Table 4. Posterior probabilities of group membership based on the bgPC scores for fossil specimens in the analysis restricted to hominoid genera.

Note that these are probability estimates of having a particular score given membership in a particular group, not the likelihood of group membership in each of a priori defined groups given a particular score. The highest probability for each specimen in bold.
