And the Gods of the Copybook Headings limped up to explain it once more.

You mean tinkering in a blind, sort of accidental way?

Why, of course you do!

Evolution has tinkered … to the point where they can deal with the challenge.  “It’s absolutely beautiful,” she said. “A little bit of tinkering can have a profound effect.”

Really, Ms Whitcomb?  No mention of the steps necessary to get to these tinkered  up variations?  The article goes on to talk about the advantages to carrying young on all fours, and the apparent conflict that scientists have over the advantages or disadvantages of upright bipedal motion.  If carrying young on all fours is more efficient, then why in the world would a blind, accidental process “select” for such an inferior mode of carrying young?

No – None of this explanation is necessary at all,  as long as one approaches this new find with a firm, a priori commitment to Darwinian macro evolution.  Remember, with Darwin, all things are possible, and no links or explanations are necessary, because it must have happened this way, or no way at all.  It just has to appear that way….er..  Isn’t that what Dawkins says about “stupid” people who think life was designed?

The back changes appear to have evolved to overcome the cost of walking on two feet, said Harvard anthropology professor Daniel Lieberman.

The way that scientists talk about evolution sounds more and more like a seeing, intentional process – not a blind, accidental one.  Dawkins would probably cringe at the choice of words used by Katherine Whitcomb here, but then again it was Dawkins who began his famous polemic by stating that “Biology is the study of complicated things that give the appearance of having been designed for a purpose.”

Even the naturalists cannot seem to yank themselves free of from their constant encounters with “tinkering.”
