Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.

Hence, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

In taxonomy, species refers to the basic unit of naming that includes members such as mammals and reptiles with the ability to reproduce with each other to birth new offsprings and exchange genetic informations. Some examples of species include Homosapiens, Vulpes, Elephas maximus, Pinus banksiana, Alces laces, Ursus americans, Canis lupus, etc.

Speciation is considered to have occurred in a species population once one species migrates to a different geographical location than another species.
