Natural selection is an occurrence in nature in which organisms with genes that have mutated to adapt to certain ailments, survive better than their mates. J.B.S Haldane made a hypothesis that this phenomenon of natural selection accounted for why people in Africa had developed resistance to malaria. Their hemoglobin, proteins, and other compounds that are necessary for the function of the red blood cells had been modified so that they would not easily be infiltrated by malaria parasites.
A.C. Allison confirmed this in his experiment which showed that people who had sickle cell mutations in the gene, beta hemoglobin were mostly found in regions where malaria was prevalent. Their genes had also been modified such that they were resistant to malaria.
