Question

What are the difficulties that you would face in classification of animals, if common fundamental features are not taken into account?.​

Answer 1

hey mate...

here is your answer...

For the classification of living organisms, common fundamental characteristics are considered. If we consider specific characteristics, then each organism will be placed in a separate group and the entire objective of classification would not be achieved. Classification of animals is also important in comparing different organisms and judging their individual evolutionary significance. If only a single characteristic is considered, then this objective would not be achieved.  

hope it helps...

Answer 2

Explanation:

Using the common fundamental features helps in segregating the animals in different groups. Let us take the example of presence or absence of notochord.
