Most Of The Microbes In Your Gut Probably Came From Your Parents

Trillions of bacteria call the human gut home. The bugs affect not only our digestion but our hormones and immune systems, too. Now researchers show most of the microbes that colonize mammals’ guts pass down from generation to generation. The few that don’t tend to be the kind that makes us sick. The discovery suggests pathogens evolved to spread between individuals instead of through inheritance.Generation to Generation
