Can the Bacteria in Your Gut Explain Your Mood? - The New York Times
Biologists now believe that much of what makes us human depends on microbial activity. The two million unique bacterial genes found in each human #microbiome can make the 23,000 genes in our cells seem paltry, almost negligible, by comparison. ‘‘It has enormous implications for the sense of self,’’ Tom Insel, the director of the National Institute of Mental Health, told me. ‘‘We are, at least from the standpoint of DNA, more microbial than human. That’s a phenomenal insight and one that we have to take seriously when we think about human development.’’
