Malaria Didn’t Cripple Africa’s Early Growth? The Genetic Evidence That Shocks

Emilio Depetris-Chauvin, David N. Weil

Think malaria held back Africa’s early development? Think again. This video dives into a groundbreaking study by Emilio Depetris-Chauvin and David N. Weil that uses the sickle cell trait as a genetic time capsule to measure historical malaria death rates. The shocking finding: despite killing up to 10% of children, malaria had almost no measurable impact on population density, urbanization, or political complexity in pre-colonial Africa. We break down the counterintuitive economics—why infant deaths didn’t derail growth—and reveal how human genetics rewrite history. If you’re into data, history, or mind-bending social science, this one’s for you.
