Significance of Classification Helps to systematically organise the diversity of organisms. Helps to determine the relation between organisms Helps to trace the possible origins of organisms Helps to identify the great variety of living things
What is Taxonomic order? One common way of classifying living things is based in the Linnaeus System of classification which puts organisms into Taxonomic Groups that indicate their natural relationships.
Eight Taxonomic Groups Living things are placed into the eight taxonomic groups: Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species based on certain similarities
Diversity of Humans Humans are a species of Homo Sapiens and are divided into the following:
DOMAIN A domain is the top level grouping of organism. Organisms are classified according to cellular characteristics. Each domain consists of a number of kingdoms like plant and animal kingdom.
KINGDOM A kingdom is the second level of grouping. A group of similar kingdom forms a domain. A kingdom contains one or more phylum.
Phylum A phylum (division) is a taxonomic group of related or similar organisms. Each phylum consists of a number of classes.
Class A class contains one or more orders. A group of similar classes forms a Division.
Order An order contains one or more families like carnivore, omnivore etc. A group of similar orders forms a class.
Family A family contains one or more genera (plural of genus). A group of similar families forms an order. A family may be divided in subfamilies.
Genus The genus is a grouping of similar and closely related species. The scientific name for man is ‘Homo sapiens’ which means ‘wise man. Modern man belongs to genus Homo. The first part reflects the genus. This system is used to name living thing.
Species The two part naming system (mentioned in above section) is used to name living thing. The second part of the name sapiens identifies the species.
