Fig. 1: Choanate vertebrates’ acoustic communication ancestral state reconstruction analysis.
From: Common evolutionary origin of acoustic communication in choanate vertebrates
Tree includes 1800 choanatian species assigned either with the character presence or absence of acoustic communication. Pie charts at ancestral nodes indicate likelihood of each character state. Colours in the spectrograms represent sound intensity, with warm colours representing high intensity and cold colours (i.e. blue) representing low intensity or absence of sounds. Character states for each species can be accessed in Supplementary Data 4.
