Blood Grouping Among the “Blackfeet” and “Blood” Tribes of American Indians

[摘要] Although various tribes of American Indians have consistently been reported as belonging primarily to group O, the Blackfeet and Blood tribes appear to be an exception, showing as high a percentage of group A as other tribes show of group O. This may be seen by comparing tables 2 and 3, with 1 and 4.These results suggest the necessity for reconsidering the origin of the American Indian.
