Maybe the professor was so dumbfounded he stormed out of the room, quitting forever

I mean Rocks aren't living. Therefore, they don't produce things like glucose like a plant, and they don't eat other animals to have nutrients. So they aren't in the food chain, and subsequently don't have any predators or the possibility of starving. Therefore, they wouldn't need to evolve. I know this is a shitpost, but I figured SOMEONE would buy this lmao

But you get what I'm saying right. Even if it is a copypasra from many years ago, the prof may have lost a lot of IQ points that day.
