CLASSIFICATIONWHAT IS CLASSIFICTION ?

Classification is a method of scientific

taxonomy used to group and categorize organisms

into groups.

The first person to classify organisms into different groups was ARISTOTLE.

He classified organisms according to their habitat. As the organism live on land, water

or in the air.

BASIS OF CLASSIFICATION

The classification of organisms is based on such features or characters, which are similar in one kind of organisms and

different in different kind of organisms.

EVOLUTIONWHAT IS EVOLUTION?Biological evolution is defined as any genetic change in a population that is

inherited over several generations.

The origin of species was the book in which CHARLES DRAWIN first described the idea of

evolution in 1859.

NOMENCLATUREThe scientific name for an organism is unique and can be used to identify it anywhere in the

world. The system of scientific naming or nomenclature we use today was introduced by

Carolus Linnaeus in the eighteenth century. The scientific name of an organism is the result

of the process of classification which puts it along with the organisms it is most related to.
