GoKawiilStudy finds gut microbes shared by Hadza and Tsimane trace ancient human migrations
Researchers led by Carter et al., writing in Nature, compared gut microbiota of Tanzania's Hadza people with Bolivia's Tsimane people, whose ancestors diverged tens of thousands of years ago. They found hundreds of microbial species common to both groups, with genetic differences between strains aligning with the timing of prehistoric human migrations. Many of these shared microbes are now rare or absent in people living in industrialized regions.
