1.	How do fossils help us in understanding the evolutionary history?
Answer» Paleontological evidences • The study of fossil is called paleontology. • Fossils are the remains or impressions of past organisms preserved in sedimentary rocks or other media. • Different-aged rock sediments in earth’s crust indicate the presence of fossils of different life forms which died during the sediment formation. • A variety of fossils ranging from the modern organisms to extinct organisms can be observed. • By studying the different sedimentary layers, the geological time period in which the organism existed can be predicted.
