What populations have the smallest amounts of Neanderthal admixture?
There are probably no populations that are completely free of Neanderthal admixture, although Central Africans may have the least. Here is a list of populations that generally score lowest on admixture with the Neanderthal Index: Japanese, Swedish, British, Russian, Slavic, Chinese, Sub-Saharan African (especially Central and Mozambican and Angolan) and Indian (when dominant).
