Question

Quizplus · Accepted Answer

Allopatric speciation, which occurs when populations are geographically isolated and evolve independently, is the dominant mode of speciation in most groups of mobile animals. This is because mobile animals are more likely to disperse and become geographically isolated, leading to the evolution of reproductive isolation and eventually speciation. Sympatric and polyploid speciation are more common in plants. The statement "not reliant on reproductive isolation" is incorrect, as reproductive isolation is a necessary component of speciation.
