Natural selection is based on four main principles: variation, overproduction, adaptation and descent with modification. Briefly explain how each of these principles is necessary for natural selection to occur. Variation = natural variation in genetic code, due to mutations. Without this, change would never occur.The idea of natural selection or survival of the fittest theory by Darwin was based on a few main points: Often, traits are inheritable. Many features are inherited, or passed down from parent to progeny, in living organisms.

Variation According to Darwin, organisms do not adapt to the environment – the variation in their traits is a preexisting state, and the environment simply favors organisms with certain variants of these traits.Natural selection occurs if the following 4 criteria are met.
