Question

Taxonomic categories were chosen at the whim of the scientist. The first scientist to try his hand at this was Aristotle. Then came Artedi and Linnaeus, but still the categories were not based on anything other than the perceptions of the scientist doing the classifying. Today, we have a more natural system of putting organisms into their taxonomic systems. We use something called systematics. What is systematics and why is it a less arbitrary and more natural approach to categorizing living organisms?

Explanation / Answer

Systematics of biology is the organized depiction of the diversification of living organisms in the past and present times, and their social relationships among living things in the course of a lifetime. In systematics, the relationships between the organisms are represented by cladograms, phylogenic trees and evolutionary trees, which are based on the morphological, evolutionary and anatomical characters orf the organisms, so it is considered less arbitrary and more natural.

Taxonomy and phylogenetics are the part of Systematics and they are complementary to each other with the following concerned themes,

1. describes scientific nomencleture for organisms,

(2) describes them,

(3) stores biological collections of them,

(4) They enable in providing classifications for the organisms, systematic ways to their identification, and saving data based on their distributions,

(5) investigates their evolutionary histories, based on their genetic deifferences.
