07年新托福阅读机经 1月13日 第一篇：进化论/自然选择 |1. |生物学的文章，关于进化的一些最新发现。首先说达尔文提出由于物种进化需要很长的时间，因此不可能会被人类观察到。但是最近的一| | |些发现却说明某些物种进化时间很短，可以被科学家所观察。然后，提出了一个关于环境与物种生存周期的假说，还说某个科学家研究一| | |种鱼类证明了这个假说的合理性。这种鱼在高处和低处都有，在低处的鱼捕食者较多，生存环境较为恶劣。科学家把低处的鱼放到高处，| | |大概十几年后，这些鱼体型变大了，生长周期变慢了，产的卵更大了，等等。然后说了另一个科学家的研究。这个科学家研究鸟类，其中| | |一种鸟的喙比另一种的大。某年，这些鸟类生存的地区气候变迁，某种坚果的产量下降；喙小的鸟只能吃较小的坚果，而喙大的鸟既能吃| | |小的坚果，也能吃大的更硬的坚果；于是更多的喙大的鸟存活了下来。而且，这些存活的鸟的后代的喙都增大了4%。后来的内容记不清了| | |，文章主要就是这样了。
