Gut microbiota codiversified with their hosts: new preprint

Ever wonder if H. pylori was the only gut microbe that tracked human population as they migrated out of Africa? Here we show evidence that others did too! By matching human genotype data to gut metagenome data, Taichi Suzuki, Liam Fiztstevens and co-authors identify a set of mostly Firmicutes that transferred between related people over thousands of generations.
