Hadza and Tsimane gut microbiomes share deep ancestry

Original: Similarity in gut microbiome between Hadza hunter-gatherers in Tanzania and Tsimane hunter-horticuturalists in Bolivia s

Researchers are highlighting a similarity in the gut microbiomes of the Hadza hunter-gatherers of Tanzania and the Tsimane hunter-horticulturalists of Bolivia. The overlap in their gut bacteria suggests the two groups share microbial biodiversity inherited from a common ancestry that predates human migrations out of Africa, pointing to a deep shared history carried in the human microbiome across continents.

Why now: New coverage of what gut microbiome similarities between these two isolated groups reveal about pre-migration human ancestry.
