PAML-Implemented Branch-Site Tests of Positive Selection

Model ln L Parameter Estimates Selected Codons
Anull −679.00 Foreground: p0 = 0.458 (ω0 = 0.0), p1 = 0.542
Background: p0 = 0.458 (ω0 = 0.0), p1 = 0.542
A −673.08* Foreground: p0 = 0.415 (ω0 = 0.0), p1 = 0.573, p2 = 0.012 (ω2 = infinite) 27 (0.99)
Background: p0 = 0.420 (ω0 = 0.0), p1 = 0.580

NOTE.—Models are as discussed in text; parameters are as described in table 1. Foreground branch includes the branch leading to humans, background branches include all other branches of the Hominoidea phylogeny. On the foreground branch in Model A, two classes of selected sites (ω > 1) are possible (as described in Materials and Methods); however, only one class is populated in the present analysis.

*P < 0.05, comparing model A with Anull.
