The universe is a system made up of the stars, planets and the space surrounding them. The earth is the one of the planets in the universe. Plants, animals and other organisms like man, inhabit the earth. For many centuries man has witnessed and appreciated changes, which occur in nature and within his immediate surroundings. For example many thousands of years ago the Sahara desert was not there, instead the entire area was covered with a thick forest. Due to changes in weather the forest gradually disappeared and gave way to present desert. All this gives us the concept about organic evolution.
