Evolutionary rate shifts in morphological feature of Laurasiatheria inner ears: (A) log relative basilar membrane length and (B) log number of cochlear turns. Posterior rates of morphological change in log relative basilar membrane length and log number of turns are indicated by branch colour [decrease in rate (blue) or increase in rate (red), in relation to the background rate (grey)], with the posterior probability of a rate shift occurring at a particular node indicated by the size of the filled circle (see legend for values). Clades are coloured as follows: Carnivora (red); Cetartiodactyla (grey); Perissodactyla (purple); Yangochiroptera (green); echolocating Yinpterochiroptera (blue); Old World fruit bats (orange). Clades of interest that show rate shifts are labelled as follows: (a) Yangochiroptera; (b) Molossus spp.; (c) sub-clade of Rhinolophus species; (d) Rhinolophus philippinensis morphs; (e) sub-clade of baleen whales; (f) Cetartiodactyla; (g) Sturnira spp.; (h) Pteropus spp.
