Gut microbes migrated worldwide alongside prehistoric humans
Original: Prehistoric global migration of vanishing gut microbes with humans
New research shows that some human gut microbes co-migrated with prehistoric human populations as they spread across the globe, and that strains of these bacteria have since vanished from people in industrialised countries. The findings, published in Nature, suggest the microbiome preserves a record of ancient human migration routes, and that modern lifestyles may have cost us microbial diversity carried by our ancestors for tens of thousands of years.
Why now: A new Nature study linking gut bacteria diversity to ancient human migration is drawing attention for what it reveals about microbes lost in industrialised populations.
