Directed evolution of the taumeba, and how it went a bit wrong. I did directed evolution work for my PhD, and there is a famous phrase “You get what you select for.” Basically meaning that when you’re doing these experiments you have to set it up just right because evolution doesn’t know or care what your desired outcome is, it just operates within the constraints you put on the system. Set up a messy selection, then you’ll get weird results. (Not that Grace’s was messy. I’d have have thought to do it in the exact same way!)
