Question

How does Evoultion and classification of organisms go hand in hand

Answer 1

In this world, there are numerous species known and unknown to us. For the ease of study and identification of organisms, they have been classified into different groups based on different criteria. We know body design is one of the criteria for biological classification. Every classification started with a basic design. Once there was only one body design, with the time design changes. Later, organisms with new body design may be more advanced ones, came into existence. Thus we can say, there is a thin line that connects classification and evolution of species.

Classification is based on similarities and differences among organisms. Organisms having same type of features and level of development are kept in same class. Organisms resemble with each other because if we trace back their origin we find that they were developed from common ancestors.Evolution means studying organisms based on the complexity of their structure and features and arranging them in order of their complexity. So it is evident that both classification and evolution are interlinked

1. Similarity among 2 species allows us to group them together and study their characteristics.
2. The more characteristics the groups have in common, the more closely they are related.
3. The more closely the groups are related, the more recently they will have had a common ancestor.
Thus, classification of species is a reflection of their evolutionary relationship.
