They come to this conclusion because they find that modern West Eurasians actually have virtually the same amount of Neanderthal admixture percentages as East Eurasians and early West Eurasians and the previous tests found lower Neanderthal admixture percentages in modern West Eurasians than East Eurasians and early West Eurasians because their samples and methodologies were not sufficient enough to discern the effects of West Eurasian gene flow to Africans on the estimations of Neanderthal admixture percentages.<br /><br /><i>and not natural selection against Neanderthal variants or "basal European" admixture from Southwest Europe. This is encouraging as the notion of "basal Europeans" with little or no Neanderthal admixture in Southwest Europe never made much sense to me.</i><br /><br />There is no such thing as Basal European, there is Basal Eurasian. The paper does not refute the idea of Basal Eurasian, it just finds that Basal Eurasians were virtually no different from other Eurasians in their percentages of Neanderthal ancestry. So that means early Basal Eurasians may well have lived in the territories of the Near East with Neanderthal admixture and there is no reason to locate their place of origin in North Africa or East Africa.
