On the other hand, Chris Bennett is of the opinion that the evidence is

Unwin and others seem to prefer a broadwing with the trailing edge running
directly from the wingtip to the ankle.

If the evidence is so 'overwhelming', I don't know why these guys don't send 
just _one_ sample to shut me up. I am ready to be converted! And it's that easy.

On the other hand, in Peters 2002, I showed that when you open a wing finger 
with membrane preservation, you can't get a broad membrane from the narrow 
evidence available. Sordes included.
