What specific biological factor, identified in a recent study, might have contributed to the extinction of Neanderthals?

A recent study suggests that blood group incompatibility between Neanderthals and modern humans may have contributed to Neanderthal extinction. Researchers found Neanderthals possessed a unique Rh factor, resulting in a high risk of neonatal hemolytic disease in offspring from interbreeding with other hominins, potentially causing death.
