Rapid genetic adaptation to environmental change, or evolutionary rescue, can be constrained by a less adaptable mutualistic partner. Here, the authors explore evolutionary rescue in an obligate mutualism between crossfeeding E. coli strains, finding that stress can lead to mutualism breakdown through the reversion to autonomy of one partner.
