Archaic Human

Caption

In saliva, scientists have found hints that a "ghost" species of archaic human may have contributed genetic material to ancestors of people living in Sub-Saharan Africa today. The finding comes from a University at Buffalo-led research project that examined the evolutionary history of MUC7, a gene that codes for an important salivary protein of the same name.
