| 1. | Wings of bats and wings of birds, as both evolved from a common ancestor. |
| 2. | Flippers of whales and fins of sharks, as both are adaptations for swimming but have different evolutionary origins. |
| 3. | Forelimbs of humans and forelimbs of lizards, as both have the same skeletal structure. |
| 4. | Legs of frogs and hindlimbs of rabbits, as both belong to vertebrates. |

| 1. | conducted a control experiment to disprove spontaneous generation |
| 2. | proposed the concept of pangenesis as the physical basis of heredity |
| 3. | disapproved the proposal of Ernst Haeckel [Biogenetic law] |
| 4. | was one of the rediscoverers of Mendel’s laws |
| 1. | Homologous structures indicate that different species evolved from a common ancestor but adapted to different environments over time. |
| 2. | Homologous organs perform the same function in different organisms, showing that all life forms evolved in a similar manner. |
| 3. | Homology refers to similar structures in unrelated species, proving that all organisms evolved independently. |
| 4. | Homologous structures arise due to similar environmental pressures, leading to organisms acquiring identical adaptations. |
