Everyone knows that bacteria are getting more immune to antibiotics. Now, some bacteria have been discovered using a new trick, taking folates directly from their host if a medicine blocks them from producing their own.
Bacteria are very good sources of proof to the theory of evolution. They continue to evolve and adapt to the environment in which they are present. It comes as little surprise to me that this happens.
Nor am I surprised. As you say, they prove/personify evolution.
