The theory of evolution is a scientific theory that explains how species of living things change over time. It is one of the fundamental keystones of modern biological theory 1. Here are some main points of the theory:
Evolution occurs through a process called natural selection, where organisms with traits that are better adapted to their environment have a higher chance of survival and reproduction.
Species change over time and can give rise to new species .
All living things share a common ancestor .
Variation exists within all populations of organisms .
Evolution occurs slowly over many generations.
