Perspectives

EVOLUTION:
Climb Every Mountain?

Santiago F. Elena and Rafael Sanjuán

Evolutionary biologists have long argued that adaptation to a particular environmental niche should constrain a population's ability to survive in other niches. In their Perspective, Elena and Sanjuán discuss new evolution experiments with populations of the bacterium Pseudomonas fluorescens (Buckling et al.). These experiments provide evidence that as a bacterial population becomes a niche specialist, it is less able to adapt to other niches.
