Of normal human genetic variation, 1-4% is sourced from Neanderthal DNA, which sub-Saharan African peoples do not share. They still may share up to 96-99% DNA variations. In absolute terms they share in excess of 99.9%[1]. The variations inside ethnic groups are almost 16 times larger than the variations between ethnic groups.
