Answer: 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.Charles Darwin’s theory of evolution had three main components: that variation occurred randomly among members of a species; that an individual’s traits could be inherited by its progeny; and that the struggle for existence would allow only those with favorable traits to survive.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.In this article, we'll examine the evidence for evolution on both macro and micro scales.
