The Origins Of Cetaceans 鯨類動物起源 譯文
The Origins Of Cetaceans 鯨類動物起源 譯文
眾所周知,鯨類動物是哺乳動物,如鯨魚、鼠海豚和海豚。他們用肺呼吸,而不是腮,屬於胎生。鯨類動物成流線形的身體,後腿的消失,尾片和氣孔的出現,這些特徵都不能掩飾它們和陸生哺乳動物的相似之處。然而,想知道世上第一隻鯨長什麼樣並非易事,不像還原海獺及鰭足類動物(四肢水陸兩用如海豹、海獅、海象)的原貌那麼簡單。一些完全水生的鯨類動物雖然已經滅絕,但仍可通過化石來對它們進行考察。陸棲哺乳動物和海洋鯨類之間有何聯繫? 近期發現的化石已經可以很清晰地幫助人們了解這個問題,以及他們之間的過渡關係。
