And not just to dangling eyeballs waiting to be crushed against the skull, but to eyeballs sitting in a specifically sized socket, lubricated and protected, with muscles attached, again, to the skull to work them.<BR/><BR/>I presume that both in the fossil record and in the development of every craniate (animal with a skull) the eyes, etc, are formed first and the skull is then secreted around it. <BR/><BR/>>And how would the the skull evolve with openings for hearing and olfaction, and a functioning jaw?<BR/><BR/>See above. I don't think that that is the problem.<BR/><BR/>>I presume these were not all components of the first, plated skull, which over time became fused, but do you know if there is actually any good speculation on this? I have found none<BR/><BR/>See above.<BR/><BR/>Stephen E. JonesStephen E. Joneshttps://www.blogger.com/profile/16183223752386599799noreply@blogger.com
