Could the numbers also be influenced, literally, by survivorship bias? Those that survived malaria likely had a genetic advantage that they passed along, while those that didn't died. Malaria may have far less impact today than in the past.

At least one such genetic advantage has already been identified: the gene mutation that causes Sickle Cell Anemia when present as two copies conveys malaria resistance as a singleton. In areas where malaria is endemic, it would be selected for.
