I have been looking into this for years but do need more data on it.
So far I have the following:
O Positive
All indications show Africa as the source.
A Positive
Usually people say Europe, but Armenia and Assyria show up also high in A positive blood. Assyria is high for A2 which
also Tutankhamun had. So the jury is out on this one, but I actually tend to look at the Fertile Crescent as a potential
point of origin. And then the Andaman Islanders and Blackfoot Indians appear to be the highest in A positive blood.
B Positive
The Himalaya region seems very high. And likely is the point of origin. It is also interesting that most native
American tribes are 100 percent O positive, yet the Inuits have significant B positive frequencies as well.
And the Inuits replaced the original Proto-Eskimos around 1,000 years ago which were likely blood type O.
B is likely the newest of the alleles creating the AB later than that. The fact that AB is the newest blood type
shows a strong likelihood that in fact blood type B came after O and A.
AB Positive
This one is a puzzle as it came when the first B mixed with an A. What is interesting is a study of 55 ancient Hebrew
remains where more than half turned out blood type AB. Positive or negative has not been indicated in the study:
Blood types of the ancient Hebrews
O Negative
It seems that wherever rh negative blood is high, so is blood type O. Be it amongst the Celts, the Basques or the Rhone Valley Walsers. Looking back in time, Sumer might be the place of origin. But more studies are needed as we only have indications at this point.

A Negative
Here we go again: Is it Armenia, Assyria or Europe. Or did O negative tribes with Sumerian ancestry simply make it to Europe and mix with
A positive Europeans to produce A negative blood?
B Negative
Since the original blood type B people from the Nepal region were likely all B positive, there is not doubt that B negative blood
first came up when a B positive person had a child with an O negative one.
AB Negative
Again, a blood type A and blood type B person mixing with both carrying the D negative at least recessively was when the first person with AB negative blood was created. Where? You tell me!
