Why are ring species important to our conception of the evolutionary process? A. They demonstrate the power of genetic drift in building local adaptation. B. They demonstrate the kinds of mutations that are most likely to increase fitness and therefore to spread via natural selection. C. They demonstrate that most populations of animals can interbreed. D. They demonstrate that small changes can add up to a species-level difference. .
