Kolmogorov-Smirnov tests comparing distributions of number of species in the phylogenetic analyses and number of species sampled in a morphogenus

Species	Mean species in analysis	Mean species in genus
Mammalia
Monophyletic	41.2	5.1
Nonmonophyletic	37.4	5.7
2-tailed P	0.524	0.029
Mollusca
Monophyletic	80.5	5.8
Nonmonophyletic	45.9	7.0
2-tailed P	0.002	0.712

Two-tailed P values and mean values for monophyletic and nonmonophyletic genera are given for Mammalia and Mollusca.
