If you're going to answer questions, then answer them instead of giving too-cute "hint" nonsense to let everyone know how smart you are

Asking why we don't have wings or infrared vision isn't the same because there was never a point along our known evolutionary chain where we DID have wings. So while it might be handy to have wings or six arms or acid breath, it's not the same as asking why we went from a trait we used to have (claws) and adapted to have a different trait (nails) instead as our primate ancestors evolved.
