A3.1.3 Binomial system for naming organisms Notes
Two Parts To The Binomial System
Definition
Binomial name
A binomial name is a two-part Latinized name that uniquely identifies a species. The first word represents the genus, and the second word represents the specific species within that genus.
The binomial system gives every species a unique two-part name, ensuring consistent identification.
It consists of:
Genus name: The first part, which groups closely related species.
Species name: The second part, which specifies the exact species.
Example
Homo sapiens:
Homo: The genus grouping humans with extinct relatives like Homo neanderthalensis.
sapiens: The species name identifying modern humans.
Formatting Rules
Italicize when printed, or underline when handwritten.

Note
The binomial system is a standardized method for naming organisms that ensures each species has a unique and universally recognized name. This system consists of two main parts:
The Genus name, which groups closely related species, and
The Species name, which identifies the specific organism within that genus.
DefinitionThe binomial system is a universal naming method that gives every organism a unique two-part name.
ExampleIn Homo sapiens, Homo is the genus name, and sapiens is the species name. This distinguishes humans from other species like Homo neanderthalensis (Neanderthals).
AnalogyThink of the binomial system like a person's last name and first name: the last name (genus) groups family members, while the first name (species) identifies the individual.
