Classifications and evolution are interlinked |
|
Answer» 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.Criteria for classification:\xa0Animals are classified on the basis of different features.*Cellular or tissue level of body organisation.*Body symmetry.*Type of body cavity called as coelom.*Presence or absence of segmentation.*Presence or absence of a backbone.Evolution:\xa0It is the sequence of gradual changes over millions of years in which new species are produced. Classification of species is done by knowing the characteristics which evolved over a long period of time. Evolution are the slow nd gradual changes which lead to the formation of new species. To study it more conveniently v classify the species on different basis.. So as to know more about their origin becomes easy.. |
