Evolution and adaptation to different environments seem like straightforward processes. If you treat bacteria to a low dose of antibiotics, chances are they’re going to evolve resistance. But this process isn’t as simple as it seems: different factors determine whether or not those bacteria will develop resistance. Continue reading “Evolution at the edge”
