一个物种的两个或更多的居群形成新物种的演化过程

AI overview

Speciation is the evolutionary process where populations gradually change over time until they become distinct species—a concept that Charles Darwin first explained through natural selection in his 1859 book *On the Origin of Species*. Understanding speciation matters because it explains how Earth's enormous diversity of life forms originated and continues to develop, helping us comprehend the relationships between all living organisms.

物種形成,又稱為種化或成种,是演化的一個過程,指生物的物種一分為二的過程。 达尔文在《物种起源》中认为自然选择是物种形成的主导因素,但一直以来认为是物种形成是随机的。直到生殖隔离的概念提出后, 自然选择在物种形成中的作用才重新受到重视。
