ABO Blood Type distribution map shows little similarity between east Asian peoples and North American native populations

The world maps of ABO Blood Type distribution in the world on the Contactee Blood Types Study by ICAR website shows the incidence of the A, B, and O blood types in indigenous populations. 

For example, do you know that the indigenous peoples of Central and South America are entirely Blood Type O? But there are hardly any Type Os in Eastern Asia. Therefore, it does not seem logical than the people of Central and South America could be descended from the those of Eastern Asia who crossed the Bering land bridge during the Ice Ages. Could this mean that, as some mystics and psychics proclaim, that First Nations people on the west coast of North America actually come from Lemuria?
