This document provides evidence for evolution by natural selection from multiple sources, including the fossil record, anatomical record, and molecular record. It discusses several key lines of evidence: - The fossil record shows changes in organisms over millions of years, with transitional fossils showing links between species. - Comparative anatomy reveals homologous structures across species that indicate common ancestry, as well as vestigial structures providing evidence of evolutionary change over time. - Molecular data, such as comparing DNA and protein sequences, provides further support for evolutionary relationships between organisms reflected in their genetic similarities.
