This claim is spread yet I have yet to see a single study supporting it. Cro-Magnons were also not a species. They were likely hybrids in which case I always go back to the species included in their genetic ancestries looking for the ones in which Rh negative blood was most frequent. I do the same with any nation or population where different genetic ancestries came together to figure which may be responsible for Rh- blood being frequent. I cannot really understand the reason for the popularity of this theory and why so many mindlessly spread what borderlines propaganda unless they do not want to be associated with Neanderthal ancestry.
