Chapter 22.3, Problem 3C
Summary Introduction
To explain: The way in which australopithecines and Homo differ.
Concept introduction: Hominins are the group of all extinct human-like species and humans, where they show the unique characteristic of bipedalism. Human beings (Homo sapiens), Homo genus, and australopithecines are included under the Tribe Hominini. They are the most advanced placental mammals with a large cerebrum and cerebellum.
