Question

Quizplus · Accepted Answer

Speciation can indeed involve changes to a single gene, which can have significant effects on the reproductive capabilities or survival of organisms, leading to the emergence of new species. This process does not always require vast expanses of time, geographic isolation, or only the accumulation of small genetic changes, as other mechanisms can also drive speciation.
