The science of classifying living things is called taxonomy. Linnaeus introduced the classification system that forms the basis of modern classification. Taxa in the Linnaean system include the kingdom, phylum, class, order, family, genus, and species. Linnaeus also developed binomial nomenclature for naming species.

Protochordata are divided into three most important sub-categories based on the kind of notochord they possess, namely Hemichordata, Urochordata and Cephalochordata.
What is the basis of classifying mammals?
Traditional classifications of mammals are based on similarities in structure and function. Increasingly, mammals are being classified on the basis of molecular similarities. DNAanalyses has recently shown that the traditional orders include mammals that may not be closely related.
What are the basis of classification of animal kingdom explain with suitable examples and diagram?
The animal kingdom has been broadly classified into two, based on the presence or absence of notochord- Non-Chordata and Chordata. Chordates possess notochord while non-chordates lack it. Animals belonging to the Phylum Porifera to Phylum Echinoderms are non-chordates.

What is the basis of classification of diversity in living organisms?
The classification Whittaker proposed has five kingdoms: Monera, Protista, Fungi, Plantae and Animalia, and is widely used. These groups are formed on the basis of their cell structure, mode and source of nutrition and body organisation.

What is the main basis of classification in five kingdom system?
Four major criteria on which the five-kingdom classification was based are: Prokaryotic and eukaryotic nature. Unicellular and multicellularity. Mode of nutrition like holophytic, absorptive and ingestive.
What is the basis of natural system of classification?
The natural system of classification is a type of classification in which properties such as morphology, cytology(cell structure), phytochemistry(chemicals found in plants), embryology, and anatomy are applied to find similarities and affinities among organisms.
Who laid the real basis for modern classification and nomenclature?
