Classification System of Biology To know the Biology classificatio System is very important for every science student for better understanding the subject. About four million of different plant species and thirteen million of animal species have been named and described till today. The number is not yet final because the description of more and more new species is being added to it almost every day.

Classification System of Biology

It is assumed that the number will reach a crore in future when the description of all the organisms will be ended. A large number of organisms are needed to be grouped systematically for the convenience to know, understand and learn them. Many years back natural scientists felt the necessity to classify living world following a natural system. From this very necessity, a distinct branch of biology, taxonomy had emerged.

The aim of classification is only one to know the vast and diverse living world accurately and classify them with little effort in a short period of time. The contribution of Swedish botanist, physician and zoologist Carolus Linnaeus (1707-1778) in the field of taxonomy is more worth mentioning. In 1735 at the age of 28, he took his doctoral degree in medicine at the University of Harderwijk, and in 1741 he was appointed Professor of Medicine at Uppsala University.

Though he was first responsible for medicine-related matters, soon he changed his position with the other Professor of Medicine to become responsible for the Botanical Garden, botany and natural history instead. He thoroughly reconstructed and expanded the Botanical Garden. It was the main field of his intense interest to classify organisms from his botanical and zoological observations that he assembled from his many expeditions.

He classified living world into two kingdoms – Plant and Animal. In 1953 Linnaeus published his book Species Plantarum which is internationally accepted as the starting point of modern botanical nomenclature and in 1958 he released the tenth edition of his book Systema Naturae which established itself as the starting point for zoological nomenclature. He first defined the term genus and species in his book. Based on the observations of size, structure and characteristic, plants and animals are named. On the basis of each other’s similarity and dissimilarity, grouping organisms is called classification.

Aim of Biology Classification System

The aim of classification is to acquire knowledge of every group and subgroup of each organism. To document the accumulated information systematically focusing on the diversity of living organisms, introduce the total knowledge concisely and take proper steps after identifying organisms to conserve them or increase the number of species for the well-being of human beings and the living world are the objectives of classification.

Q: Why classify?

A: Because, it helps to understand things under the complexity of biological diversity One and half million types of organism have been discovered on this planet and it has been estimated that there may be 10-100 million kinds of organisms.

Q: How Classification Began?

A: Classification began By ancient people that observed nature and had a desire to organize the knowledge gained. Classification- the grouping of objects based on similarities ex:: baseball cards, coins, shoes, etc Ancient Chinese classification of dogs Stray Dogs Those have broken flower vase Resemble flies at a distance.
