I reproduce below the portion being taught to all students of Std VI in Maharashtra:
Evolution of Man: The earth is a planet in the solar system. The earth came into being about 4500 million years ago. At first, it was in the gaseous state. Gradually, over a period, it solidified and land formed. Water bodies developed on land. Algae-like plants developed in water. At about this time, unicellular micro-organisms were formed. Animals on earth evolved in stages from these unicellular micro-organisms. The process of development of the living world from unicellular living beings to manis known as evolution. This evolution has taken place over millions of years.
Today's man evolved in stages from ape,a monkey closely resembling man. The two main stages in this evolution are H_omo Erectus and H_omo Sapiens. The word H_omo indicates man and Er_ectus indicates with upright spine. H_omo sap_iens means the wise man. At this stage, he began to make fire and devise stone implements.
