Neanderthals
Autism is more prevalent among whites and especially among red-haired people. A theory that explains this is whites have Neanderthal ancestry.
While I don't have red hair (blond with a reddish beard), there are several red-haired people my family, I had freckles when young plus fair skin, and also had ADD (long before the scourge of Ritalin). I also have a lot of Celtic ancestry -- and the most redheads are in Ireland and Scotland. Not surprisingly, the Celts have always been considered the most fierce fighters in the world.
