Claws on Wings

Many people have tried to say that the proof that reptiles evolved into birds is to be found in a fossil bird called Archaeopteryx, which shows claws on its fossilized feathered wings. But all the living birds with claws on their wings are obviously birds! Archaeopteryx and the living ‘clawed’ birds tell us only that some kinds of birds have wing claws and some don’t. Such claws are not something new in birds, and they certainly don’t show that birds with them are any more reptile-like than birds without such claws.
