I'm trying to find out about Neanderthal vs Cro-Magnon blood types.
as most of us ATSers may already know all primate blood is Rh+, except humans.
Might be a good idea to provide a source for this bit of information.
apparently blood types don't mutate, thus humans must have extra-terrestrial DNA hence why at least 15% of humans are Rh- (it's a recessively
expressed gene, hence the actual presence of Rh- blood cells in our population is closer to a whooping 58%).
Now you need to provide source for at least this "blood types don't mutate" claim, as they clearly do mutate, and thus we don't need to have
so primates are Rh+
humans are Rh-
And this is wrong too. I'm not sure about all other primates, but only some humans (far less than 50%) don't have any Rh antigen on the surface of
their red blood cells.
what factor were Neanderthals?
and what factor were CroMagnons??
Does it really matter whether they had or didn't have some antigen factor on the surface of their red blood cells? All Rhesus monkeys have it. Maybe
all primates apart from some humans have it. What does it matter?
Oh and I'm A-
Oh and looking at distribution of Rh neg blood. It looks to me, like it's a European feature and the tiny fraction you see in other populations is
likely due to gene transfer from European populations into them. Thus, it looks like this feature developed in ancestral European populations only
relatively recently, and thus Neanderthal and Cro-Magnon were likely Rh pos, unless there was parallel evolution which I find unlikely in this case as
Rh neg type does not increase chances of survival in any way.
