Binomial nomenclature is a standardized system for naming and classifying living organisms, facilitating precise scientific communication. Developed by Carolus Linnaeus in the 18th century, it utilizes a hierarchical classification system with names derived from Latin and written in italics. Key rules include the uniqueness of names within a genus and the requirement for formal publication in scientific literature.

Introduction
 Binomial nomenclature is the standardized system
used to name and classify living organisms.
 It provides a universal language that allows
scientists to communicate about the natural world
with precision and clarity.
 The first part of the name identifies the genus, while
the second part identifies the specific species within
that genus.

History
Carolus Linnaeus
 In the 18th century, Swedish botanist Carolus
Linnaeus proposed a standardized binomial naming
system that revolutionized the way living
organisms were classified.

Principles
Taxonomy
 Binomial nomenclature is based on the hierarchical
system of biological classification, which groups
organisms by their evolutionary relationships.
Latinized Names
 The genus and species names are derived from Latin ,
providing a universal scientific language.
 Italicized Format
 Binomial names are typically written in italics to
distinguish them from common names or descriptive text.

Rules for Naming Living Organisms
Internationality
 Binomial names must be recognized and used by the global
scientific community.
Publication
 New species must be formally described and published in
scientific literature.
Regulations
 Naming conventions are governed by the International Code of
Nomenclature.
Uniqueness
 Each binomial name must be unique within its respective genus.
