Taxonomy is a branch of science that deals with the classification of living and extinct organisms. It arranges them into hierarchies of superior and subordinate groups. (Oxforddictionaries.com, (2014), Encyclopedia Britannica, (2014)). The classification of organisms is extremely important due to the vast range of life forms that exist. Many scientists classify these organisms to help establish an organization in order to study them more competently. It also allows you to identify and investigate relationships between organisms. Without these systems it is not possible to follow the evolution of organisms and its history. The first identified classification system was created by Aristotle, a Greek philosopher born in 384 BC. This classification system divided organisms into two basic groupings; plants and animals (Utahscience. (2012)). His system, however, was not without flaws and over time new systems were produced in an attempt to revolutionize the classification system. Furthermore, these modern systems were greatly influenced by the evolutionary theory of natural selection identified by Charles Darwin. Today, the classification system is based on Carol Linnaeus' two-kingdom system, otherwise known as the binomial system (Eclp.com.na. (2013). Due to different opinions among scientists, it is difficult to classify an organism into a particular catalog and therefore many use alternative versions of the current classification system. It is very important to implement a universal model to keep track of organisms, their relationship with other organisms and the environment and their history the strengths and limitations of each model. must be carefully evaluated.Also... half of the article ......the range of life that exists today The taxonomic system has evolved over time, from Aristotle's basic plant and animal system to Linnaeus's binomial system shows how technology has revolutionized it, identified new organisms, and reclassified others. Other systems have been identified over time, including Theophrastus' plant classification key, three-, four-, five-, and six-kingdom systems, as well as cladistic analysis. , phenetics and evolutionary systematics. . It was emphasized that it is necessary to implement a universal system to avoid confusion among scientists and organize research efficiently. The model that would be best implemented universally would be cladistic analysis since it combines both phylogeny and the evolution of morphological characteristics. Since no model can be perfect, cladistic analysis should weave the binomial system to create a more efficient model.
