  2. Order (biology) - Wikipedia

    en.wikipedia.org/wiki/Order_(biology)

    Order (Latin: ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class . In biological classification , the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes .

  3. Taxonomy (biology) - Wikipedia

    en.wikipedia.org/wiki/Taxonomy_(biology)

    He not only introduced the standard of class, order, genus, and species, but also made it possible to identify plants and animals from his book, by using the smaller parts of the flower (known as the Linnaean system). [51] Plant and animal taxonomists regard Linnaeus' work as the "starting point" for valid names (at 1753 and 1758 respectively ...

  4. Linnaean taxonomy - Wikipedia

    en.wikipedia.org/wiki/Linnaean_taxonomy

    The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order. A term for rank-based classification of organisms, in ...

  5. Biological organisation - Wikipedia

    en.wikipedia.org/wiki/Biological_organisation

    Biological organisation is the organisation of complex biological structures and systems that define life using a reductionistic approach. [1] The traditional hierarchy, as detailed below, extends from atoms to biospheres. The higher levels of this scheme are often referred to as an ecological organisation concept, or as the field, hierarchical ...

  6. Spontaneous order - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_order

    Spontaneous order, also named self-organization in the hard sciences, is the spontaneous emergence of order out of seeming chaos. The term "self-organization" is more often used for physical changes and biological processes, while "spontaneous order" is typically used to describe the emergence of various kinds of social orders in human social networks from the behavior of a combination of self ...

  7. Biological system - Wikipedia

    en.wikipedia.org/wiki/Biological_system

    A biological system is a complex network which connects several biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. [1] Examples of biological systems at the macro scale are populations of organisms.

  8. Living systems - Wikipedia

    en.wikipedia.org/wiki/Living_systems

    Harris Bernstein and colleagues argued in 1983 that the evolution of order in living systems and certain physical systems obeys a common fundamental principle termed the Darwinian dynamic. This was formulated by first considering how macroscopic order is generated in a simple non-biological system far from thermodynamic equilibrium, and then ...

  9. Organ (biology) - Wikipedia

    en.wikipedia.org/wiki/Organ_(biology)

    Two or more organs working together in the execution of a specific body function form an organ system, also called a biological system or body system. An organ's tissues can be broadly categorized as parenchyma , the functional tissue, and stroma , the structural tissue with supportive, connective, or ancillary functions.
