How are fossils and homologous organs both evidence of evolution?
Answer and explanation
Correct answer: Fossils show ancient life, and homologous organs suggest common ancestry.
Fossils are preserved remains or traces that provide a record of organisms living in the past and can show changes through geological time. Homologous organs have the same basic structural plan in different organisms, even when their functions differ, suggesting inheritance from a common ancestor followed by modification. Together, these forms of evidence support evolutionary relationships. Thus option A is correct; the other choices are unrelated to fossils or comparative anatomy.
