Fig. 3.

Simplified ancestral state reconstructions, showing potential transitions between character states. The same phylogeny as in Fig. 2A–C is shown, with the outgroups positioned at twelve o' clock and subsequent clades arranged in a clockwise manner. Characters were traced over 2 000 bootstrap trees and those that were recovered in the majority are coloured on the nodes. In the case of equivocal construction no colour was used (white). To simplify the figure, only clades with two or more neighbouring character states are shown.
