自然选择

He stumbled upon a volume, The Genetical Theory of Natural Selection, written by R.

费希尔（6在1929年写的《自然选择的遗传理论The Genetical Theory of Natural Selection》，顿时受到启发。

For example, the genetic model which was found by Gregor Mendel, endowing the theory of nature selection with a genetic mechanism; The discovery of DNA gives a mechanism to genetics and we can see a evolutionary pedigree consequently; Developmental biologhy also gives a mechanism, but to the DNA; Besides, evolution has played a role in research on medicine as well as disease, etc.

孟德尔的遗传模式赋予了达尔文自然选择理论一个遗传学机制；DNA的发现赋予了遗传学一个机制，让我们能看到进化的世谱；发生生物学又赋予了DNA一个机制；此外还有进化在医学和疾病中扮演的角色研究等等。

Haldane established that natural selection could work in the real world at a faster rate than even Fisher had assumed.

霍尔丹使人们接受这样一个概念，自然选择可以在现实世界中以比费希尔假定更快的速度起作用。

Haldane applied mathematical analysis to real world examples of natural selection such as the evolution of industrial melanism in peppered moths.

霍尔丹发表了一系列的论文，将数学分析应用到真实世界的自然选择例子，如椒粉蛾工业黑变病的进化。

If the variations that affect reproduction are heritable , the outcome is evolution by natural selection.

如果影响繁衍的变异是可遗传的，自然选择的结果就是进化。

What natural selection does is change the relative frequencies of alternative phenotypes, insofar as they are heritable.

自然选择的作用是在可遗传的表型范围内，改变可供选择的替代表型的相对频率。

Natural selection was expected to work very slowly in forming new species, but given the effectiveness of artificial selection, he could "see no limit to the amount of change, to the beauty and infinite complexity of the coadaptations between all organic beings, one with another and with their physical conditions of life, which may be effected in the long course of time by nature's power of selection".

预计在形成新物种上，自然选择起效非常缓慢；但考虑到人工选择的有效性，他可以"设想到变化的数量是无限的，美丽是没有限度的；所有有机生命之间的互相适应的复杂性是无限的，彼此之间的相互适应以及它们生活状况之间的相互适应是无限复杂的，这些都可能在很长的时间里受到自然力量选择的影响"。

Varieties that did not replicate or did so inaccurately...

末句总结自然选择的结果是提高了复制分子的效率

In 1865 he succeeded his father as director of Kew Gardens, which became an international center for botanical research.

虎克作为众多达尔文学术观点的支持者之一，其研究结果对于促进达尔文和华莱士共同提出关于通过自然选择的进化理论起到了一定帮助。1865年虎克继承父业，任丘园植物园园长，此后该园成为国际植物学研究中心。

The body of these changes is through a long-term natural selection, so that useful genetic variation retained by the formation, and no explanation is based on Lamarckism, to use and disuse of the way, from generation to generation improved the sake of time.

机体的这些改变是通过长期的自然选择，使有益的变异通过遗传保留下来而形成的，绝不是按拉马克主义的解释，以用进废退的方式，一代代完善化而形成的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
