Question

What is evolution and classification?

Answer 1

Evolution is change in the heritable characteristics of biological populations over successive generations. Evolutionary processes give rise to biodiversity at every level of biological organisation including the levels of species, individual organisms, and molecules.
Organisms differ in their form, structure and mode of living. Hence, based on their similarities they should be grouped. The grouping of related organisms helps us in studying their evolutionary relationships.
Classification is the division of organisms on the basis of characteristics into groups and sub-groups. A characteristic may be a particular form or function. For example, classification of animals can be done based on some criteria.
