Did we ever find a fossil for human with wings? during evolution we should find
creatures that don't look well and failed to reproduce, where are these creatures
that failed during evolution, such as finding creatures with one leg.
It really is difficult to know where to start when somebody packs so much misunderstanding into so few words.
Firstly, sprouting wings is not something that is going to happen in a single step and then fail. Changes that failed, just like individual changes that succeeded, would be relatively small and probably not easily recognised in a fossil. Changes that you can easily identify are going to be the accumulation of a number of small, successful ones.
Secondly, fossilisation is an incredibly rare event. The chances of catching an individual with a failed change (which would, by definition, not last long in the population) would be tiny.
Thirdly, every extinct species is actually a change that ultimately failed.
