Summary Introduction
Introduction: The primates are the only group of mammals that can extensively use their forelimbs for the purposes other than locomotion. Hominins are primates that include humans and their extinct ancestors. Hominins are the group of all extinct human-like species and humans, where they showed the unique characteristic of bipedalism. Human beings and their ancestors are included under the tribe: Hominini. They are the most advanced placental mammals with large cerebrum and cerebellum.
