The crucial break from the concept of constant typological classes or types in biology came with the theory of evolution through natural selection, which was formulated by Charles Darwin and Alfred Wallace in terms of variable populations. Darwin used the expression "descent with modification" rather than "evolution".

Evolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation.

Darwin imagined that the island species might be all species modified from one original mainland species. In 1860, he wrote, “seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.”Most travelers following in Darwin’s footsteps go to the Galápagos.

It is first presented as applying only to the divergences taking place at the varietal level, with varieties represented by the small lower-case letters within species A–L of a “wide ranging genus”, with the horizontal time coordinates measured in terms of a limited number of generations. Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features.

Evolutionary thinking is having a revolution . . .Darwin's Theory of Evolution: Darwin's theory of evolution, proposed in "On the Origin of Species," states that species evolve over time through natural selection.

Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is ...Darwin's five postulates of natural selection are: 1. More organisms are born than can survive. 2. There is variation -- some are better at survival and reproducing. 3.
