Question

Quizplus · Accepted Answer

Allopatric speciation typically involves geographic separation, making statement I incorrect. It is indeed the most common form of speciation, as geographic isolation is a common way for populations to become genetically distinct, supporting statement II. Genetic drift, along with natural selection, can drive the genetic divergence necessary for speciation in geographically isolated populations, making statement III correct.
