Question

Quizplus · Accepted Answer

Speciation can occur through geographic isolation, which leads to populations evolving separately and eventually becoming distinct species. This is known as allopatric speciation, and it is a common mechanism for speciation. Speciation is not directed and can occur in various types of species, not just ring species. Additionally, while speciation can lead to changes in the variation within populations, it does not necessarily reduce variation overall, as new species can continue to evolve and diversify.
