How does studying fossils and homologous organs together strengthen understanding of evolution?
Answer and explanation
Correct answer: Fossils provide evidence through time, and homologous organs suggest evolutionary relationships.
Fossils provide a time-ordered record of organisms and can reveal changes in forms that lived in the past. Homologous organs have a similar basic structural plan, even when their functions differ, suggesting common ancestry. When both types of evidence are considered together, they support change over generations and relationships among organisms. Thus option A is correct; the other choices confuse evolutionary evidence with feeding, acquired traits, or sex determination.
