You're right about finch beaks, that's directional selection. But the real lesson is about DDT and mosquitoes—that was *man-made* selection, and it backfired when the resistant ones survived. My cousin lost his entire mango crop to pests that the spraying made stronger. So while nature has its types, I've seen how our clumsy hands can force a change that leaves us worse off.
