1-these are the dead remains of earlier organisms who got buried under the earth..
2-By studying fossils we can also identify the time of formation.
3-Taking an example of ARCHIEOPTARIX's skeleton,studing This skeleton tell that the birds are arises from reptiles.

Fossils provide us to know any link between different species of organisms.
ii-Fossils help in establishing evolutionary traits among organisms and their ancestors.
iii-Fossils help in establishing the time period in which organisms lived.
(b)The system of taxonomy is based on evolutionary and genetic differences. Evolutionary relationships are reflected in taxonomy. Taxonomy is an artificial, hierarchical system showing categorical relationships between species based on specific defining characteristics. Each level within the taxonomic system denotes a greater degree of relatedness to a particular organism if it is closer in the hierarchical scheme. Taxonomy such as evolutionary taxonomy helps to classify organisms on the basis of ancestral relationships. It also gives the detail of evolutionary changes as well as the progenitor-descendant relationship.
