Classification is the process of identifying and grouping objects or ideas into predetermined categories. It is a division or category in a system that divides things into groups or types. In the context of living organisms, classification is based on basic, shared characteristics, and organisms within each group are further divided into smaller groups based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together.
Classification is used in various fields, including data management, where it is used to group data into categories. In addition, classification is used in government job classifications for workers. The need for classification arises from the need to organize and understand information, objects, or organisms.
In taxonomy, which is the science of naming, describing, and classifying organisms, taxonomists classify all organisms into a hierarchy and give them standardized names. The levels of classification include domain, kingdom, phylum, class, order, family, genus, and species. The smallest unit of classification is a species, which is a group of organisms that can interbreed and produce fertile offspring.
