It turns out that a lot of implications can be drawn from the mammalian knee-joint. It appears that the organ is a four-bar linkage, and is irreducibly a four-bar linkage. That means that a knee, for us hairy quadrapeds or bipeds, could never have started out as a simpler system -- say, with three or two bars.
The good professor, Stuart Burgess, goes on to say that he's seen quite a lot of irreducible complexity both as an engineer, and as an observer of nature. Irreducible complexity, he says, requires an immense amount of intelligence to design.
I would like to see the torrent of comments that will, of a necessity, flood the Independent's e-mailboxes. The whole issue of "design" has turned into a Bic lighter in a sea of gasoline, where the opposition seems a lot more certain that Design must necessarily entail Creationism, and if they can ever get themselves to ignore the matter, like those religious gents tried to ignore Galileo's findings, then maybe they can make God just go away.
Thanks to David Mills at Touchstone for the idea.
