2. Carolus Linnaeus He was the Swedish botanical taxonomist who was the first person to formulate and adhere to a uniform system for defining and naming the world's plants and animals. Binomial nomenclature Linnaeus published a large work, Systema Naturae (The System of Nature), in which Linnaeus attempted to identify every known plant and animal. This work was published in various sections between 1735 and 1758, and established the conventions of binomial nomenclature, which are still used today.

3. Introduction In 1813 taxonomy term was coined by A.P. de Candolle initially for plants and subsequently changed to animals. In general art of classification is called taxonomy. Arrangements of the organisms in orderly fashion. Systematic arrangements of plants and animals in particular fashion. Each species may exist in numerous different forms (sexes, age, classes, seasonal forms, morphs and other phena).

4. Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world. There are eight distinct taxonomic categories. These are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. With each step down in classification, organisms are split into more and more specific groups. It helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet. Hierarchical classification basically means that we classify groups within larger groups

5. Taxonomy is the branch of biological systematics that is concerned with naming of organisms (according to a set of rules developed for the process), identification (referring specimens to previously named taxa), and classification (ordering taxa into an encaptic hierarchy based on perceived characters

6. Modern taxonomy? Modern taxonomy is called as biosystematics. In classical taxonomy, classification is based on morphology. In modern taxonomy, classification is based on phylogenetic relationships of the organisms.... However, in modern taxonomy, the large number of individuals were studied. The main goals of taxonomy are to describe organisms with specific individual names while grouping them into a logical system.

7. Trends in biosystematics  The main aim of modern classification is not only the understanding, identification, and proper arrangement of animals but it also include the study of history of their development and evolution.  During early periods the animals were studied only on the basis of their outer structure i.e. morphology attention was paid in different species, sub-species, sub-groups etc.  Morphologic species are now called as biological species.  Now the study of animals includes the study of genetics, hereditary, biochemical and other characters along with morphological characters.  This idea provides knowledge of actual structure and history of development of species
