1) Homologous organs - These are organs of two different species having same basic structure but different functions. Example - Forelimbs of man and lizard.
Having same basic structure, they show that both the species have evolved from a common ancestor.
2) Analogous organs - These are organs of two different species having different body designs but same function. Example - Wings of birds and butterfly.
These point out that evolution had occurred when both the species faced a common difficulty like the need to fly.
3) Fossils - They show evidences of evolution by enabling us to study older life forms and comparing them by modern life forms. Example - The fossils of Archaeopteryx, a prehistoric bird contains both wings and jaws having teeth. This shows that birds and reptiles had a common ancestor from which they evolved.
