an island? Great scientific reasoning. Not!
