W.R.,

I read awhile back that sickle cell anemia was a genetic progression in Africa amongst some to ward off malaria.

So, I did a quick google search to test my memory...

"Two genetic conditions--sickle cell trait and a mild version of the blood disorder known as thalassemia--that by themselves give millions of Africans natural protection against malaria, can be rendered essentially useless when they occur together, according to a new study of Kenyan children that is to be discussed today at the Fourth Multilateral Initiative on Malaria Pan-African Malaria Conference in Yaound?Cameroon.

"We've looked at these traits individually and we expected that if people had both of them, they would be really protected," said Tom Williams, a Wellcome Senior Research Fellow at the Kenya Medical Research Institute (KEMRI) and the study's lead author. "But it turns out that when you start combining the two, you can lose the effect of both."
