GWD27里面一个逻辑

Q22:

Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago.Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water.Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans, these species must have had to return frequently to freshwater rivers to drink.



Which of the following is most strongly supported by the information given?

1. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean.
   
   
2. Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water.
   
   
3. Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water.
   
   
4. The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys.
   
   
5. Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.
   
   感觉这题很怪啊。A选项是对的，但是看A选项那话不合逻辑啊：化石不会在。。。里发现，能这么说么？凭什么就说不会在。。。。发现呢？
   
   我知道我现在在二级推理，但是这A我觉得别扭。有人觉得A很正常吗？大家帮我看看我思路哪不对？
   
   谢谢
   
   

窝窝wooo

你说：鱼是6年前从淡水进化的，直到1年前鱼能喝咸水，虽然早期不能喝咸水的鱼也在咸水里游，它们肯定都回淡水河水。 我说：没错，这片水连不到的地方找不到5-6年前这种鱼，说明后面咸水里找到的这些鱼都是喝淡水的鱼。

我试着理解下，这题题干上没有提到任何鲸鱼会在大陆上生活，正确答案A中出现了化石不在大陆上被发现。作为缺乏这方面知识的同学是很难理解的。
背景，鲸鱼原始是陆生动物，或者是在陆上或者路上旁边的河里生活，慢慢进化到海里，到现在完全在海里生活。

题干中讲到，6千万年前鲸鱼只在河里，1千万年后开始生活在海里。所以中间的这一千万年是进化过程，就是慢慢从河里或者陆上进化到海里生活，那么这段时间的鲸鱼肯定是生活在海边和河边的交界的，才能保证偶尔下海游泳又回到河里喝喝淡水。在这个前提下，这段时间的鲸鱼是不可能被发现在被海洋隔开的另一边的大陆。即A。
