Summary Introduction
To explain: Factors describing the evolution of the jaws as well as robust faces of Australopithecus, specifically in the early Pleistocene.
Introduction: The pre-australopithecines were found to be the earliest hominins according to the fossil record and they lived around 7 to 4 million years ago. They were followed by australopithecines, who lived before 4 to 1 million years ago.
