Early modern human (EMH), or anatomically modern human (AMH), [1] are terms used to distinguish Homo sapiens (sometimes Homo sapiens sapiens) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species (of which some are at times also identified ...

The pattern of differences between Eastern, Central and Southern hunter gatherers when compared to the West African groups which had been found by Hammer was confirmed.
