Nomenclature codes

Nomenclature codes are sets of rules and conventions used to give names to living organisms, fossils, minerals, chemicals, and other things in science.

Imagine you have a lot of toys, and you want to organize them in your toy box. To do that, you might give each toy a name or category based on its type or characteristics. Naming things in science is like that, but much more complicated!

There are different nomenclature codes for different things in science, but the most common ones are the International Code of Nomenclature for algae, fungi, and plants (ICN), the International Code of Zoological Nomenclature (ICZN), and the International Code of Nomenclature of Prokaryotes (ICNP).

These codes have specific rules for creating scientific names and how they are written and formatted. For instance, in the ICN, plant names are based on Latin and have two parts: the genus (a group of related plants) and the species (a specific type of plant within the genus). For example, the scientific name for the common tomato is Solanum lycopersicum, where Solanum is the genus and lycopersicum is the species name.

Similarly, in the ICZN, animal names are also based on Latin, but can have more than two parts. For example, the scientific name for the common house cat is Felis catus, where Felis is the genus and catus is the species. However, if there are subspecies, then another name is added to the end, like Felis catus domesticus for the domestic cat.

These codes ensure that scientific names are standardized and consistent across the world, making it easier for scientists to communicate with each other and making it easier to identify and study different species.
