Question

Difference between classification based on phylogeny from an artificial classification based on appearance

Answer 1

Answer:

• The major difference between artificial and phylogenetic system of classification is that in phylogenetic system we take the evolutionary history of the organisms is taken while in artificial system it is not considered.

Explanation:

• In the artificial system of classification of organisms the external appearances are taken to classify organisms, while in phylogenetic system external appearances are not important.

• In this system both vegetative and sexual characters are considered, while in phylogenetic systems only sexual characters are taken into consideration because vegetative characters are more liable to change with the changing environmental factors.

• In phylogenetic system the evolutionary history of organisms and their gradual evolution process is taken into consideration while in artificial system it is not considered.

• Phylogenetic system places the least evolved organisms in the bottom of the classification while the most advanced group of organisms requires the highest position.

• Example of Artificial system Bentham and Hooker's system of classification.

• Example of Phylogenetic system: R.H. Whittaker's system of classification.
