鳥類是由何種物種演化而來,曾經存在非常大的爭議,因為一直未能找到相關的演化證據。不過隨著介於恐龍和鳥類之間的中間型物種化石證據陸續出爐,像是始祖鳥、近鳥龍、中華龍鳥、尾羽龍等,終於讓爭議不休的鳥類起源之謎逐漸清晰,現在科學家對鳥類所持的觀點是:「鳥類是指一群有羽毛,並演化出飛翔能力的獸足類恐龍。」
Summary
[edit]Description雙角犀鳥標本.jpg |
中文(繁體):雙角犀鳥(Buceros bicornis)標本,臺北市士林區街上次分區福佳里(福德洋庄洲尾頭)
English: There was once much controversy surrounding the evolution of birds, as relevant evudence was lacking. However, as fossil evidence of intermediary species between dinosaurs and birds, such as Archaeopteryx, Anchiornis, Sinosauropteryx, and Caudipteryx, continues to emerge, the origin of birds is gradually becoming less of a mystery. Now, sccientists hold the view that, "Birds are a group of theropod dinosaurs that possess feathers and evolved the ability to fly." |
