Q.:- Which organisms are called primitive and how are they different from the so called advanced organisms?

 

Answer:-

The organisms which have ancient body designs that have not changed much are called primitive organisms or lower organisms. These are simple life forms. On the other hand, the organisms that have acquired their particular body designs relatively recently, they are called advanced organisms or higher organisms. These are more complex life forms.
