Levels of Organization

Levels of Organization

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...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Phylogeny

Phylogeny

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Characteristics of Life

Characteristics of Life

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

The Evidence for Evolution

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

The Tree of Life - Bacteria, Archaea, Eukaryotes

The Tree of Life - Bacteria, Archaea, Eukaryotes

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...

Summary

This summary is machine-generated.

Nestedness, a pattern of subset interactions, is a common feature across diverse biological networks, from genes to ecosystems. This suggests universal organizational principles govern biological systems regardless of scale or interaction type.

Background:

Biological systems exhibit complex network structures at all organizational levels.
Recurrent patterns like modularity and nestedness are observed in biological networks.
Nestedness, a pattern where interactions of less connected elements are subsets of more connected ones, was primarily studied in ecological networks.

Purpose of the Study:

To investigate the occurrence and implications of nestedness in one-mode biological networks across diverse organizational levels.
To determine if nestedness is a pervasive feature independent of biological scale or interaction type.
To theorize on the emergent principles driving nested network assembly.

Main Methods:

Computed nestedness across six distinct levels of biological organization: gene/protein interactions, complex phenotypes, animal societies, metapopulations, food webs, and vertebrate metacommunities.
Analyzed diverse one-mode networks where elements can interact with any other element.

Main Results:

Nestedness was found to emerge independently of interaction type or biological scale.
Disparate biological systems exhibit shared nested organization features characterized by inclusive subsets of interacting elements with decreasing connectedness.
The study provides evidence for the widespread occurrence of nestedness across biological scales.

Conclusions:

Nestedness is a pervasive organizational feature in biological networks, spanning from molecular to ecological levels.
A general compromise between specificity and affinity may drive the emergence of nestedness across scales.
Findings stimulate debate on the pervasiveness of nestedness and aid research into commonalities of biological networks.
