From an evolutionary perspective, why do we have multiple different blood types and what advantages or disadvantages does that entail?
That's interesting. Are there any theories on how different blood types evolved in humans?
One theory is that different blood types evolved as a response to immunological challenges, such as pathogens or parasites, in different regions of the world. Additionally, some scientists believe that blood types may have evolved as a way to allow individuals to adapt to different diets.
