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..
Darwin Theory of natural selection was proposed by Charles Darwin in 1858. Darwin believed all plants and animals had evolved from a few common ancestors by means of natural selection. Plants and animals produce many offspring, but some of the young die before they can become parents. According to Darwin's theory, natural selection determines which members of a species die prematurely and which ones survive and reproduce. All living things must compete for a limited supply of food, water, space, and other necessities.
