Fossils, biochemical evidence, and homologous structures all support the theory of evolution by providing physical, molecular, and anatomical evidence of common ancestry and evolutionary processes.
Fossils: Fossils provide physical evidence of past life forms and transitions, showcasing the process of evolution over time. For example, the fossil record for ancestors and relatives of the horse demonstrates evolutionary changes in response to shifting environments.
Biochemical evidence: Molecular similarities found in all species of organisms, such as DNA sequences, provide strong evidence for common ancestry and the relatedness of different species through evolution.
Homologous structures: Homologous structures, like the similar bone structures in the limbs of different mammalian species, indicate common ancestry and evolution from a shared ancestor.
