Taxonomy

Study of principles and procedures of classification

Each scientific name has two components

Generic name + Specific epithet

Family name of animals generally end with

' idea' suffix

Family name of plants generally end with

'acea' suffix

Family Solanaceae includes the genus

Solanum, Petunia and Datura

Family Felidae includes the genus

Panthera and Felis

Family Canidae includes the genus

Canis (dogs)

Eg

Plant families like Convolvulaceae and Solanaceae are included in the order Polymoniales

Eg

Monkey, Gorilla and Gibbon belongs to Order Primata

Binomial Nomenclature

System of providing the name with two components, i.e. generic name and specific epithet

Taxonomic Hierarchy

Species → Genus → Family → Order → Class → Phylum (for animals) /Division (for plants) →Kingdom.

\
The basic unit is species and the highest unit is kingdom.

‘Systema Naturae ‘ was written by

Carolus Linnaeus

Species

Genus

Family

A group of related genera with fewer similarities

Order

assemblage of families which exhibit a few similar characters.

Class

Related orders

Phylum

includes related classes in case of animals.

Kingdom
