Quadrupedalism or knuckle-walking, is where primates have “very strong arms are used to support the upper body weight while positioned on the backs of the finger’s middle phalanges.” For bipedalism, “it’s one of the key features of the human lineage, freeing the hands for carrying and for using and making tools” (Thorpe). The thing that is unique about these two is where the foramen magnum is located at. For apes, monkeys, and similar animals, the magnum is toward the back of the skull, whereas the humans have it on the bottom of the skull. In the end, primates are different by humans by walking with their arms and legs instead by using just the legs like how humans
