Chapter 10, Problem 4ER

Summary Introduction

To discuss: The significant anatomical differences between some of initial hominines and particular australopithecines and contrast the cranial and dental morphology of gracile and robust australopithecines.

Introduction:

The earliest hominines comes into existence during the changeover from an arboreal lifestyle to terrestrial lifestyle, due to this the fossils of these initial hominine species have selected anatomical features which reflect bipedality and few traits resembles arboreality. Over the time period of million years the traits of arboreal such as grasping foot vanished from fossil records.

Significant anatomical changes takes place in hominines consist the outstanding increase in robust city and size of the chewing machine. These changes vanish with extinction of frenzied robust australopithecines.
