Detailed explanation-1: -The theory of evolution is a shortened form of the term “theory of evolution by natural selection, ” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.

Detailed explanation-2: -Darwin’s greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin’s discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science.

Detailed explanation-3: -The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Detailed explanation-4: -The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.
