Question

Quizplus · Accepted Answer

Speciation occurs when one species splits into two or more species, typically through reproductive isolation. This can occur through various mechanisms, such as geographic isolation or changes in mating behavior. While it may occur over long periods of time, it is possible for scientists to observe the emergence of new species in certain contexts, such as with the appearance of polyploidy plant species.
