    I think we need to be a little careful here. As far as I know, biblical
    literalism (or anything resembling present day YEC) has never been
    an acceptable paradigm in science. It is an injustice to some
    really great scientists of the past (Cuvier, Owen etc) to make this
    type of association.

    I previously mentioned that teleological principles are acceptable
    in science (provided they work). Let me illustrate by giving Cuvier's
    teleological explanation of form and compare it with the principle
    of least action, perhaps the greatest principle of physics.

    Principle of least action:

    Of all the paths that a particle may take between A and B in time t,
    the one actually taken is that which minimizes the action.

    Cuvier's teleological principle:

    Of all the forms which biological structure x might have in environment y,
    the one
    which is actually attained is that which optimizes the function.

     From a scientific point of view, there is nothing wrong with this
    principle. The
    problem is that it doesn't work :). In defense of Cuvier, it was proposed
    at a time
    when few homologies were known. Cuvier was daring enough to predict, based
    on his principle, that few would be found. And the rest is history, so they
    say.

    Most creationists today are not as daring as Cuvier. They talk about re-using
    parts etc. to explain homology. Well, yes, of course, the designer might re-use
    parts. But the point is that the explanatory power of Cuvier's principle is
    lost.

    Can one construct a teleological principle to take the place of Cuvier's.
    Here's one possibility (which I don't actually endorse, BTW :)

    proposed teleological principle:

    Of all the forms which biological structure x might have in environment y,
    the one
    which is actually attained is that which maximizes the reproductive success of
    the genes which encode that structure.
