Though Darwin proposed natural selection as the primary evolutionary mechanism, he accepted other auxiliary mechanisms too. The most important of these was the transmission of acquired characteristics (those acquired by use-disuse) first proposed by Lamarck in the early 1800s..
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.
