Detailed explanation-1: -Therefore, he called this type of selection natural selection. Darwin knew artificial selection could change domestic species over time. He inferred that natural selection could also change species over time. In fact, he thought that if a species changed enough, it might evolve into a new species.

Detailed explanation-2: -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-3: -Darwin relied on the use of analogy and inductive reasoning to support his theory of natural selection. Invoking the philosopher William Whewell’s notion of “consilience of inductions, ” Darwin argued that any theory that was able to explain so many different classes of facts was not likely to be false.

Detailed explanation-4: -Clearly, he did not invent the idea. That happened long before he was born. However, he carried out the necessary research to conclusively document that evolution has occurred and then made the idea acceptable for scientists and the general public.

Detailed explanation-5: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
