Consider statements about evolution: 1. Fossils provide evidence of past life. 2. Homologous organs indicate common ancestry. 3. Analogous organs indicate common ancestry. Which are correct? MCQ with Answer and Explanation

Fossils are the preserved remains or traces of ancient organisms, providing direct, chronological evidence of evolutionary changes and past life forms over millions of years. Homologous organs (like the forelimbs of humans, whales, and bats) share a common structural plan and evolutionary origin, indicating divergent evolution from a common ancestor. Analogous organs (like the wings of birds and insects) perform similar functions but have different structural plans and evolutionary origins, indicating convergent evolution, not common ancestry. Thus, statements 1 and 2 are correct.
