Why is the classification done by Linnaeus called 'artificial'?

Correct answer: Because it was based on only one or a few superficial characters

Direct answer: B is correct. Linnaeus’s system is called artificial because it grouped organisms mainly on the basis of a small number of easily observed characters rather than their complete natural relationships or evolutionary history. In plants, features such as the number and arrangement of stamens were important in his sexual system. Such characters were useful for identification, but they could place unrelated organisms together or separate closely related ones. A is wrong because “artificial” does not mean the work was performed in a laboratory; it refers to the basis of classification. C is wrong because the system was systematic and historically important, even though it had limitations. D is wrong because Linnaeus did use definite rules and criteria. Memory cue: artificial classification means “few selected external characters,” whereas natural classification uses many characters and natural affinities.
