Dinosaur to bird? It would be a bad leg long before it would be a good wing.

Please explain. (This is actually sort of true though. Sorta like bat and flying mammal legs aren't so great for running, but the membranes between their crazily long fingers make a decent - but not perfect - wing.)

OK

I believe Darwin’s theory on natural selection goes something like this: A beneficial genetic mutation, which increases the chances of survival, is kept in the DNA and passed on. A genetic mutation that was not beneficial would lessen the chances of survival thereby increasing the possibility the non-beneficial DNA mutation was not passd along.
A species in transistion to another species, such as dinosaur to bird, would have to have incremental changes made to it’s DNA to transform the leg into a wing. I am saying the leg would become a non-beneficial genetic change during it’s transition long before it became a beneficial genetic change, a wing.
These are my thoughts. I am open to intelligent arguments disputing my thoughts. It will give me reason to study further.
