Latin is often considered a dead language because it is no longer used as a means of daily communication. However, Latin continues to play a crucial role in the scientific world, particularly in biology. Latin serves as the foundation for the classification system known as Binomial Nomenclature.
In addition to facilitating the identification and classification of species for scientists, this system also ensures that scientific names are consistent worldwide.
According to a report from the Royal Botanic Gardens, Kew in the UK, there are currently around 391,000 known vascular plant species. About 369,000 species, or approximately 94 percent, are flowering plants.
Each year, approximately 2,000 new plant species are discovered or described, many of which are on the brink of extinction.
For animal species, estimates reach around 2.16 million, based on various sources like the World Animal Foundation and Live Science. This number is part of an estimated 8.7 million species on Earth, including plants, fungi, and animals.
Let’s explore further how Latin is used in biological classification.

ToggleHistory and Origin of Latin in Biological Classification
Latin originated from the Latium region in Italy and became the official language of the Roman Empire. Although no longer used in everyday conversation, Latin remains alive in various forms, especially in science.
The use of Latin for biological classification began in the 18th century when Carl Linnaeus, a Swedish scientist, developed the Binomial Nomenclature system. Linnaeus introduced this system in his famous work, “Systema Naturae.”
Linnaeus’s Binomial Nomenclature system uses Latin names to provide a unique and universal identity to each species. Scientific names consist of two parts: genus and species.
The use of Latin names ensures that these names are not influenced by local languages or dialects, making communication among scientists from different parts of the world easier.
Binomial Nomenclature System: Structure and Benefits
The Binomial Nomenclature System is a method used to give scientific names to animal and plant species. This system consists of two parts:
- Genus: The first name, indicating a species group with similar genetic and morphological characteristics. The genus name is written with an initial capital letter.
- Species: The second name, specific to each species within the genus. The species name is written in lowercase and follows the genus name.
An example of a scientific name is Homo sapiens for humans, where Homo is the genus name and sapiens is the species name.
Benefits of the Binomial Nomenclature System
Here are some benefits of the Binomial Nomenclature System:
1. Global Uniformity
The binomial nomenclature system provides a consistent scientific name for each known species, avoiding confusion caused by different local or common names across various countries or languages.
For example, the scientific name for the domestic cat is Felis catus. This name is used worldwide to refer to this species, preventing confusion among different common names like “cat” in English, “chat” in French, or “gato” in Spanish.
2. Ease of Identification
By using only two words—the genus name and the species name—the system simplifies the identification and classification of organisms. Scientists and experts around the world also find it easier to communicate with one another.
For example, the scientific name for the harbor seal is Phoca vitulina. Knowing the genus (Phoca) and species (vitulina) helps scientists easily identify the harbor seal and understand its position within the pinniped taxonomy.
3. Systematic Grouping
This system allows organisms to be grouped scientifically based on shared characteristics. It facilitates studies on evolutionary relationships and comparisons between species.
For example, the scientific name for humans is Homo sapiens. This name classifies humans within the genus Homo and the species sapiens. This classification helps scientists study the evolutionary relationships between humans and other species within the genus Homo, such as Homo neanderthalensis (Neanderthals).
4. Avoiding Duplication
The binomial system avoids using identical names for different species, reducing the likelihood of confusion or errors in research and scientific documentation.
5. Important for Scientific Documentation
Binomial names are widely used in scientific literature, research, and publications, helping ensure that all references to a species refer to the same organism.
Examples of Latin Names in Animal and Plant Classification
To understand further, let’s look at some examples of Latin names in animal and plant classification.
