Introduction:
Evolutionary biology is the study of history of life forms on earth.To understand the changes in flora and fauna that have occurred over millions of years on earth , we must have an understanding of the context of origin of life , of stars, of earth and indeed universe itself.This is the story of origin of life and evolution of life forms or biodiversity on planet earth in the context of evolution of earth and against the background of evolution of Universe itself. Evolution is revealing of hidden potential ties that bring about an orderly change from one condition to another.Cosmic evolution deals with the sequence of changes that occur in inorganic matter and its evolution. Darwinism or theory of natural selection is a theory of organic evolution which states that newly species evolve over a long period of time through accumulation of small variation which provides organisms overs structural and functional superiority over others In their survival and differential reproduction.
Charles darvin went around world is a naturalist in HMS Beagle . Darvin was influenced by two books principle of geology by Charles lyel and an essay on population by TR Malthus. He gave the idea about limited resources, high reproductive pressure, struggle for existence and natural selection. Darwin proposed origin of species through evolution.
