Thread says open to all and so seeing if this works. You commented:
I know that the fossil record for marine invertebrates IS complete
This comment seems way over the top. A "complete" fossil record would at a minimum mean every transition of evolutionary change would be visible. This is, of course, not even remotely true. I doubt you can present even small continuum of evolutionary change, say species A evolving into species B and then into C and into D, etc,...and leading to major morphological and genetic change.
For a minute, I thought you were making an Obama post.....thanks for the welcome back.
Well, if you can, please do. Let's see the species to species transitions leading to new genera in any posited evolutionary sequence, as a small starter. It'd be better to show that continue to new, major morphological change and families of species.
