Figure 8 in Dental polymorphisms in Crocidura (Soricomorpha: Soricidae) and evolutionary diversification of crocidurine shrew dentition

Figure 8. Result of the phylogenetic analysis. A, most parsimonious tree optimized by DELTRAN approach and derived from the weighted 46 characters represented in the data matrix (Supporting Information, Supplementary Material S8: Table 1) highlighting the key character 'A3 (root): second root development' [character 20; retention index (RI) = 0.44]. Tree length = 166; consistency index (CI) = 0.37; RI = 0.50; rescaled consistency index (RC) = 0.18; homoplasy index (HI) = 0.63. B, single-rooted A3, three-dimensional model of Shargainosorex angustirostris Zazhigin & Voyta, 2018 (GIN 959/1069; Mongolian middle Miocene; Crocidosoricinae), transparent medial view. C, single-rooted A3, three-dimensional model of Sorex minutissimus (ZIN 98582), transparent medial view. D, single-rooted A3, three-dimensional model of Crocidura lasiura [ZIN 79019; character (ch.) 20: state (st.) 0], transparent medial view. E, double-rooted A3, three-dimensional model of Crocidura zaitsevi (ZIN 96320; ch. 20: st. 1), transparent medial view. F, double-rooted A3, three-dimensional model of Crocidura phanluongi (ZIN 100307; ch. 20: st. 2), transparent medial view. G, double-rooted A3, three-dimensional model of Crocidura yaldeni (ZMMU S-165343; ch. 20: st. 2), transparent medial view. Abbreviations: 1–2 in yellow circles, the nodes supported by six synapomorphies (synapomorphies 1–3, 39, 43 and 46 indicated by red arrows and filled circles; for character descriptions see Supporting Information, Supplementary Material S8); numbers above the lines are character numbers; numbers below the lines are character-state transformations; blue arrows show supposed 20th character transformation according to the parsimonious analysis: from the plesiomorphic state (0) to the apomorphic states (1 and 2).
