Created for a blog post for Jamie Halls awesome paper on the impact of species interactions alter evolution to a niche. He showed that while our favourite (white) bacteria evolving alone break a costly cellular pump, the presence of another (green) bacteria they don't. In his blog post Jamie compares this with the a couple of examples of where this has been seen in 'big' animals like the finches in the Galapagos. But unlike the decades it takes for this to been observed, in bacteria these changes can be seen (and tested) over just a few weeks
