what makes the mandible unique
But the tooth-bearing mandible (jawbone) in humans is smaller in relation to the skull and V-shaped, while that of an ape is U-shaped. Another skeletal feature, the human pelvis, is more bowl-shaped than that of an ape, providing support for the abdominal organs as a result of the constant upright position of humans.he use of fire and burying the dead are also cited as evidence of what makes us human.. It certainly could be argued that using fire and evidence of burials are unique to humans, but these activities result from the spiritual nature within humans.
