Karl Gegenbaur (21 August 1826 – 14 June 1903)〔"Karl Gegenbaur - Encyclopaedia Britannica" (biography), ''Encyclopædia Britannica'', 2006, Britannica.com (Britannica-KarlG ).〕 was a German anatomist and professor who demonstrated that the field of comparative anatomy offers important evidence supporting of the theory of evolution.〔 As a professor of anatomy at the University of Jena (1855–1873) and at the University of Heidelberg (1873–1903), Karl Gegenbaur was a strong supporter of Charles Darwin's theory of organic evolution,〔 having taught and worked, beginning in 1858, with Ernst Haeckel, 8 years his junior. Gegenbaur's book ''Grundzüge der vergleichenden Anatomie''〔 Also titled ''"Grundriss der vergleichenden Anatomie"'' (1859), "Biodiversity Heritage Library", (biodivlib-Anatomy ). 〕 (1859; ''Elements of Comparative Anatomy'') became the standard textbook, at the time, of evolutionary morphology, emphasizing that structural similarities among various animals provide clues to their evolutionary history.〔 Karl Gegenbaur noted that the most reliable clue to evolutionary history is homology, the comparison of anatomical parts which have a common evolutionary origin.〔 Gegenbaur had been a student of Albert von Kölliker, Rudolf Virchow, Heinrich Müller and Franz Leydig (1821–1908).〔 "Carl Gegenbaur - Wikipedia" (German), German Wikipedia, 2006-10-29, de.wikipedia.org webpage: GermanWP-CarlGegenbaur. 〕 ==Life== Karl Gegenbaur was born in Würzburg, Bavaria in 1826, and he entered the University of Würzburg as a student in 1845. After taking his degree in 1851, he spent some time in travelling in Italy and Sicily, before returning to Wurzburg as Privatdozent in 1854. In 1855, he was appointed extraordinary professor of anatomy at the University of Jena, and in 1858, he became the ordinary professor, where after 1865, his former student and fellow-worker Ernst Haeckel was professor of zoology. In 1873, Karl Gegenbaur was appointed to Heidelberg, where he was professor of anatomy and director of the Anatomical Institute until his retirement in 1901. He died on 14 June 1903, at Heidelberg.〔 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「Karl Gegenbaur」の詳細全文を読む スポンサード リンク
