物种形成

Speciation is the process by which new species arise from a single ancestral species.
物种形成是新物种从单一祖先物种中演化产生的过程。
Allopatric speciation occurs when populations of a species become geographically isolated, leading to genetic differences and eventually new species.
地理隔离物种形成是指一个物种的不同种群因地理隔离而产生遗传差异，最终形成新的物种。
sympatric speciation happens when new species evolve within the same geographic area without geographic isolation.
同域物种形成是指在同一地理区域内，没有经过地理隔离的情况下，新物种进化形成。
The evolution of flight in birds is an example of how adaptive radiation can lead to rapid speciation events.
鸟类飞行能力的进化就是一个例子，说明了适应性辐射如何导致快速的物种形成事件。
Hybridization between closely related species can sometimes result in speciation if barriers to reproduction persist over time.
密切相关的物种间的杂交有时如果长期存在生殖隔离，则可能导致物种形成。
The discovery of distinct species in a previously unstudied region highlights the ongoing process of speciation in nature.
在以前未被研究的地区发现不同的物种突显了自然界中持续进行的物种形成过程。
Sexual selection can contribute to speciation by promoting the development of traits that prevent interbreeding between populations.
性选择可以通过促进防止不同种群间交配的特征发展来推动物种形成。
Speciation through polyploidization involves the doubling or multiplication of chromosomes, creating genetically distinct lineages capable of reproductive isolation.
多倍体化途径的物种形成涉及染色体加倍或成倍增多，创造出能够实现生殖隔离的遗传上独特的谱系。
The formation of new cichlid fish species in Lake Victoria is a classic case study of rapid sympatric speciation driven by ecological niche partitioning.
维多利亚湖中新慈鲷鱼种的形成是一个经典的由生态位分化驱动的同域快速物种形成的案例研究。
Climate change can facilitate speciation by pushing organisms into new habitats with different selective pressures, leading to divergence in adaptation.
气候变化可以通过将生物推入具有不同选择压力的新栖息地，进而导致适应性的分化，从而促进物种形成。
