1. Genus: The first part of the name, which groups the species with other closely related species.
2. Species: The second part of the name, which specifies the particular species within the genus.
For example, the scientific name for humans is Homo sapiens. "Homo" is the genus, and "sapiens" is the species.
This system of binomial nomenclature was developed by Carl Linnaeus in the 18th century. It helps scientists all over the world to communicate about animals in a clear and unambiguous way, regardless of language barriers.
