It's not really that the race is more susceptible to sickle cell anemia,
it's a defese created due to the factors of the environment, which is now
genetic. The sickle cell gene provides some protection against malaria. So
in areas where malaria is common, evolution decided the protection it
provides against malaria offsets the damage done my sickle cell anemia.
