Analyses of proximal phalanx indices.

Results of ANOVAs (F-statistic) and Kruskal-Wallis tests (H-statistic) among extant proximal phalanx indices and t-tests comparing those of Notharctus tenebrosus (AMNH 143612/143640) and Darwinius to extant primate groups. See results for post hoc comparisons between extant groups. For the fossil analyses, the smallest absolute t-value indicates which extant group the fossil is most similar to. Comparisons are considered significant at the Bonferroni adjusted alpha of 0.025.*F and H statistics are highly significant for all comparisons (p
