RH Negative Blood: Evolution Should Have Erased This Blood Type. It Never Happened.

There is a blood type that should not exist. For thousands of years it turned mothers against their own unborn children — and by every rule that governs evolution, a trait that does that kind of harm is supposed to vanish. This one didn't. More than half a billion people carry it today. This is the story of Rh-negative blood, told from the surface all the way down: past the alien theories and the chosen-bloodline myths, through the real discovery that split humanity in two, through a century of unexplained grief that came before modern medicine had an answer, and down to the strange mechanism that may explain why this "impossible" blood survived after all. Settle in. This one is long, and it is meant to be. Whether you are here to follow a genuine scientific mystery as far as the evidence will take you, or simply to let the story carry you toward sleep, there is no need to hurry tonight.
