This was the example I was also thinking about. No amount of theoretical
mathematics can fully account for the intricacies of biological
structures or systems (try predicting the weather more than a few days
in advance - even with a super computer).

This is even more extreme in kangaroos than many other animals. I wonder
whether a similar study into the musculature and skeletal structure of
'roos would predict their phenominal feats of leaping or stamina.

Not so much poor math: I'm sure the math's envolved in the tyrannosaur
paper were pretty good. It's the limitations of mathematics in their
ability to fully describe natural systems that is at fault. Nothing
beats first-hand experiments with actual specimens.
