Abstract
How does genetic background influence a population's evolutionary response to an environmental change? Which traits are selected for and how quickly does the population adapt? Filipow et al. (2024) address these questions by exploiting the natural genetic variation of Pseudomonas aeruginosa, a bacterium often found in the lungs of cystic fibrosis patients. They find that while genetic background influences the rate of phenotypic evolution, it does not alter the evolutionary outcome. Their findings contribute to a growing body of work that connects genetic background to future evolvability.
