Make it a good one.

  • How much power do I have?

    If I could divert the asteroid that resulted in the K-T event, that’d drastically change history. It may not have stopped dinosaurs from eventually going extinct, but it’d have given them 33 million more years more to evolve, and would certainly have affected mammalian evolutionary history. Maybe, just maybe, raptors would have gotten smart enough.

    Ooh! Take back a lot of ravens. They’re almost smart enough already. Heck, I wonder if taking ravens back even earlier would be enough for them to evolve into something dominant. Problem is, they’re not particularly social, and I think that’s been our greatest advantage.

    Or: introduce modern octopus to ancient oceans.

    Stopping the K-T event is my favorite, though. It would absolutely have changed how life on Earth has evolved since.

    30M years between extinction events is about all you get, though.
