5.1

Taxonomy is the classification of organisms in an ordered system that indicates natural relationships. The system currently used by taxonomists. The classification levels become more specific towards the bottom.




 Kingdom > Phylum > Class > Order > Family > Genus > Species


Biological classification systems have two main purposes.
1) Identifying organisms
2) Providing a basis for recognizing natural groupings of living things


Carl Linneaus created the present bioligical system of classification. His system was based on an organism's physical and structural features and operating on the idea that the more features in common, the closer the organism had a relationship among other organisms.


Binomial nomenclature is a method of naming of naming organisms by using two names. The genus name and the species name. Scientific names are italicized. Latin being the common language for all scientists are used for naming organisms.




Carl Linnaues, a swedish botanist, based his system on the physical and structural features of an organism. All living organisms are divided into 5 Kingdoms: Plants, Fungi, Animals, Protoctista and Bacteria.

Eg. Birds are in the Animalia Kingdom, are in the Phylum of Chordata, and Class Aves 


At the Order level the birds beginning to diverge and group into separate orders. The Sparrow Order is Passeriformes and the Parrot Order is Psittaciformes.
