Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.

Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.
