Models show malaria drove African isolation

Researchers looked at data from 74,000 to 5,000 years ago and used advanced models, along with paleoclimate information, to assess ancient malaria risk.
Because people steered clear of these risky zones, communities stayed isolated and didn't mix as much.
This challenges old ideas about how humans spread out and adapted, showing that diseases like malaria were just as important as the environment in shaping who we are today.
