How come when there are countless DNA mutations, most of them are lethal, some of them peculiar but none will grant us actual super powers?

answers:
livi say: Mutations like being born with an extra finger are understandable and totally plausible because the human body already has all the genetic code needed to create a finger. It just messed up somewhere and produced one too many. Being born with wings or ice powers (or something like that) is a whole different story. For any of these to happen, it would take a LOT of different mutations occurring, all at the same time, which is as close to impossible as it gets. I guess since birds have wings it's not completely impossible for humans to eventually develop them too. But this would take millions of years. A major component of evolution is also natural selection, where the DNA mutations that are helpful make the organism more likely to survive and therefore reproduce more, spreading the mutation. Tiny mutations along the way that would be needed to create superpowers wouldn't be inherently useful and therefore wouldn't stick to the main parts of human code. There are just really bad chances of any mutation turning into superpowers, unfortunately ):
-
Smeghead say: Because DNA is a chemical, not magic.
-
Donut Tim say: Because the mutations are random.
-
MARK say: Because superpowers are only found in works of fiction. They are not real and are irrelevant to biology.
