>Who says Quarks are mathematical constructs?
I neither clamed it nor denied it. Although I don't follow particle
physics very closely, I believe people were led to look for quarks because
a mathematical model predicted they should exist. So there are certainly
mathematical constructs which predict and in some sense model quarks.
My point was that macroevolution was _not_ a mathematical model -- at least
not in the sense of say Maxwell's equations. Logical construct, yes.
Mathematical model, no.
It was a side issue anyway. Maybe we ought to get back to the main issue,
whatever that was (I know I left it here somewhere...)
