The germs that are evolving immunities to our drugs even now, necessitating the development of new drugs to combat them?

This is the one I always point to in arguments like this. I can understand why some people have a hard time wrapping their heads around macro-evolution. The timeframes involved, the misunderstanding that evolution isn't about climbing some sort of ability/capability ladder rather than simply excelling in a niche ("why are there still monkeys?"), etc. It's hard for a lot of lay people to believe when they don't see it happening, even though they believe their magic sky daddy went "hocus pocus" instead.

But, antibiotic resistant bugs? That's something that every patient is aware of. It's the reason why doctors are now real hesitant about prescribing antibiotics. And since the equation is clear - over prescribing antibiotics and patients not fully taking their prescribed regimen leads to more resistant bugs - it shouldn't require much of a leap for them to say "wait... that's evolution! And if it's happening there, maybe it's happening with other things, too!"

Who knew MRSA could be the possible gateway to understanding?
