This is a classic example of how people are brainwashed into believing macro-evolution is true. Whether intentional or just out of ignorance, that’s a different matter. What’s happening in this article is selection: the cockroaches that already had the ability to resist expressed in their genome survive and pass it on to the next generation. Hence we end up with only cockroaches that have that ability expressed. However, the ability wasn’t “evolved”, meaning it did not “appear out of nowhere”. It was in the genome already. It’s only proven advantageous in a particular setting, so to favour the survival of those that had it expressed. The cockroaches are still cockroaches and such they will remain.
