How does coevolution lead to speciation?

Question

Quizplus · Accepted Answer

Coevolution occurs when two species influence each other's evolution. An adaptation in one organism can drive adaptation in a second organism, creating a so-called "arms race" where both species continue to evolve in response to each other. This can lead to the development of traits that make each species better suited to interacting with each other, which can ultimately result in reproductive isolation and speciation. Thus, coevolution can lead to speciation by driving the evolution of traits that create barriers to gene flow between populations.
