Breaking down levels of biological organization
Theoretical Biology Forum
|March 20, 2014
Summary
Cancer biology offers insights into biological organization, revealing a dynamic, multilevel system. Understanding cancer requires a nuanced view of organization and causality, moving beyond simple part-whole relationships.
Area of Science:
- Systems biology
- Philosophy of science
- Cancer biology
Background:
- Biological organization is complex, involving hierarchical structures and functions.
- Cancer disrupts normal biological organization at multiple levels (tissues, cells, genes).
- Existing models often rely on a simplistic part-whole perspective for biological systems.
Purpose of the Study:
- To explore the multilevel phenomenon of cancer biology.
- To propose a non-univocal concept of organization and causality in biological systems.
- To reframe the understanding of hierarchical control in biological behaviors.
Main Methods:
- Analysis of cancer biology features.
- Examination of interpretative models converging on operational accounts of levels.
- Conceptual shift from part-whole to multi-unity perspectives.
Main Results:
- Cancer's multilevel nature provides insights into biological system organization.
- A non-univocal notion of organization and dual dimensions of part-whole dependence are necessary.
- Dynamic control of organizational levels is crucial for understanding biological systems.
Conclusions:
- Understanding biological systems, particularly cancer, necessitates a dynamic and multilevel approach.
- A multi-unity perspective better explains the hierarchical control of biological behaviors than traditional part-whole views.
- Rethinking organization and causality is key to advancing systems biology and cancer research.

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:
The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules...

01:18Structural Organization of the Human Body: An Overview
29.2K
It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...

01:35Trophic Levels
28.7K
All organisms in an ecosystem occupy a trophic level in the food chain. The lowest level consists of primary producers, which synthesize their food from either solar or chemical energy. Each subsequent level obtains energy from the levels below. Detritivores can occupy any of the levels above primary producers.

01:24Microbial Classification System
1.8K
Classification is the process of organizing organisms into hierarchically inclusive groups based on their phenotypic similarities or evolutionary relationships. A species comprises one or more strains, and closely related species are grouped into genera. Genera are further classified into families, families into orders, orders into classes, and so forth, up to the domain level, which is the broadest taxonomic rank derived from a combination of phenotypic and genotypic data.The nomenclature of...

02:40The Tree of Life - Bacteria, Archaea, Eukaryotes
36.5K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

01:31Taxonomy
69.3K
Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.
