进化生物学家经常认为生态学在物种形成中很重要，因为自然选择可能会驱动居住在不同环境中的谱系之间的适应性分歧。我认为，这是倾向的血统，以保持其祖先的生态位（系统发育生态位保守主义）和他们的失败，以适应新的环境，经常孤立的初期物种，并开始了形成的过程。生态位保守性可能是异域物种形成的一个重要而广泛的组成部分，但在很大程度上是未经研究的。这里概述的观点表明了关键微进化过程的作用（即，自然选择，适应），这与以前的生态学和物种形成文献中提出的那些截然不同。然而，这种观点是对传统观点的补充，因为它侧重于物种形成过程的不同时间阶段。
Evolutionary biologists have often suggested that ecology is important in speciation, in that natural selection may drive adaptive divergence between lineages that inhabit different environments. I suggest that it is the tendency of lineages to maintain their ancestral ecological niche (phylogenetic niche conservatism) and their failure to adapt to new environments which frequently isolates incipient species and begins the process of speciation. Niche conservatism may be an important and widespread component of allopatric speciation but is largely unstudied. The perspective outlined here suggests roles for key microevolutionary processes (i.e., natural selection, adaptation) that are strikingly different from those proposed in previous literature on ecology and speciation. Yet, this perspective is complementary to the traditional view because it focuses on a different temporal stage of the speciation process.
