Summary Introduction

To discuss: The role of climate fluctuations played in the appearance and evolution of first hominines

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.
