biological evolution,convergence,parallel evolution By a process of elimination, therefore, the three researchers were left with the conclusion that, by pushing metabolic rates up, tropical heat causes more mutation and thus more speciation.
因此，三位研究人员得到如下结论：由于代谢速度的提升，热带地区的热量引起更多的突变，也因此形成更多的物种。 ecocn
The niche model of speciation thus looks proved.
物种形成的环境模型被证明是正确的。 ecocn
The two main schools of thought about speciation that emerged in the20th century to fill this intellectual vacuum can be summed up as“ breeding defined” and“niche defined”.
20世纪出现的填补了这项学术空白的两大思想学派可被总结为“繁殖决定型”和“环境决定型”。 ecocn
As the relative young geology age, the time of speciation was shorter and the differentiation later in Taizi Mountains. So the flora elements were younger.
由于本地区地质年代相对年轻，物种形成时间较短，分化较晚，所以区系成分比较年轻。 cnki
But the fossil record of placental mammals is reliable and does not record a speciation until later.
但是胎盘类哺乳动物的化石记录是可靠的，却没有在那之前记录下物种进化的现象。 yeeyan
Indeed, many think that regulatory changes are at the heart of speciation and may have played a large role in the evolution of humans from their predecessors.

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。 yeeyan
Researchers usually link speciation to some sort of physical barrier, such as a river or mountain, which divides populations and causes them to evolve independently.
研究人员通常把物种形成与某种物理屏障相联系，如河流或山脉，这种屏障分隔种群，使它们独立进化。 yeeyan
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。 yeeyan
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。 ecocn
