Scientists no longer use the term Cro-Magnon. There are no studies showing their blood type frequencies either. Neanderthals were Partial D. Rh negative means that the D antigen of the Rhesus Blood Group System is absent. Partial D may have been an evolutionary stepping stone from testing positive for the presence of D (Rh+) to a complete D gene deletion (Rh- or D negative).
