1. Two-part name:
* Genus name: The first part of the name is the genus, written with a capital letter.
* Species name: The second part is the species, written in lowercase.
* Example: *Homo sapiens* (humans)
2. Italics:
* The entire scientific name is always italicized, or underlined if italics are not available.
3. Author abbreviation:
* The name of the person who first described the species may be included after the species name, usually abbreviated. This is optional, but helpful for scientific accuracy.
* Example: *Homo sapiens* Linnaeus (1758)
4. Subspecies:
* If a subspecies is identified, a third part is added after the species name, also italicized.
* Example: *Canis lupus familiaris* (domestic dog)
5. Common names:
* While common names may be used, scientific names are preferred in formal scientific writing.
Examples:
* *Panthera leo* (lion)
* *Quercus rubra* (red oak)
* *Escherichia coli* (a type of bacteria)
* *Tyrannosaurus rex* (a dinosaur)
Note:
* The scientific name should always be written in full the first time it is used in a document. After that, the genus name can be abbreviated with a single initial (e.g., *H. sapiens*).
* It's important to use the correct and current scientific name. Scientific classification can change as new research is conducted.
