Editor's Notes
EXAMINE THE PICTURE?
WHAT DOES IT REPRESENT?
HOW DOES IT EXPLAIN MAN’S DEVELOPMENT?
It is a common understanding that change is the only permanent thing in this world.
Everything is a dynamic and as such undergoes transformation.
Likewise man as the most important component of society goes through evolutionary changes that help him adapt the environment.
Scientists became interested in studying the origin and evolution of man especially in analyzing mans capacity to cope with the environment
