How do fossils and homologous organs complement each other as evidence of evolution?
Answer and explanation
Correct answer: Fossils show time sequence and homologous organs give structural clues of relationships
The governing concept is that evolution is supported by multiple, independent lines of evidence. Fossils provide a historical sequence, showing organisms and structural changes through geological time. Homologous organs, such as the forelimbs of humans and whales, share a basic structural plan despite different functions, suggesting common ancestry. Thus, option A is correct; the other options confuse evolutionary evidence with weather, sex determination, or acquired traits.
