What are fossils? What do they tell u about the process of evolution?

Dear Student

Preserved traces of living or dead organisms on solid hard surface is called fossil. Fossils help us to know the evolution, If a fossil is found closer to the surface of earth, then it is more recent in origin than the fossils we find in deeper layers. Fossils, like Archaeopteryx, help us to find evolutionatzy relation between organisms.

Thanks
