Re: Did dinosaur wings evolve for breeding display?



I'm not sure Longisquama has any bearing at all; the only possible use of it would be to explore convergent evolution, but since we don't know for sure that the structures actually go to Longisquama, and if they do we aren't sure what they are used for, they really can't tell us anything about the origin of theropod wings.

That's not to say that Longisquama and it's odd (apparent) dermal structures aren't interesting in their own right, they just can't inform us about dinosaur wings when we can't even constrain their presence and distribution, let alone development or function (if any).

There is the _Longisquama_ too...
