Different characteristic features of modern humans, such as skin color and hair form, offer substantial clues to ancestral origin (for example, african versus asian). what do we know about genetic variability between the many distinct geographic populations of modern humans? group of answer choices human variation is lower between populations that reside on the same continent, but increases with intercontinental distance. there is very little genetic variation on a regional level, but substantial variation with increasing geographic distance. genetic studies have failed to resolve most population-level differences despite the obvious morphological differences seen between races. the vast majority of variation in humans occurs within, not between, populations. human groups are not genetically distinct.
