The correct answer is darker skin. Chimpanzees have light skin under all their fur. The common ancestor we share with chimpanzees probably had lighter skin, like other primates. Genetic evidence shows that dark skin evolved in the human lineage about 1.2 million years ago, as our ancestors became less hairy. Mimicry is an evolved resemblance between an organism (the mimic) and another entity (the model), which can be a nonliving object or an unrelated species.
