If two populations develop different colours in different environments and remain isolated for a long time, what may happen later?
Answer and explanation
Correct answer: They may become new species
The governing concept is speciation through variation, selection and reproductive isolation. Different environments can favour different colour variants, and long-term separation prevents regular interbreeding. As distinct genetic differences accumulate, the populations may become reproductively isolated and eventually form new species. This is a possibility over generations, not an immediate result. Isolation does not remove all genes or variation, so options B, C and D are incorrect.
