What are the three types of classification systems?
✓
Answer
The three types of classification systems are:
(i) Artificial system:
(a) It is based on few visible, easily observable characters, which are non-evolutionary such as habit, colour, form, etc.
(b) It does not consider the affinities (relationships) among different organisms.
E.g. Linnaeus system of classification.
(ii) Natural system:
It is based on objectively significant characters with respect to their affinities with other organisms.
E.g. Bentham and Hooker’s system of classification.
(iii) Phylogenetic system:
It is based on the phylogenetic relationship between different organisms with respect to common evolutionary descent (ancestor).
E.g. Engler and Prantl’s classification.
