This means that due to some reason if any species acquired some new traits, those traits will inherit by the next generations also. In this way, a completely new species developed. This theory of Lamarck has some supportive examples.

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.Darwin’s work in particular focused on animals of the Galapagos islands, especially finches.

Darwin’s theory of evolution by natural selection represents a giant leap in human understanding. It explains and unifies all of biology. Darwin’s theory actually contains two major ideas: One idea is that evolution occurs. In other words, organisms change over time.
