Which of the following contributes to speciation by dividing continuous populations? A) Geographic isolation B) Artificial selection C) Ecosystem changes D) Genetic mutation

Understand the Problem

The question is asking which factor contributes to the process of speciation by dividing populations that are continuously distributed. This involves understanding concepts related to evolutionary biology and how different factors can isolate populations leading to the development of new species.

More Information

Geographic isolation is a major driver of speciation, especially in allopatric speciation. When geographical barriers split a population, it can lead to the development of distinct species over time due to the lack of gene flow and separate evolutionary paths.

Tips

A common mistake is confusing geographic isolation with other influences like genetic mutation or ecosystem changes. Only geographic isolation physically separates populations.
