Table 3. Posterior probabilities of group membership based on the bgPC scores for fossil specimens in the analysis based on the anthropoid sample.

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. Highest probability for each specimen in bold.
