thanks. lots of good work there (although can't see two of your pictures).
Looks like convergent evolution to me. I knew from cladistic tree that lungfish were off the tetrapod lineage, my point was only that an early foot would look more like a fin than a foot. I have also tracked my old source back and it
was mudskippers and not lungfish I saw ... and that's a hoarse of a different cholera.
They say as you get old that memory is the second thing to go
(and I can't remember what the first was ...)
