Type A was around before the B and O versions popped up in humans, gorillas and baboons.
It’s also thought that those with Types A and B might have inherited them from a single ancestor millions of years ago.
Why do we care? Blood types make you vulnerable to disease. Type Os catch cholera, plague and other diseases more than others. Type As get smallpox.
People with Type A are prone to blood clots which allowed them to survive during childbirth and after they suffered traumatic wounds.
Does blood type have anything to do with the diet that’s best for us? An interesting book called Eating Right for Your Type by Peter D’Adamo thinks so and his ideas make sense. Maybe it’s your answer, too.
I am Type O negative which I thought was odd because I'm such a "positive" person. Haha! No correlation. However, in my group of pals, whenever anybody needs blood, they come looking for me. I'm a universal donor and a fairly rare blood type. Only 7% of the population has it. Lucky ducky me!
