Sympatric speciation is more accepted by scientists than allopatric speciation.

Question

Quizplus · Accepted Answer

Allopatric speciation, which occurs when a population is geographically separated and evolves independently, is generally more accepted by scientists than sympatric speciation, which occurs when populations diverge while inhabiting the same geographic region. This is because sympatric speciation requires mechanisms for reproductive isolation to evolve within a shared environment, which is considered more complex and less likely to occur than geographic isolation in allopatric speciation. However, there is still ongoing research and debate about the relative importance of these two modes of speciation in different taxa and circumstances.
