Explain Darwin's theory of evolution by natural selection.
Darwin's Theory of Evolution by Natural Selection are as follows:
1. The organisms with useful traits and higher adaptability will survive. The fittest organism will be able to survive in the world.
2. Naturally selected over-abundance of offsprings can lead to a struggle for existence. Organisms with variations can survive and reproduce in an effective manner, producing a large number of offsprings with a longer life span.
3. Offspring of survivors inherit the useful variations to the new generation and this variation becomes an inherited feature. Due to the environmental adaptation, the organism with variation adapt and survive in new living conditions.
