The scientist who first connected sickle‑cell anemia with increased survival from malaria was Anthony C. Allison.

Quick Scoop

  • In the 1950s, British-Kenyan scientist Anthony C. Allison studied populations in East Africa and noticed that people carrying one sickle‑cell gene (the HbAS heterozygous state) were less likely to die from severe malaria.
  • His work provided classic evidence of natural selection in humans: the sickle‑cell trait is harmful in the homozygous state (sickle‑cell disease) but offers a survival advantage against malaria when present in just one copy.

This connection between sickle‑cell trait and malaria resistance is now a textbook example of how genetic variants can persist in human populations because they confer an advantage in a specific environment.
