Also, the door mouse has become endangered because of destruction of woodland habitat. The Giraffe and the Okapi The giraffe and the Okapi are both examples of Adaptive Radiation. They both have a common ancestor but both have very different sized necks. A mutation has cause some of the offspring of their common ancestor to either have a very long neck, which is ideal for reaching food in tall trees, or a very small neck to reach small shrubs near the ground.
