A hypothesized evolutionary history of echolocation among bat families. Oral emission has been supported as the ancestral state by previous molecular and fossil studies [40, 41], but there remains uncertainty on this character state. Skull images show representatives of each echolocation type: from the top—Pteropus poliocephalus, Hipposideros caffer, and Mormoops blainvillei. Yin = Yinpterochiroptera, Yan = Yangochiroptera
