Answer :
The main idea of Darwin's theory of evolution are that Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor.
All species of organisms arise and develop through the natural selection of minute, inherited variations that improve the individual's capacity for competition, survival, and reproduction, according to the Darwinism theory of biological evolution, which was developed by the English naturalist Charles Darwin (1809–1882).
Also known as Darwinian theory, it initially encompassed ideas that predates Darwin's theories, as well as the broad ideas of species transmutation or evolution that came to be accepted by the scientific community when Darwin published On the Origin of Species in 1859. The word "Darwinism" was first used in April 1860 by English scientist Thomas Henry Huxley.
