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.
