New Insights Into Gut Bacteria Changes Could Impact GI-Related Research
gut bacteriaA new study entitled “Rapid changes in the gut microbiome during human evolution” describes how the human microbiome has been changing since the human–chimpanzee split. The study was published in the early edition of PNAS. The findings could have implications into developing therapies for GI-related diseases that leverage the use of and properly balance bacteria in the gut. In order to understand how the human microbiome evolved, the authors sequenced the communities of microorganisms found in the gut of chimpanzees, bonobos, and gorillas, and reconstructed a phylogenetic tree to determine how the present microbiomes of humans diverged from these ancestors. As human samples, the authors collected microbiome samples from population groups in several U.S. cities, rural towns in Malawi, and pre-industrial villages in Venezuela. They found that humans' microbiome evolved at an accelerated rate, but are much less diverse when compared to apes. The shift in composition was directed towards an increase in Bacteroides, which help in digesting diets rich in animal protein and fat, thus indicating a microbiome evolving towards a specialized animal-based diet. Accordingly, the presences of Methanobrevibacter and Fibrobacter, which contribute for digestion
