There have been many attempts to classify living organisms since ancient times. Aristotle was the earliest to attempt a scientific basis of classification. He used simple morphological characters to classify plants as trees, shrubs and herbs. He also classified animals into two groups,i.e„ enaima (with red blood) and anaima (without red blood). A need for proper system of classification was always felt. @ @vidyawiseofficial @vidyawiseofficial @scerttn @SCERTDelhi @SCERTDelhi @scertmanipur6144 @swarnimbiologyclassesbyshubham
