The linnaean scheme for classification of living things lumps organisms together based on presumed homologies the assumption is that the more homologies two organisms share, the closer they must be in terms of evolutionary distance.

Classification of organisms - it was a necessity for primitive cultures to know their surroundings in order for survival they had to know what was safe to eat or to use in various ways, as well as what organisms could harm them. The classification reflects the evolutionary development from primitive to advanced organisms and is also compatible with the hypothesis that eukaryotes have been evolved by the symbiotic association of two or more types of prokaryotic organisms.
Classification: the scientific method of dividing organisms into smaller and larger groups, on basis of their similarities swedish botanist carolus linnaeus is the father of systematic biology. In biology, an organism (from greek: ὀργανισμός, organismos) is any individual entity that exhibits the properties of life it is a synonym for life form organisms are classified by taxonomy into specified groups such as the multicellular animals , plants , and fungi or unicellular microorganisms such as a protists , bacteria. This phylogenetic classification system names only clades — groups of organisms that are all descended from a common ancestor as an example, we can look more closely at reptiles and birds under a system of phylogenetic classification, we could name any clade on this tree for example, the.

Classification relies on both internal and the external structures of organisms, their geographical distribution, and chemical makeup to reveal probable evolutionary relationships grouping organisms based on their evolutionary relationships makes it easier to understand biological diversity. The term species has its origins in the ancient latin language in this language, the word species means kind a more technical definition of species is a group of interbreeding organisms that do not ordinarily breed with members of other groups. Classification is important because it helps scientists to clearly identify species, study and observe them, and organize concentrated conservation efforts it also assists as a way of remembering and differentiating the types of organisms, making predictions about organisms of the same type.
