Classification - Systematics of Living Organisms - Biologi

Classification : 

       It is the arrangement of organisms or groups of organisms in distinct categories in accordance with a particular and we'll established plan . This classification is based on similarities and dissimilarities among the organisms.

Artificial :

 

       It is the classification that is based on few easily observable and non-evolutionary featurs such as habit, colour, form, etc., often irrespective of their affinity (relationship) with other organisms. e.g. Linnaeus system of classification.

Natural : 

       It is the classification which is based on objectively significant rather than being selected for convenience like artificial system of classification e.g. Bentham and Hooker's system of classification.

Phylogenetic : 

       It is the classification based on common evolutionary descent. e.g. Engler and prantles classification.

       In the system of classification the terms like ‘taxa' and ‘categories' are often used. Each category is referred to as a unit of classification. In fact, it represents a rank and is commonly termed as taxon.
