Question

Quizplus · Accepted Answer

The basin-shaped pelvis is a characteristic of bipedalism, which is unique to hominins (humans and their ancestors). The central foramen magnum (the hole at the base of the skull where the spinal cord enters) shifted forward with the evolution of bipedalism. Arched feet are also a characteristic of hominins, as they aid in shock absorption during walking and running. Apes, monkeys, and prosimians all have different skeletal features that distinguish them from hominins.
