A taxon (plural: taxa) is a term used in biology to refer to a group or category of organisms that are classified together based on shared characteristics. Taxa can range from very broad categories that include many organisms to very specific ones that include only a few. The classification system used to organize living organisms is known as taxonomy.
Here are some examples of taxa, listed from broad to specific:
1. **Domain**: The highest taxonomic rank. For example, the three domains are Archaea, Bacteria, and Eukarya.
2. **Kingdom**: A major subdivision of a domain. For instance, within Eukarya, there are kingdoms such as Animalia (animals), Plantae (plants), and Fungi (fungi).
3. **Phylum**: A group within a kingdom. For example, Chordata (animals with a spinal cord) is a phylum within Animalia.
4. **Class**: A group within a phylum. For example, Mammalia is a class within Chordata that includes all mammals.
5. **Order**: A group within a class. For example, Primates is an order within Mammalia that includes monkeys, apes, and humans.
6. **Family**: A group within an order. For example, Hominidae is a family within Primates that includes great apes and humans.
7. **Genus**: A group within a family. For example, Homo is a genus within Hominidae that includes modern humans (Homo sapiens) and their close relatives.
8. **Species**: The most specific level of classification, representing a group of individuals that can interbreed. For example, Homo sapiens is the species name for modern humans.
These categories help scientists organize and understand the relationships between different organisms in the natural world.
