Taxonomic Hierarchy of Living Organisms: Unit of Classification:
A hierarchy is formed in the classification that starts with Kingdom Animalia or Kingdom Plantae; further groups and subgroups are formed depending upon basic similarities and differences. This is called the ‘hierarchy of classification.’
Hierarchy | Mango | Human |
---|---|---|
Kingdom | Plantae | Animalia |
Phylum | Anthophyta | Chordata |
Class | Dicotyledonae | Mammalia |
Order | Sapindales | Primates |
Family | Anacardiaceae | Hominidae |
Genus | Mangifera | Homo |
Species | indica | sapiens |
Level | Description | Example |
---|---|---|
Genus | A group of similar species. Species within the same genus share characteristics but cannot interbreed. | House crow (Corvus splendens) and hill crow (Corvus macrorhynchos) belong to the same genus, Corvus. |
Family | A group of related genera that share common characteristics. | Lion (Panthera leo) and tiger (Panthera tigris) belong to the genus Panthera, and together with the domestic cat (Pelis), they form the cat family (Felidae). |
Order | A group of related families. | The cat family (Felidae) and dog family (Canidae) form the order Carnivora. |
Class | A group of related orders. | The order of dogs, cats, bats, whales, monkeys, and humans forms the class Mammalia. |
Phylum | A group of related classes. | The classes of mammals, birds, reptiles, frogs, and fishes make up the phylum Chordata (animals with a notochord or backbone). |
Kingdom | The largest division in the classification of living beings, consisting of related phyla. | All animals (including mammals, birds, reptiles, etc.) belong to the kingdom Animalia. |
