From generalized tracks to ocean basins - how useful is panbiogeography?

In 1993, in a brief review of different methods of analyzing patterns of distribution (Cox & Moore, 1993), I commented upon the methodology of panbiogeography. These comments were later criticized by Grehan (1994). In writing a reply to Grehan, I found that it was necessary to construct a wider analysis and review of panbiogeography, so that my original comments, as well as Grehan's criticisms, can be seen in the context of Croizat's original views as well as in that of the more recent elaboration of his theory by Grehan and others.
