Well I didnt say she's perfect lol. Trees are just a great example of how evolution has done a pretty good gob on a specific trait. Now compared to how long humans have been around and our constant changing environments and diet, medicine and other advancements keeping us alive, trees have had quite a head start for getting stuff "right"! But yes intelligent design is garbage. But what happens if we design an intelligent race and set it loose on another planet and they start doing stuff they weren't designed to do? lol. Bad designer or stupid creatures? I'm just having fun here...

Actually the "technology" behind wisdom teeth is quite smart. How many organisms feature resources timed to "spring" 20 or 30 years from birth, to replace lost "components"?

You experience them as painful because your teeth don't rot as they used to; until the XX century, it was common for people to lose many of their teeth by the age of 30, so they were grateful for an extra set. They'd probably be dead before 45 anyway, so just a few would suffice to chew your way through the last years of your life.
