单词	Aves
释义	Aves /ˈeɪviːz / /ˈɑːveɪz/ plural noun Zoology A class of vertebrates which comprises the birds.Let's investigate the origin and evolution of flight in our representative taxa: the Pterosauria, Aves, and Chiroptera (bats).... Hence, the possession of feathers is unique to birds and defines all members of the class Aves. Now that is fine, but if you want a pretty strong line of evidence to show that birds came from theropods, then add a lot of theropods to the class Aves. Origin Latin, plural of avis 'bird'.
