I'm not big into the evo debate, but I feel compelled to point out that adaptation and evolution are two different things. We develop immunities all the time, that does not mean we've evolved into something we weren't last year.

But this pathogen doesn't have an adapting immune system. Its DNA has genuinely mutated, turning it into a resistant strain. That's evolution.

Uh, you might want to brush up on your science a little. Strains are not mutations. They coexist with other strains and become dominant when the other strains are killed off. That's pretty much the definition of "strain." If something had mutated they would be talking about mutated variations, not strains.
