Dear Joe,
I don't know if you are familiar with the statistics software R, but
there is a package for it called "geiger" that has functions to test for
possible models of character evolution across a given phylogeny,
including stasis, Brownian, Ornstein-Uhlenbeck, and trended. Perhaps you
could check it out?
kind regards,
Manabu

Dear morphmet,
I have a 3D dataset where I have been comparing morphology and phylogeny
at family level (suiforms). Specifically I have generated a phenogram
(based on procrustes distances) to compare and contrast with the family
phylogeny. The phenogram is lacking in some sub-species but has
representatives for the genus we are examining (the suids, the phylogeny
also uses Hippopotamus and Peccary as outgroups which we do not have).
I have genetically divergent but morphologically similar populations;
based on prior knowledge of species history, habitat and diet homoplasy
is deemed unlikely and as such I wish to test the dataset for stasis.
I was wondering if anyone knows of methods by which I could assess
stasis based on congruence between morphological and genetic
relationships, or point me in the direction of papers where this has
been done.
Thanks in advance
Joe
