Ancestral state reconstruction is a powerful tool for testing theories of the order and timing of character evolution (Maddison, 1994, 1995; Yang et al., 1995; Schluter et al., 1997; Cunningham et al., 1998). Reconstruction methods that include explicit information both on the relative probabilities of change and the opportunity for change now exist for molecular sequences and amino acids (Yang et al., 1995; Koshi and Goldstein, 1996) and for both multistate discrete and continuous data (Martins, 1994, 1999; Schluter, 1995; Schluter et al., 1997; Pagel, 1997, 1999, personal communication; Mooers and Schluter, 1999). These latter model-based methods have been utilized successfully in ecological and evolutionary studies (see, e.g., Ryan and Rand, 1999; Hoekstra and Edwards, 2000; Morales, 2000; Matyjasiak et al., 2000; Oakley and Cunningham, 2002; Berendonk et
