Fruit flies’ microbiomes shape their evolution

The expression “you are what you eat” has taken on new meaning. In an experiment in fruit flies, or Drosophila melanogaster, researchers at the University of Pennsylvania have found that adding different species of microbes to the flies’ food caused populations to diverge genetically, racking up significant genomic changes in just five generations.

“Our work is very suggestive that microbial community composition drives, at least in part, how the organisms in which they live are evolving,” says Paul Schmidt, a biologist at Penn and senior author on the work, which appears in the journal PNAS. “The fact that we can see this effect in experiments done over such a short time scale suggests that the magnitude of the fitness effects the microbes have is incredible.”…
