That is valid. I considered species would likely go extinct before a notable mutation would show up. The only exception might be if a species were already heading in a certain direction genetically for the last ‘X’ million years maybe it would accelerate. I’ve seen or heard several different things that made me start toying with the idea… orangutans using a spear to fish, deer behaving differently in more highly hunted areas over several generations, orcas learning to bait birds with regurgitated fish. There is still a huge gap before reasoning though.
