Much of the phenotypic diversity in the wild is hypothesized to be caused by natural selection. Selection is unique among mechanisms of evolution because it can cause adaptation, the evolution of traits that enhance reproduction and survival. Athough Darwin proposed selection as a mechanism of evolution over 100 yr ago, only in the last 30 yr have biologists documented the process of adaptive evolution in present-day populations of species such as Darwin's finches.

大部分野生动物的表型多样性被假设是由自然选择引起的。选择在进化机制中是独一无二的，因为它可以引起适应，即增强繁殖和生存的性状的进化。尽管达尔文在100多年前就提出了选择是进化的一种机制，但直到最近30年，生物学家才记录了现代物种种群（如达尔文雀）的适应性进化过程。
