Genetic analysis indicates that humans arrived in the Americas at least 21,000 years ago, during the last Ice Age. However, the data remains inconclusive and continues to be debated among researchers. The findings challenge previous timelines but require further evidence for confirmation.
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.
