The skeletons of humans and gorillas have many similarities but also some key differences. Both have the same basic skeletal structure, with a skull, spine, ribcage, two arms, and two legs. However, a gorilla’s skeleton has many adaptations for its lifestyle.

Gorillas have a much more robust and larger skull to support their powerful jaw muscles. Their arms are longer than their legs, the opposite of humans, to allow knuckle-walking. Gorillas also have broader shoulders and a wider ribcage for anchoring their large muscle mass. Their pelvis is wider to accommodate their large gut.

The bones of gorillas are thicker and denser to support their greater body weight. For example, the leg bones of a gorilla are much thicker than a human’s. Gorillas have thicker vertebrae in their neck to hold up their large head. Hand and foot bones are also larger with increased crests and articulations for climbing.

Overall, the gorilla skeleton is adapted for an extremely muscular, quadrupedal lifestyle. It contrasts with the more gracile, bipedal-adapted skeleton of humans. The differences reflect our distinct modes of locomotion and diets.
