Following are the various pieces of evidence in favour of evolution:
- Analogous Organs
Organs that have different basic structures but perform similar functions are known as analogous organs. For example, the wings of a bird and the wings of an insect have different anatomy but they perform the same function of flying in the air.
- Homologous Organs
Organs with common basic structural design but with different functions are known as homologous organs. For example, forelimbs of a lizard, man, bird and frog.
- Evidences from fossil
Fossils provide evidence for evolution. The fossil Archaeopteryx looks like a bird but it shows a number of other features, that are found in reptiles. This observation provides a clue that birds have evolved from reptiles.
