Do most evolved animals have different blood types?
Is it an evolutionary benefit to have multiple blood types in each species?
Or is it just an anomaly with neither negative or positive benefits towards the hosts survival.
I don't have the first clue about what kind of evolutionary advantage having different blood types imparts on an animal, but I know that different animals have different blood types - in other words, animals don't just have the ABO system for their own blood.
And that's officially as much as I know.
