1·The question is not regarding the validity of speciation.

这个问题与物种形成论的正确性无关。

2·This is closer to biology, especially with speciation, how two distinct species form from one.

它更接近生物，尤其是物种的形成，也就是一个物种如何形成两个截然不同的物种。

3·This division set the stage for allopatric speciation among populations of fishes and other marine species.

这种划分为鱼类和其他海洋物种的分区物种形成奠定了基础。

4·Since at least Darwin time, biologists have been trying to understand and define the mechanisms for speciation.

至少从达尔文时代开始，生物学家就一直在试图理解和定义物种形成的机制。

5·Charles Darwin, the first to describe the role of natural selection in speciation, wrote about the mechanisms of speciation.

查尔斯·达尔文是第一个描述自然选择在物种形成中的作用的人，他描写了物种形成的机制。

6·Allopatric speciation can also be brought by the imperceptibly slow but colossal movements of the tectonic plates that make up Earth's surface.

构成地球表面的那些构造板块极其缓慢但剧烈的运动，也可能导致异地物种形成。

7·Given the extraordinary diversity of life on the planet, there must be mechanisms for speciation: the formation of two species from one original species.

考虑到地球上的生命的非凡多样性，一定存在着形成物种的机制：从一个原始物种演变为两个物种。

8·Some researchers have argued that speciation rates, both terrestrial and marine, could be much higher in the tropics, making them a cradle of biodiversity.

一些专家认为，在热带地区的陆地和海域，物种形成的机率更高，这样就使热带地区成为了生物多样性的摇篮。

9·Reinforcement is required for both parapatric and sympatric speciation.

对于领域性的和同域性的物种形成，强化是必需的。

10·Speciation of Zn, Mn, Fe, Ca, Mg in Ligusticum wallichii Franch was analyzed by atomic absorptionspectrometry.

利用原子吸收分光光度法对中药川芎中锌、锰、铁、钙、镁五种元素的形态进行了研究。

3·That does not rule out a gradual drift to infertility as an additional explanation, but makes it possible that infertility is a consequence, rather than a cause of speciation.

这并没有排除向不孕缓慢转变的这种补充解释，但可能的是，不孕是物种形成的结果，而非原因。

4·Researchers say the phenomenon provides evidence that differences in sensory perception — not just geography — can spark speciation.

研究人员说，这种现象提供证据证明在感官的感觉上的差异——不仅仅是地理位置——可能导致物种形成。

5·Then, sometime between 1.3 million and 2 million years ago, carnation speciation exploded.

然后，大约是在1300,000年至2000,000年前，石竹科物种形成爆发了。
