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

Explanation

The remains (or impressions) of dead animals or plants that lived in the remote past are known as fossils . The fossils provide evidence for evolution. For example, a fossil bird called Archaeopteryx looks like a bird bot it has many other features which are found in reptiles. This is because Archaeopteryx has feathered wings like those of birds but teeth and tail like those of reptiles. Archaeopteryx is, therefore, a connecting link between the reptiles and birds, and hence suggests that birds have evolvel from the reptiles. Thus, fossils provide the evptilce that tha present animals (and plants) have originated from the previously existing ones through the process of continuous evolution.
