How does the modern synthetic theory of evolution work?

The modern synthetic theory includes scientific evidence from genetics. It explains the concepts which occur when the allele frequency of the population changes. According to this theory, when the changes are great enough, there is a formation of new species.

Why is natural selection important to the theory of evolution?

Natural selection was such a powerful idea in explaining the evolution of life that it became established as a scientific theory. Biologists have since observed numerous examples of natural selection influencing evolution. Today, it is known to be just one of several mechanisms by which life evolves.
