Question

evolution and fossils are interlinked justify

Answer 1

The fossil record. Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.

Answer 2

the classification of organisms is a reflection of their evolutionary relationships. Classification is based on similarities and differences amongst organisms: the more characteristics 2 organisms have in common, the more closely they are related and the more recently they will have had a common ancestor in the evolutionary chain, the more different characteristics 2 organisms have, the more remotely they are related and they will have had a common ancestor in the more remote past

or

Every species or organisms has inbuilt tendency for genetic variation which plays an important role in the origin of new species and forms the the basis for evolution.The more characteristics two species have in common, the more closely they are related. And they are likely to have a a common ancestor more recently. Classification of organisms necessarily involves, organizing them in different groups, based on the similarities and differences of characteristics. Classifying organisms helps us in recognizing the basic arrangement of a hierarchical structure among diverse species. So, classification of species is a reflection of their evolutionary relationship. Thus, we can say that evolution and classification are interlinked.
