I'm actually studying for a class and there are actually 30 antigens involving blood type. Biologically we are ONE human race, but blood types make no sense whatsoever. Science explains blood types through antigens but what's with the variation? What's with the fetal incompatibility? It's so strange it just screams aliens.
