What is the theory of evolution? Quick Answer. The theory of evolution proposed by Charles Darwin entails the evolution by natural selection of all life on earth. It states that new generations are born with different inheritable traits, and that the traits that are superior for survival will be passed on to new generations.
Natural selection and adaptation are two basic concepts which are coming under Darwinâs Theory of Evolution. In Darwinâs theory, he said that all life is related and has descendants from a common ancestor. All species, therefore, can include in a vast tree of life. Natural selection is the known cause of adaptations, but the other non-adaptive causes like mutation and genetic drift are also responsible for evolution of life on earth.
