Very interesting #demographic model for historic #African populations reaching back 74,000 years -- that is before ancestors of everyone today began moving out of Africa. This factors in #malaria risk as contributing to movements and success of populations. Even that long ago, even with #huntergatherers.
"Our results show that humans strongly avoided or were unsuccessful in potential malaria hotspots. The effects of these choices shaped human demography for the last 74 kya, and likely much earlier, by fragmenting human societies over time and contributing to the formation of modern population structure."
