My father had type O, he was the calmest unfrizzled individual I ever knew, nothing upset him. Only time I saw him upset when he learned his mother died.

It is odd to me that my family history is all european going back centuries, but we are all O+ blood types. No A or B or ABs.

Great video. Once more, you put together solid data from a range of disciplines into s excellent narrative. Thank you. [Even as an evolutionary biologist, I learned a number of new pieces to add to how environment, founder sources an balancing selection have worked on humanity.]

This is unprofessional. Doctors know that there are many more blood types than the ABO and Rh systems. We have known this since WW2
