Study Suggests Gut Microbiomes Tracked Human Migration Across Continents

Published

Just the facts

New scientific research published by NPR highlights surprising similarities between the gut microbiomes of hunter-gatherers in Tanzania, such as the Hadza people, and horticulturalists in Bolivia, such as the Tsimane people. The study suggests that symbiotic gut bacteria co-evolved and traveled alongside migrating human populations across continents over thousands of years. Scientists are examining the specific role these ancient microbial communities play in human metabolic health, immunity, and overall longevity. Understanding these baseline microbiomes offers critical insights into how modern diets and industrialized lifestyles impact human health and microbiome diversity.

Why this is news

Researchers released a new scientific study investigating the evolutionary history of human gut microbes by comparing traditional populations across different continents.
