A brief wikipedia search suggests a lot of humanity has Neanderthal DNA, not just Europeans. Neanderthals shared more alleles with Eurasian populations (e.g. French, Han Chinese, and Papua New Guinean) than with sub-Saharan African populations (e.g. Yoruba and San).[8] According to the authors Green et al. (2010), the observed excess of genetic similarity is best explained by recent gene flow from Neanderthals to modern humans after the migration out of Africa.[8] They estimated the proportion of Neanderthal-derived ancestry to be 1–4% of the Eurasian genome.
