A living animal is never alone. Its body — like yours — is home to trillions of microbes, or tiny single-celled organisms. Those microbes aren’t just hitchhiking. They can play an important role in separating species, researchers now report.

 

That discovery comes from a study on gut microbes in jewel wasps. Seth Bordenstein, a biologist at Vanderbilt University in Nashville, Tenn, led the research. He and coworker Robert Brucker studied what happened when different species of jewel wasps pr...
