Due to the Neanderthal genome project, we now know that Europeans and Asians have Neanderthal ancestors. However, humans below the Saharan Desert do have posses any Neanderthal DNA.
A group created complete DNA sequences of fifteen Africans. Five males from three different very distinct populations groups. This included five Pygmies from Cameroon, five Hadza from Tanzania, and five Sandwe from Tanzania. They found evidence of an unknown extinct hominid ancestor not shared with the rest of mankind.
