翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Alan Feduccia ： ウィキペディア英語版 Alan Feduccia John Alan Feduccia (born 25 April 1943〔(Library of Congress entry )〕) is a paleornithologist, specializing in the origins and phylogeny of birds. He is now Professor Emeritus at the University of North Carolina. Feduccia's principal authored works include two books, ''The Age of Birds''〔Feduccia (1980)〕 and ''The Origin and Evolution of Birds'',〔 and numerous papers in various ornithological and biological journals. Feduccia is best known for his criticisms of the widely held view that birds originated from and are deeply nested within Theropoda, and are therefore living theropod dinosaurs. He has argued for an alternative theory in which birds share a common stem-ancestor with theropod dinosaurs among more basal archosaurian lineages, with birds originating from small arboreal archosaurs in the Triassic. ==Education== Feduccia graduated with a B.S. from Louisiana State University, taking ornithological expeditions to Honduras, El Salvador and Peru. He received his M.A. and Ph.D. (1969) from the University of Michigan. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alan Feduccia」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
