Results of phylogenetic analyses. Only simplified high-level trees of strict consensus are presented here, showing the main dichotomies among higher taxonomic primate groups (see supporting information). (A) Strict consensus of two equally most-parsimonious trees of 2,810 steps each [consistency index (CI) = 0.273; retention index (RI) = 0.53] obtained from heuristic searches performed on the dataset including some ordered multistate characters (Option 1). (B) Strict consensus of 38 equally most-parsimonious trees of 2,646 steps each (CI = 0.289; RI = 0.51) obtained from heuristic searches made on the same dataset but considering all characters unordered (Option 2).
