It is well known that sickle cell anemia provides resistance to malaria. The price paid for that resistance is certain death. Sickle cell anemia is fatal in 100% of affected individuals. So if the sickle cell anemia will certainly kill you, what good is malaria resistance? This is a classic case of what happens as a result of mutations. Mutations screw things up. This mutation results in death to the individual.


Do you know of any predictable mutations that enhance the individual?
