There is a physics to the size, as well as the shape, of species. See "On Being the Right Size" by J.B.S. Haldane ( _Possible Worlds and other essays 1927).

Got any references Chuck? For others interested in this stuff, "The Self-Made Tapestry" by Philip Ball is a great place to flex your dendrites (too bad the photos are only in b/w)
