It’s a standing joke that creationists demand a complete time-lapse recording of evolution before they’re going to believe it. Joke no more: we’ve got one. It’s a movie of bacteria evolving antibiotic resistance. I don’t even need to explain it, because the video explains everything that’s going on.
Different old joke now: But they’re still just bacteria
.
Also, you should be horrified by the power of evolution. It took 11 days for the bacterial population to evolve resistance to a lethal, thousand-fold increase in antibiotic concentration.
