Chimpanzees and humans are very similar in many ways including skeletal muscle structure but chimpanzees are able to generate at least twice the force as humans of the same mass.
An additional difference is that humans have much greater fine motor control.
Current hypotheses describing these differences are that chimpanzees have fewer motor units for a given number of muscle fibers and human central nervous systems put a limit on the number of motor units that may be stimulated at one time.
Explain physiological differences between humans and chimpanzees using the hypotheses mentioned above.
