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.
The theory of evolution by natural selection, first formulated in Darwin's book On the Origin of Species in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
