A vast microbiome, double our own, exists in the Yanomami people, who have been isolated in the Venezuelan Amazon for 11,000 years. A study of skin, fecal and oral samples from 34 tribal members was published in Science Advances in 2015. Researchers analyzed the samples, finding more than double the number of genes than the average US person. It has long been thought that the western diet, antibiotics and hygienic practices have impacted the modern microbiome but studies like this give us a window into what our microbiome might have been like in bygone eras.
