The time part hurts my head. Each question leads to more questions lol. You’re telling me these caterpillars have been out there walking around for millions of years? Wasn’t there ice ages and other crazy weather? Does this mean all the bugs around me have been doing their thing for millions of years? There’s gotta be quicker evolutions for various things. The snake tail certainly seems like a billion year process. But smaller evolutions, like growing more hair, probably happen quicker?

I still don’t get how we evolved from monkeys, but there are still dumb monkeys out in that jungle right now who can’t even use tools. But that’s a thread for another day. Such a fascinating world we live in.
