Question

Fossils as evidence of Evolution....short notes

Answer 1

Branch of science that deals with fossils is called palaeontology. Fossils are remnants of plants and animals or their parts and impressions in the form of rocks in the crust of earth. The fossils were formed in the long past when earth containing organisms was covered with rocks. The process of formation of fossils is called fossillisation or petrification.

The fossils formed at different geological times were buried in the sedimentary rocks deposited during that period. The organic materials were gradually converted into inorganic compound and ultimately changed into rocks. The earliest fossil discovered was formed 900 million years ago. They were fossils of uninucleate plants and animals.
