Question

Explain why evolution and classification are interlinked? Plz tell detailed answer for 3 marks..

Answer 1

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: Animals 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.

Answer 2

evolution: an organism with a new character that specifies it
classification: the organised manner of keeping the organism in its group where similar such organism are present
now a organism B is having suppose F G I character now evolution takes place so in the B organism F G I and K character is added it cannot be placed in the same group it has removed or classified
