Taxonomy vs. Classification — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on March 20, 2024
Taxonomy involves organizing living organisms into hierarchical categories, while classification refers to the process of grouping entities based on shared characteristics.

Key Differences
Taxonomy is a branch of biology concerned with the classification, naming, and identification of organisms into a structured system. It involves creating a hierarchical framework that encompasses kingdoms, phyla, classes, orders, families, genera, and species. Classification, on the other hand, is a broader concept that applies not only to biology but to various fields. It involves organizing items, concepts, or entities into categories based on shared traits or characteristics.
In taxonomy, the focus is on understanding evolutionary relationships and the natural order among organisms. This scientific discipline uses a set of rules for naming and categorizing organisms to reflect their genetic and evolutionary relationships. Classification, while integral to taxonomy, can be applied in many other contexts, such as grouping books in a library or categorizing different types of rocks in geology.
Taxonomic classification is a specific application of the broader principle of classification. It is a critical part of taxonomy, where organisms are grouped into a hierarchical structure based on their physical and genetic characteristics. In contrast, general classification might not adhere to a hierarchical structure and can be based on arbitrary or chosen characteristics depending on the context.
The principles and methodologies used in taxonomy, such as cladistics, phenetics, and evolutionary taxonomy, are specialized and tailored to understanding the complexities of biological diversity and evolution. Conversely, the methods used in general classification might be simpler and more varied, depending on the nature of the items or concepts being classified.
One of the key outcomes of taxonomic efforts is the development of a universally accepted naming system for organisms, known as binomial nomenclature, which provides a unique and standardized name for each species. In broader classification systems, the naming conventions can be more flexible and context-dependent, serving the specific needs of the field or discipline.

Common Curiosities
How does classification differ from taxonomy?
Classification is the broader process of grouping entities based on shared characteristics, whereas taxonomy is a specific branch of biology focused on classifying organisms.
Why is taxonomy important in biology?
Taxonomy helps scientists understand the diversity of life, evolutionary relationships, and provides a universal system for naming organisms.
What is taxonomy in biology?
Taxonomy is the science of classifying, naming, and identifying organisms within a hierarchical system, reflecting their evolutionary relationships.
What are some methods used in taxonomy?
Methods include cladistics, which focuses on common ancestry, phenetics, based on overall similarity, and evolutionary taxonomy, which considers both.
What is binomial nomenclature?
Binomial nomenclature is a system used in taxonomy to give each species a unique, two-part Latin name indicating its genus and species.
Can classification be used outside of biology?
Yes, classification is used in various fields to organize items or concepts, such as categorizing books in a library or types of rocks in geology.
Is the classification system always hierarchical?
In taxonomy, it is hierarchical, but in other contexts, classification systems can be hierarchical or non-hierarchical.
Can the same principles of taxonomy apply to classifying non-living things?
While the principles of taxonomy are specific to biological organisms, the general concept of classification can apply to non-living things, using different criteria.
How does taxonomy reflect evolutionary relationships?
Taxonomy groups organisms in a way that reflects their common ancestry and evolutionary paths, using characteristics derived from evolutionary biology.
How does classification help in everyday life?
Classification helps in organizing information, making sense of diverse items, and improving accessibility, such as categorizing products in stores or files in a computer.
