When archaeopteryx , a feathered skeleton that was seemingly half dinosaur and half bird , turned up in 1862 ? three years after the publication of “ the origin of species ” ? the origin of birds became a subject of raging debate among palaeontologists 1862年是《物種的起源》出版的前三年，當時一幅始祖鳥的有翼骨骼（看起來一半是恐龍，另一半是鳥）被發現，那時鳥的起源就成了古生物學家們激烈辯論的一個主題。 |

To support his hypothesis he pointed out that several fossils of the oldest known bird , archaeopteryx , lack feathers 為了證明這種觀點，他指出，已知的最早的鳥類始祖鳥的一些化石也沒有羽毛。 |

Paleontologists also debated whether archaeopteryx could fly . 古生物學家還討論了始祖鳥是否會飛的問題。 |
