Choanate vertebrates’ acoustic communication ancestral state reconstruction analysis: tree includes 1,800 choanatian species assigned either with the character presence or absence of acoustic communication; pie charts at ancestral nodes indicate likelihood of each character state; colors in the spectrograms represent sound intensity, with warm colors representing high intensity and cold colors (i.e. blue) representing low intensity or absence of sounds.
