The term Darwinism had been coined by Thomas Henry Huxley in his April 1860 review of  On the Origin of Species , and by the 1870s it was used to describe a range of concepts of evolutionism or development, without any specific commitment to Charles Darwin 's own theory.
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.
