Understand how species and genus serve as the foundational levels in the hierarchical system used to organize and name living organisms.
As one moves from species towards kingdom, the categories become broader and include more organisms, while the number of common characteristics decreases.

The abbreviated author name written after the specific epithet indicates the scientist who first described the species. “Linn.” indicates Linnaeus.

All three names contain the generic name Solanum but have different specific epithets. They therefore represent different species belonging to the same genus.

All three names contain the generic name Solanum but have different specific epithets. They are therefore different species belonging to the same genus.

Humans belong to the family Hominidae, order Primata, class Mammalia and phylum Chordata. Therefore, Primata and Mammalia occur between Hominidae and Chordata.

The genus Panthera includes closely related species such as lion, leopard and tiger, represented by the specific epithets leo, pardus and tigris.

Species is the lowest and most specific taxonomic category. Its members share more characteristics than members grouped at higher taxonomic levels.

The generic name begins with a capital letter, whereas the specific epithet begins with a small letter. When handwritten, the two words are underlined separately.

The genus Solanum includes several related species with different specific epithets, such as tuberosum, melongena and nigrum.

Humans belong to the genus Homo, family Hominidae and order Primata. Therefore, Hominidae lies between the genus and order.

A taxon is a unit of classification representing a rank or category. Species, genus, family and class are taxa at different hierarchical levels.
