If You're Healthy, Maybe Thank The Neanderthals
I suspect that "hybrid vigor" went both ways. Human/Neanderthal offspring would be resistant to diseases from both northern climates to which Neanderthals were native and diseases brought in from human migrants from African. I also suspect that diseases brought in from the African migrants would have played a major role in wiping out the Neanderthals (as it did against Native populations in the Americas, for example).
