If two populations of a species develop different colours in different environments, what process may this begin?

Answer and explanation

Correct answer: Selection on variation and later speciation

Different environments can impose different selection pressures. If colour variation is heritable, one colour may improve camouflage or survival in one environment, while another colour is favoured elsewhere. Over many generations, the populations may become increasingly different. If geographical or reproductive isolation prevents gene flow for a long time, these differences can contribute to speciation. Thus option A is correct. Digestion, chromosome destruction, and becoming identical do not explain population divergence.
