True. So far, Glenn stands pretty much alone, convinced that large scale
morphological change, including parallel adaptations, are demonstrated in what
he assumptively calls the whale "sequence".
I would add to Goodwin's, the words of S. J. Gould:
"The absence of fossil evidence for intermediary stages between major
transitions in organic design, indeed our inability, even in our imagination, to
construct functional intermediates in many cases, has been a persistent and
nagging problem for gradualistic accounts of evolution."
And Eldredge says something particularly apt in this discussion:
"We are faced more with a great leap of faith--that dradual, progressive
adaptive change underlies the general pattern of evolutionary change we see in
the rocks--than any hard evidence."
Leap of faith...lack of hard evidence...
Hmm...
