Does Biology Need an Organism Concept?

  title={Does Biology Need an Organism Concept?},
  author={John W. Pepper and Matthew D. Herron},
  journal={Biological Reviews},
Among biologists, there is no general agreement on exactly what entities qualify as ‘organisms’. Instead, there are multiple competing organism concepts and definitions. While some authors think this is a problem that should be corrected, others have suggested that biology does not actually need an organism concept. We argue that the organism concept is central to biology and should not be abandoned. Both organism concepts and operational definitions are useful. We review criteria used for… 

A quantitative definition of organismality and its application to lichen

The view that the "organism" is a functional concept, used by scientists to address particular questions concerning the future state of a biological system, rather than something wholly defined by that system is adopted.

Contextual organismality: Beyond pattern to process in the emergence of organisms

It is suggested that context dependence may be a stepping stone to the development of increased organismal unification, as the most integrated biological entities generally show little context dependence.

This paper addresses the concept of individual and its role in biological theory and practice. The ability to identify individuals, paradigmatically organisms, is central not only to address them as

The Return of the Organism as a Fundamental Explanatory Concept in Biology

Although it may seem like a truism to assert that biology is the science that studies organisms, during the second half of the twentieth century the organism category disappeared from biological

Organisms or biological individuals? Combining physiological and evolutionary individuality

It is suggested that the combination of an evolutionary and a physiological perspective will enable biologists and philosophers to supply an account of biological individuality that will be both more comprehensive and more in accordance with scientific practices.

A conceptual framework for organismal biology: linking theories, models, and data.

The theory presented here is a formal expression of nearly two centuries of conceptual advances and practice in research, which includes 10 fundamental principles that apply to all organisms, and 6 that applies to multicellular organisms only.

Toward a Conceptual Framework for Biology

The nature of theory in biology is discussed and an overarching theory is put forth, as well as new general theories for cells, organisms, and genetics, which constitute a general conceptual framework for the biological sciences.

Beyond society: the evolution of organismality

This survey suggests that many of the traits commonly used to define organisms are not essential, including physical contiguity, indivisibility, clonality or high relatedness, development from a single cell, short-term and long-term genetic cotransmission, germ–soma separation and membership in the same species.

Is Romeo dead? On the persistence of organisms

It is shown that if the authors hone in on the relevant notion of naturalness, it can be shown that organisms can (and often do) continue to instantiate the natural property being an organism after death.

Essays on Biological Individuality

This dissertation distinguishes between two categories of individuality and argues that they play different roles in theorizing about nature, including that of the evolutionary individual, understood as an entity that has the capacity to participate in processes of natural selection.



Ontological Butchery: Organism Concepts and Biological Generalizations

It is argued that the two main ways to discover useful biological generalizations about multicellular organization do not require what would have to be a stipulative sharpening of an organism concept.

Do Organisms Exist

It is argued that in some respects organisms are not distinctive and in other respects they are, and biologists need not worry for the autonomy of their subject.

Organisms and their place in biology

The tension between those hierarchical schemes proposed to account for life as a global phenomenon and those approaches that take organisms as the central target of (theoretical) biology are released, suggesting a possible middle-ground solution open for further research.

Organism and Character Decomposition: Steps towards an Integrative Theory of Biology

This paper argues that an operational organism concept can help to overcome the structural deficiency of mathematical models in biology and demonstrates how a decomposition of an organism into independent characters in the context of a specific biological process--such as adaptation by means of natural selection--depends on the dynamical properties and invariance conditions of the equations that describe this process.

Biology's “Phoenix”: Historical Perspectives on the Importance of the Organism

Several contemporary biologists have critically evaluated this situation and have attempted to formulate biological methods that would once again consider the entire organism as the central focus for biological investigation.

On some theoretical grounds for an organism-centered biology: Property emergence, supervenience, and downward causation

It is maintained that a philosophical alternative worthy of investigation is that of a combination of supervenience and property emergence in the formulation of such a stance, and a new definition of an emergent property is discussed.

The concept of the organism in physiology

Focus on the function of fully developed or adult organisms has been accompanied by a relative neglect of developmental processes, and incorporation of evolutionary, ecological, and developmental perspectives into the study of organisms might help to unite physiology more closely with the other biological sciences and lead to a richer and fuller understanding of organisms.
