A groundbreaking study has revealed how Kenya’s Turkana people genetically adapted over millennia to survive in one of the world’s most challenging environments. Researchers identified key genetic variants, particularly in the STC1 gene linked to kidney function, that help the Turkana process a meat- and blood-rich diet and cope with severe dehydration. This evolutionary adaptation emerged around 5,000 years ago as northern Africa grew more arid, allowing the Turkana to thrive where resources are scarce. However, these same protective genes may now pose health risks as some community members move to urban areas, creating a mismatch between their ancient genetics and modern lifestyles. Despite this, the research highlights the incredible resilience of human evolution and offers valuable insights for public health strategies in a rapidly changing world.
