Evolution helps explain the diversity of life on Earth and how species have adapted to their environments over time through processes such as natural selection and genetic drift.
Evidence for evolution comes from a variety of sources, including the fossil record, comparative anatomy, molecular biology, and biogeography.

Molecular biology has allowed scientists to study the genetic similarities and differences between organisms, providing further evidence for evolutionary relationships.
