how are the areas of study - evolution and classification - interlinked?
Evolution and classification are linked in the following ways--->
1. Classification can be carried out when evolution is traced out.
2. Evolution traces helps in a lot of classification
3. It helps to study both the areas interlinked.
4.It defines the hierarchy of an organism from its beginning
Fact-----> If you study about evolution it is obvious you will get about classification...
Hope it helps!!!

Evolution: Most of the life forms that we see today have arisen from the accumulation of changes in the body design of ancient organisms. This slow change in the body design of an organism over a long period of time is termed as evolution. It helps an organism to survive in its surroundings. Classification allows things to be identified and categorized on the basis of structure and function of an organism, and accordingly, we can refer to them as primitive or advanced organisms. Therefore, classification helps in predicting the line of evolution.

ANS: Classification of an organism is done on the basis of relative similarities and differences present in them. They are similar because they have arisen from common ancestors and differences in them is due to adaptation to different types of environment .The classification shows the orderly increase in the complexity of the organisms which indicate the concept of evolution.Thus both these terms are interlinked.

Classification involves grouping of organism into a formal system based on similarities in internal and external structure or evolutionary history.
Two species are more closely related if they have more characteristics in common. And if two species are more closely related, then it means they have a more recent ancestor.
For example, in a family, a brother and sister are closely related and they have a recent common ancestor i.e., their parents. A brother and his cousin are also related but less than the sister and her brother. This is because the brother and his cousin have a common ancestor i.e., their grandparents in the second generation whereas the parents were from the first generation.
With subsequent generations, the variations make organisms more different than their ancestors.
This discussion clearly proves that we classify organisms according to their resemblance which is similar to creating an evolutionary tree.

Living organisms are identified and grouped according to their body design in relation to their form and function. Some characteristics are likely toi make more wide-ranging changes in body design than others. There is a roleof time in this as well. So once a certain body design comes into existence, it has an effect on allother succeeding design changes, since it already exists. Thus characteristics that came into existence earlier are more fundamental those which come into existence later. Thus classification of life forms is closely related to their evolution. Most life-forms seen today have arisen by an accumulation of changes in body design that allows the organism possessing them to survive better.
When the idea of evolution is connected to classsification, it can be seen that some organisms with ancient body designs have not changed much whereas other organisms have evolved their particular body designs relatively recently.

for eg : classification of homologous organs show that organisms which have organs of similar structures but different functions are to be evolved from a common and more recent ancestor.similarly orgainisms which have organs that have similar functions but different structures are to be closely related to each other.
the study of evolution has shown how different structures have evolved and perform different functions. for eg: birds used feathers for protecting themselves from the cold weather but now wings are used for flying.
the study of evolution has also shown the amount of time taken for the development of new species and organs and molecular phylogeny helps us understand the development and variations that took place in the dna which lead to such variations.

- different forms of organisms are have evolved during the course of evolution,and classification deals with grouping of these organisms into groups and subgroups based on similarities and difference
- the more characteristics any two species have in common more closely they are related
- thus classification helps in tracing the evolutionary relationships between the two organisms

CLASSIFICATION: The process of grouping the individuals into different kingdoms, classes. groups etc for better study of biodiversity
Therfore, classification is due to evolution

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.
Evolution: It 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.
