Aim of classification are- To acquire knowledge of every group and subgroup of each organism. To introduce the total knowledge concisely. To take proper steps after identifying organisms to name them. To conserve the species for the well-being of human beings and the living world.
On the basis of each other’s similarity and dissimilarity, grouping organisms into groups and subgroups is called classification. Swedish botanist Carolus Linnaeus (1707 – 1778) first introduced complete classification and naming of organisms. So he is called the father of taxonomy. He first classified the living world into two kingdoms – Plant and Animal.
There are seven ranks for classifying an organism in species level according to international code. They are: Kingdom → Phylum / Division → Class → Order → Family → Genus → Species.
