Which form of speciation is most rapid?

Question

Quizplus · Accepted Answer

Sympatric speciation via polyploidy involves the rapid duplication of chromosomes within a single population, leading to the formation of a new species. This can occur in a single generation, making it the most rapid form of speciation. Allopatric speciation, on the other hand, requires physical barriers to prevent gene flow between populations, which can take longer to form. Sympatric speciation via disruptive selection and character displacement can also occur relatively quickly, but they require specialized ecological conditions and may not always result in the formation of new species.
