प्रश्न
What is basis of classification?
उत्तर
The classification of organisms is based on their body design in relation to their form and function. For instance, some characteristics have more wide-ranging changes in the body design of different organisms than other characteristics. Another factor that influences classification is the evolution of characteristics with time. The characteristics that came into existence earlier are usually considered to be more fundamental than the ones that came later.
