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.
Detailed explanation-2: -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.
Detailed explanation-3: -In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce.
Detailed explanation-4: -In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.
