2009-08-15的鲨鱼危机最后一句话
But the larger sharks, the carnivore sharks that bite hooks very easily, some of the oceanic sharks that are easily picked up by long liners and so forth, those are the ones that seem to be most in danger. Not necessarily endangered, some of them are, but in danger.
其中三个听上去差不多的in danger，在这句话里应该怎么理解啊？

wind-borne

这样说，endangered 的程度要比 in danger 严重得多
刚刚查到endangered=one that soon may no longer exist
这就有点明白了

请问SSS 20090824 的最后一句话

Ironically, it’s natural selection that keeps the human appendix from shrinking away completely, because smaller ones are more likely to become infected, and keep your genes out of the pool.

人类的阑尾没有完全萎缩是自然的选择，因为较小的脏器不易受感染。最后半句out of the pool是什么意思？

wind-borne

啊哦，上半句就理解错了，应该是较小的脏器易受感染，所以基因不能遗传
明白了，谢谢！
