From the article:

We finally observed signals of selection for combinations of alleles that today are associated with three correlated behavioural traits: scores on intelligence tests (increasing 0.74±0.12), household income (increasing 1.12±0.12) and years of schooling (increasing 0.63±0.13). These signals are all highly polygenic, and we have to drop 449–1,056 loci for the signals to become non-significant(Extended Data Fig.10). The signals are largely driven by selection before approximately 2,000 years , after which tends towards zero.

That's the part that the speech police is afraid of.

Why? This article just focuses on changes in West Eurasia (probably because that's what they had data for), but the bulk of changes that resulted in behavioral modernity surely occurred in Africa - where the genetic variability for them to occur was and still is far greater than elsewhere - and plausibly similar changes occurred in other regions such as Central Eurasia, Southeast Eurasia etc. West Eurasia was a backwater.

Sure. But did ALL regions change? And did they change to the same destination? When the environments differed so much? It is easy to see how answers (or the questions themselves) could be politically contentious.

"Surely" without examining the actual evidence is almost surely wrong.
