why do we classify things in science

In biology, all living organisms are classified according to eight different categories. These are:
Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. This can be easily remembered through the mnemonic device, Did King Phillip Come Over For Great Spaghetti. You simply take the first letter of each word and apply it to the taxonomic category. Domain is a fairly new rank in the taxonomic scale and isn't yet officially recognized, but is being included more and more in papers and books. With this classification system, we end up with a better understanding of what the relationship between organisms might be. If you notice one organism is from a specific family, you can guess what others might be from the same family and how they might end up classified near each other. It also allows us to see the idea of evolution in full force.

You can see where the organisms all started and where they wound up. Organization is key to science, since it helps us better understand the world around us. In order for us to expand upon our ideas in science, we need classification, which puts them in specific categories so we know immediately what they do and how they are different from other objects. Biological taxonomy, which is basically the scientific classification system that we use, is broken into eight ranks. These include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. An easy way to remember this is the acronym Did King Phillip Come Over For Great Spaghetti, where each category name is represented by their first letters. Prerequisites Data or evidence For every object or organism to be classified, a lot of information is needed.

This data is usually provided by systematics ; an examination of organisms from many points of view. Such data can include input from almost all fields of science, including molecular biology, field studies, collections, morphological analysis, genetics, behavioral studies, chemistry, and anatomy. A systematic study, at its best, generates a very large amount of data about organisms which can then be used to determine the range of similarities and differences between them. The appropriate groups Taxonomy is a theoretical branch of biology in which taxonomists try to devise appropriate groups into which they can unambiguously place all living things. All taxonomies start from first principles; now do the groups relate to one another?

Is it a structural relationship, evolutionary relationship, or even a ecological relationship? Taxonomies also have rules and procedures that must be followed during their use. Agreed names The nomenclature used when naming the individual species and groups must be distinctive, unambiguous and agreed upon by all users. It must be universal and adopted by scientists everywhere in the world. Process and Priorities Once the evidence is in and the taxonomy agreed, individual species must find their way into the appropriate groups. Classification in Biology depends on users agreeing on the principles of how this should be done (process) and what features of a species or process receives the higher priority when difficulties arise. For example, are structural or ancestral factors paramount?
