In my anthropology class my teacher said Europeans primarily have type A blood, blacks primarily have type B, and asians primarily have type O. I then later read an article that said type O is the most common for everyone. Who is right, the teacher or the article? This is not true.    Blacks and aborginals primarily have O  Europeans have A  East-Asians have A and B  South-East Asians have O as well.    You might want to read this:  http://www.bloodbook.com/world-abo.html      2508
