Binomial nomenclature by Carl Linnaeus:
Binomial nomenclature is a system developed by the scientist Carl Linnaeus to give each living organism a unique scientific name. Just like how we use first and last names to identify people, binomial nomenclature uses two parts to name an organism: the first part is the genus, and the second part is the species. This system helps scientists all over the world to avoid confusion and to know exactly which organism is being referred to.
For example:
- The scientific name for a domestic cat is Felis catus (where Felis is the genus and catus is the species).
- A mango tree is called Mangifera indica.
| Living Things | Scientific Name |
|---|---|
| Dog | Canis lupus familiaris |
| Cow | Bos taurus |
| Hibiscus | Hibiscus rosa-sinensis |
| Jowar | Sorghum bicolor |
This naming system ensures that even though animals or plants may look different or live in different places, they are recognised as part of the same species if they can reproduce and create offspring. The rules for naming organisms are set by an international body called the International Code of Nomenclature.
