Evolution

Evolution is the process by which populations of living organisms change over successive generations. It explains the diversity of life on Earth.

Natural selection

Proposed by Charles Darwin, natural selection is the main mechanism: individuals with traits better suited to their environment tend to survive and reproduce, passing those traits on.

Evidence

Evolution is supported by fossils, comparative anatomy, and modern genetics, which shows how DNA changes over time.

Significance

Evolution is a unifying theory of biology, explaining how species arise and adapt.
