Hadza and Tsimane gut microbiomes point to shared ancient ancestry
Original: Similarity in gut microbiome between Hadza hunter-gatherers in Tanzania and Tsimane hunter-horticuturalists in Bolivia s
Researchers are highlighting striking similarity between the gut microbiomes of the Hadza hunter-gatherers of Tanzania and the Tsimane hunter-horticulturalists of Bolivia. The parallel suggests both populations carry microbial lineages inherited from a deep ancestral human past, preceding the migrations that separated their ancestors across continents. Commenters in anthropology circles say the finding could reshape understanding of how human gut biodiversity evolved and why industrialised populations have lost much of it.
Why now: The finding offers rare genetic-era evidence tying modern indigenous microbiomes to human migrations out of Africa, a topic of active scientific debate.
