The Evolution of Rh- Blood

Here is my original blog post from February 6th 2015:

7 Regions with more than 20% Rh Negatives

Is it true that the Mayans and Incas have high levels of Rh- blood?

Mexican Indians (Maya and Aztec): 0% Rh negative

Scientists no longer use the term Cro-Magnon.

There are no studies showing their blood type frequencies either.

No evidence of rh negative blood in Cro-Magnons

Neanderthals were Partial D.

Neanderthals found to be Partial RhD (not RhD-)

Rh negative means that the D antigen of the Rhesus Blood Group System is absent.

What does it mean to be rhesus negative?

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).

Did Neanderthals “become” Rh negative?

If you have additional information, share it below or tag me on X:

Rh- men seem to be drawn to strong women and the concept of "feeling threatened by strong women" is foreign to us.

We seek teamwork in relationships and don't need to be "the boss at home".

We are competitive with other men, but not with women and children.
