翻译：对于一些来自巴基斯坦的，四千七百五十万年的化石的研究，让我们对现代鲸的祖先有了一些新的理解。比如说，M. i 是一种适应了海洋生活的陆生动物。一块 M. i 化石怀着胎儿，其位置显示分娩时胎儿先出头，这是陆生哺乳动物的典型特征且意味着这个物种在岸上生产。但它大概多数时候呆在水中：它的大牙齿适合捕鱼，同时它的鳍状足肯定不方便行走。

不难，时间充裕的话应该做对。

Maiacetus inuus 慈母鲸，完全不需要认识

encase 把…装入…(～ A in B)，一般用被动语态，本句没用。

incompatible 不相容的，矛盾的，相克的

鳍状足能不能走路?能，海狮，海象，海豹，都能短距离地半爬半拱地走几步，但确实能。所以你只能说它笨拙 clumsy，鱼上岸才叫 incompatible with walking 。

最后说一说 while，它在本题中，只适合理解为 and / similarly and at the same time that，如果你按以前 while 引导对比或让步关系的套路去理解，很可能就被误导了。
