In this paper, we develop a natural (empirical) relational theory for describing and modeling complex biological phenomena. We have as stepping stone the assertion: function implies structure. The theory is built upon a graph's theory structure in which a diffusion model of information takes place, and where dynamics can be investigated in order to generate steady quantifiers.

Complexity in complex adaptive systems refers to the potential for emergent behavior in complex and unpredictable phenomena. Examples of complex adapting systems include the economy, ecosystems, the human brain, developing embryos and ant colonies. Each is a system with a network of many agents acting in parallel.
Maintaining a constant body temperature is an ecological adaptation for remaining active over a wider range of ambient temperature. Although in principle this includes high ambient temperatures, the effect is perhaps more striking at the low ambient temperature of night-time. Thermoregulation also serves another, distinctly physiological function.
Basically, adaptation is a common process in most complex systems. First of all, we need to distinguish biological adaptation that is a special case of general adaptation that we can find in other non-biological systems. In biology, adaptation is “the dynamic evolutionary process that fits organisms to their environment, enhancing their evolutionary fitness.
Irreducible complexity (ic) is the argument that certain biological systems cannot have evolved by successive small modifications to pre-existing functional systems through natural selection, because no less complex system would function.
And these aging processes can be modified through mechanisms of adaptation (information gain). A theory of complex time, or adaptation and aging in complex systems, should include the many scales and connections among dynamical processes, and recognize that the effective age of an individual is dependent on the age of their environment, technology, and culture.
Biological systems are further complicated by the fact that the folding of polypeptides and the assembly of proteins (background: polypeptides and proteins) is mediated by a network of chaperone proteins, that act to facilitate correct, and suppress incorrect, folding, interactions, and assembly of proteins. This chaperone network helps explain the ability of cells to tolerate a range of genetic variations; they render cells more adaptive and “non-fragile”.

The baliga group develops models of biological systems, from single cells to communities of multiple organisms, that accurately predict adaptation to environmental changes.

Complex systems are found not only in the ant colonies and bee hives but also in the human-made systems like transportation networks and online communities.

Biological adaptation and ageing (b2a) lifespan is rapidly increasing by about 2 years/decade and shows no signs of slowing. Thus, the prevalence of age-ralated frailty, disability and disease is unprecedented and requires a better understanding of the processes underlying ageing to improve quality of life.
The structural organization of biological systems is one of nature’s most fascinating aspects, but its origin and functional role is not yet fully understood. For instance, basic adaptational mechanisms like genetic mutation and hebbian adaptation seem to be generic and invariant across many species and are, on their own, fairly well investigated and understood.

The origins of biological complexity have been approached from both biological and physical standpoints. Traditional biological narratives view complex features as adaptations. However, more recently, neutral scenarios for evolution of complexity have been proposed (28 ⇓ ⇓ ⇓ ⇓ –33). Under these models, complexity ensues from evolutionary accumulation of genomic features, such as duplicated genes, introns, or mobile genetic elements (mge).
