When dark-colored mice from two different populations living hundreds of miles apart were examined, the mice looked nearly identical. Their dark color was caused by two different genes. What does this tell you? (Note: More all correct answer) Group of answer choices A. Dark fur color evolved independently on each lava flow. B. there are at least two genes involved in creating dark-colored mouse fur. C. Dark-colored fur evolved only once in rock pocket mice. D. Under similar conditions, natural selection can favor similar adaptations. E. Different mutations in two different genes cannot generate the same phenotype.

Evolutionary adaptations

Evolutionary adaptation is the process through which organisms adapt or adjust to their surroundings to increase the chances of survival, mating, and reproduction. An organism's behavior, physiology, and structure are adjusted or changed to make it more suited to its environment.
