What's phenomenal outside the research is that they've created the conditions to present their experiment in a way that's accessible to someone who didn't, say, graduate from Harvard. They dyed the agar jelly black to make the bacteria visible and heated the lid of the petri dish to keep it dry and free of condensation, among other moves with an eye on the cinematic effect of the experiment. Those efforts make it easy to see evolution at work, even for those who might think science is something you "buy into."
"Seeing the bacteria spread for the first time was a thrill," said senior study investigator Roy Kishony. "Our MEGA-plate takes complex, often obscure, concepts in evolution, such as mutation selection, lineages, parallel evolution and clonal interference, and provides a visual seeing-is-believing demonstration of these otherwise vague ideas. It’s also a powerful illustration of how easy it is for bacteria to become resistant to antibiotics.”
