Percent frequency distribution of the size and inclination of the metacone in Siwalik murine rodents.
Species that are likely in ancestor-descendant relationships10,33 are connected by a solid line. Open symbols correspond to those in Fig. 1A and colors of the ‘size and inclination’ legend correspond to those in Fig. 4. Different from the previous phylogenetic hypothesis (Fig. 1A), Progonomys hussaini is interpreted to appear after the initiation of lineage separation34. See Tables S1–S3 for numeric percentages and the number of individuals observed in this study and SI Discussion for age determination. All localities but DP 13 have Y as a prefix.
