Unadmixed Basal Eurasians lived throughout the Near East ~45-15 KYA?

Below is a map from a recent review paper at Trends in Genetics by Melinda A. Yang and Qiaomei Fu titled Insights into Modern Human Prehistory Using Ancient Genomes.

It’s somewhat speculative and an abstract of geographic realities (note that the ancient “Karelia” population is placed several thousand miles east of Karelia, in Northern Asia as opposed to Northeastern Europe). Nevertheless, the fact that the authors chose to illustrate the home of the so called Basal Eurasians as a rather large range in the middle of the Near East, rather than something more remote and limited, like, say, a small part of the Arabian Peninsula or even North Africa, is interesting.
Indeed, they seem to suggest that post-Basal Eurasian Near Eastern populations took shape not as a result of the expansion of Basal Eurasians across the Near East, but rather due the migration of northern foragers (labeled EUR on the map) from Eastern Europe to the Near East. Like I say, no doubt this is based on some guesswork, and needs to be confirmed with more sampling from the ancient Near East, but still noteworthy that it made it onto the map.
