自然选择说是由达尔文提出的关于生物进化机理的一种学说。达尔文认为,在变化着的生活条件下,生物几乎都表现出个体差异,并有过度繁殖的倾向;在生存斗争过程中,具有有利变异的个体能生存下来并繁殖后代,具有不利变异的个体则逐渐被淘汰。此种汰劣留良或适者生存的原理,达尔文称之为自然选择。他认为应用自然选择原理可以说明生物界的适应性、多样性和物种的起源。

达尔文的自然选择学说 Darwinian Natural Selection
这个人就是查理斯•罗伯特•达尔文,这本书叫做《物种起源》,而发起的挑战则是基于自然选择说的进化论。
The book was “On the Origin of Species”. And the challenge was the theory of evolution by natural selection.
“这似乎是自然选择在一个群体中发挥作用的完美机会。”伊拉尔多博士说。
"It seemed like the perfect chance for natural selection to act on a population," said Dr. Ilardo.
这一结果使许多人相信,自然选择在人类身上已经失效,也就是说,我们已经不再进化。
This has led to a belief that natural selection no longer affects humans and, therefore, that we have stopped evolving.
An animal who has evolved a brain that says, "Take care of your offspring" will do much better from a natural selection point of view from an animal who has evolved a brain that says, "Eat your offspring."
逐步形成大脑的动物说,照顾你的后代“,好过从自然选择观点,看问题的动物说,吃掉你的后代“
