Oh, yes..... one more thing on the subject of evolution. Many published studies over recent years have shown that chimpanzees mostly have Blood type A, almost no Blood type O, but never Blood type B. The other great ape, the gorilla has Blood type B, almost no Blood type O, but never Blood type A. In these 'man-apes' species, said to be the ancestors of man, there is NO Blood type AB in either. Generally speaking, man has both Blood types A and B, and Blood type AB. Blood type O, in man is by far the most common in virtually every racial group.
