Question

Explain the importance of fossils in deciding evolutionary relationships.

Answer 1

Fossil provide us evidence about

• The organisms that lived long ago such as the time period during which they lived, their structure etc.
• Evolutionary development of species i.e., line of their development.
• Connecting links between two groups. For example, feathers present in some dinosaurs means that birds are very closely related to reptiles. 
• Which organisms evolved earlier and which later.
• Development of complex body designs from the simple body designs.
