Detailed explanation-1: -Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.
Detailed explanation-2: -Darwin’s observations that led to his theory of natural selection are: Overproduction-all species will produce more offspring than will survive to adulthood. Variation-there are variations between members of the same species. Adaptation-traits that increase suitability to a species’ environment will be passed on.
Detailed explanation-3: -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-4: -The Theory of Evolution by natural selection was first formulated in Charles Darwin’s book “On the Origin of Species (opens in new tab)” published in 1859.
