A response paper rejected this hypothesis based on paleontological and developmental data. Stem-bats such as Onychonycteris and Icaronycteris were already capable of flying and the latter was a laryngeal echolocator. Contrary to the hypothesis of multiple flight origins, which assumes a bat ancestor with only handwings and no plagiopatagia ...
Unlike migratory birds, which fly during the day and feed during the night, nocturnal bats have a conflict between travelling and eating.
