Fig. 22. Optimization of the absence [0] and presence [1] of M2 in the optimal tree from the combined analysis of Giannini and Simmons (2005; modified from their fig. 7). Dotted branches connect nodes with ambiguous final assignments [0/1]. Some internal node assignments are omitted for clarity.
Fig. 20 in Element Homology and the Evolution of Dental Formulae in Megachiropteran Bats (Mammalia: Chiroptera: Pteropodidae)
Fig. 20. Optimization of the absence [0] and presence [1] of upper incisors in megabats, using the optimal tree from the combined analysis of Giannini and Simmons (2005; modified from their fig. 7). Optimization of the absence/presence of I1 absence/presence is represented along the branches. Optimization of the absence/presence of I2 is shown with black arrows representing a 1 + 0 transformation (loss of I2). Absence/ presence of both I1 and I2 is inapplicable in the outgroup Megaderma lyra as this bat lacks the premaxillary bone that supports the upper incisors when present.
