VI. Earth Life Emergence: Development of Body, Brain, Selves and Societies
A. A Survey of Common Principles
By a 2020 wiseworld philoSophia view, many references cited in Parts III: Organic Universe, IV: Cosmomic Code and V: A Systems Evolution describe by an array of approaches and various terms an invariant presence of self-organized, network, complementary patterns and processes everywhere. This section serves to gather more reports which attest to a natural genesis by way of an independent, mathematic, one code system composed of certain dual agency/relation, node/link, member/group complements. In this manner, the universal naturome (cosmome to geonome) double duty becomes manifestly exemplified at each and every procreative stage. From protein webs to desert biotas, human cultures, microbes to a metropolis, onto the interstellar raiment, one same triality repeats over and over. We next post, for an example, a 2019 mission statement of the Santa Fe Institute.
Center for Fractal Design. www.fractal.org. Julius Ruis, the Director of this Netherlands based Fractal Design and Consultancy, has emailed me (March 2008) his compliments and to notify about his own many-faceted website. We are pleased to list as a portal to visually appreciate a nested, creative self-similarity which enlivens every aspect of a natural genesis from cosmos to cauliflowers to civilizations. The site requires some negotiation, but is filled with treasures.
, . Fractals: Hunting the Hidden Dimension. www.pbs.org/wgbh/nova/fractals. This luminous Nova program aired on October 28, 2008 muses at its close that Galileo’s mathematical book of nature is at last legible via an intrinsic geometry not of Euclidean forms but of an infinitely variegated self-similarity. The presentation dutifully engages leading contributors over the years such as Ralph Abraham, James Brown, Ron Eglash, Brian Enquist, Ary Goldberger, Geoffrey West, and so on. But a prime distinction is an extended visit with its renowned founder Benoit Mandelbrot. As one example, a research team led by ecologist Enquist is shown measuring tree branches in a Costa Rican forest and concludes that one plant and a whole biota share a common, recurrent structure, verily that a tree recapitulates its forest. A nested natural iteration is thus revealed as creation’s mathematical basis now takes on a fractal form.
Agnati, Luigi, et al. Mosaic, Self-Similarity Logic and Biological Attraction Princples. Communicative & Integrative Biology. 2/6, 2009. With co-authors Peter Barlow, Frantisek Baluska, and Diego Guidolin, Italian, German, and British theorists contribute to the growing witness of an independent, genome-like, natural topology and its constant dynamics. The quotes seem to evince a grand genesis discovery, if we could only allow ourselves and imagine.
From a structural standpoint, living organisms are organized like a nest of Russian matryoshka dolls, in which structures are buried within one another. From a temporal point of view, this type of organisation is the result of a history comprised of a set of time backcloths which have accompanied the passage of living matter from its origins up to the present day. The aim of the present paper is to indicate a possible course of this passage through time and suggest how today’s complexity has been reached by living organisms. (552)
Ahn, Yong-Yeol, et al. Link Communities Reveal Multiscale Complexity in Networks. Nature. 466/761, 2010. Researchers from the Center for Complex Network Research, Northeastern University; Center for Cancer Systems Biology, Dana-Farber Cancer Institute, Harvard University; Institute for Quantitative Social Science, Harvard; and the College of Computer and Information Science, Northeastern, resolve a conceptual issue about how to allocate, describe, and understand such omnipresent relational form and fluidity. However then by such interdisciplinarity might it dawn that a grand genesis universe is revealed with a once and future, above and below, replication that we might avail for a better world? What time is it, whom altogether is learning, in translation are we reading a cosmic to child genetic code?
Networks have become a key approach to understanding systems of interacting objects, unifying the study of diverse phenomena including biological organisms and human society. One crucial step when studying the structure and dynamics of networks is to identify communities: groups of related nodes that correspond to functional subunits such as protein complexes or social spheres. (761) Here we reinvent communities as groups of links rather than nodes and show that this unorthodox approach successfully reconciles the antagonistic organizing principles of overlapping communities and hierarchy. In contrast to the existing literature, which has entirely focused on grouping nodes, link communities naturally incorporate overlap while revealing hierarchical organization. (761) Our results imply that link communities are fundamental building blocks that reveal overlap and hierarchical organization in networks to be two aspects of the same phenomenon. (761)
Alon, Uri. Simplicity in Biology. Nature. 446/497, 2007. Although life, from proteins to genes, bacteria and metabolic organisms, epitomizes dynamic complexity, recent studies find shared principles which engender motifs and networks that repeat at every phase. These convergent, modular patterns and processes constantly recur as they take on this universal mathematical form.
Amaral, L. and J. Ottino. Augmenting the Framework for the Study of Complex Systems. European Physics Journal B. 38/2, 2004. An introduction to a special issue on the ubiquitous presence of scale-free dynamic networks from food webs and epidemics to neural phenomena and especially the worldwide Internet. In this regard a generic definition of complex systems is attempted, see the quote below. These elemental units and interactions then self-organize into a universal, nested self-similarity.
A complex system is a system with a large number of elements, building blocks or agents, capable of interacting with each other and with their environment. The common characteristic of all complex systems is that they display organization without any external organizing being applied. The whole is much more than the sum of its parts. (148)
Amgalan, Anar, et al. Unique Scales Preserve Self-Similar Integrate-and-Fire Functionality of Neuronal Clusters. arXiv:2002.10568. SUNY Stony Brook and UM Amherst computational neuroscientists including Hava Siegelmann post a strongest statement to date of the actual presence of a “functional scale-invariance or fractality” which spans its dynamic multiplex architecture. In regard, here is another current affirmation of a microcosmic instantiation of nature’s universal genetic complexities in our very own cerebral faculty.
Identifying the brain's neuronal cluster size as nodes in a network computation is critical to both neuroscience and artificial intelligence. Experiments support many forms and sizes of neural clustering, while neural mass models (NMM) assume scale-invariant functionality. Here, we use simulations within a fMRI network to show that a brains stay structurally self-similar continuously across scales. As such, we propose a coarse-graining of network of neurons to ensemble-nodes, with multiple spikes making up its ensemble-spike, and time re-scaling factor defining its ensemble-time step. The fractal-like spatiotemporal structure and function that emerges allows strategic choices across experimental scales for computational modeling, along with regulatory constraints on developmental and/or evolutionary "growth spurts" in brain size.

Anteneodo, Celia and M. G. E. da Luz. Complex Dynamics of Life at Different Scales: From Genomic to Global Environmental Issues. Philosophical Transactions of the Royal Society A. 368/5561, 2010. Brazilian biophysicists introduce a special issue that exemplifies the scientific verification across nature’s nested realms of life’s vital, inherent, ascendant, bountiful intricacy. The issue is available online with full, free access. Typical papers of note are Rudolf, Hanel, et al, “Living on the Edge of Chaos: Minimally Nonlinear Models of Genetic Regulatory Dynamics;” Pablo Gleiser and Victor Spoormaker on “Modelling Hierarchical Structure in Function Brain Networks;” and “Complex Dynamics of Our Economic Life on Different Scales” by Tobais Preis, Daniel Reith and Eugene Stanley.
In very general terms, complexity arises from relatively simple interactions among numerous mutually interacting parts. Despite the simplicity of the governing rules, a rich collective dynamic emerges which is quite distinct from that of the individual elements. (5562)
Arnold, Carrie. Ants Swarm Like Brains Think. Nautilus. Issue 23, 2015. A report on the decade-long field and laboratory project of the Stanford University biologist Deborah Gordon to study the intelligent behavior, organization, and ecology of ant colonies in the Arizona desert. These intricate insect societies are lately seen as an archetypal example of a complex system which exhibits robust communality along with integral cognitive qualities. Recently the dynamic phenomena she found was noted by the UC Davis computational neuroscientist Mark Goldman as inherently similar to layered neural network activities. Both instances involve many, interconnected entities whether ants or neurons, from which emerges a coherent, intelligent response. Thus in 2015, still another confirmation of nature’s grand, infinitely reiterated, genetic universality is achieved.
Bagrow, James and Eric Bolit. An Information-Theoretic, All-Scales Approach to Comparing Networks. Applied Network Science. 4/45, 2019. University of Vermont complexity researchers conceive a common pictorial image as an effective way to represent nature’s ubiquitous propensity to join discrete elements or entities into viable communal assemblies. The novel approach is thus dubbed a Network Portrait.
As network studies proceed, it is more common to move beyond a single network to analyze multiple arrays. An important task then becomes network comparisons by way of a similarity or distance measure in between. Here we introduce a new measure as a Network Portrait Divergence which is mathematically principled, incorporates the topological characteristics at all structural scales, and is generally applicable to all types of networks. An important feature that enables many of its useful properties is that it is based on a graph invariant. We test our measure on both synthetic graphs and real world networks taken from protein interaction data, neuroscience, and computational social science applications. (Abstract edits)
Balasis, Georgios, et al. Universality in Solar Flare, Magnetic Storm and Earthquake Dynamics using Tsallis Statistical Mechanics. Physica A. In Press, October, 2010. Astrophysicists from Athens and Paris contribute to a rush of recognitions and explanations from experiment and theory of a constant form and flux in every stellar and geospheric corner, which surely augurs for a common mathematical origin.
The new field of complex system studies holds that the dynamics of various complex systems are founded on universal principles, which can be used to describe disparate problems. A basic reason for our interest in complexity is the striking similarity in behavior near the global instability among systems that are otherwise quite different in nature. The observed similarity suggests a common approach to the interpretation of these diverse phenomena in terms of driving physical mechanisms that have the same character.
Banavar, Jayanth, et al.
Form, Function, and Evolution of Living Organisms.
Proceedings of the National Academy of Sciences.
The international team of Banavar, Todd Cooke, Andrea Rinaldo, and Amos Maritan (search each) broach a synthesis after years of research by many scientists upon the persistent, mathematical topologies of plants and animals. From innate natural principles, a universal self-similarity is found to be expressed by flora and fauna which serves to optimize energetic efficiencies. Once again a constant pattern recurs everywhere, which quite implies an intrinsic animate source.
Despite the vast diversity of sizes and shapes of living organisms, life’s organization across scales exhibits remarkable commonalities, most notably through the approximate validity of Kleiber’s law, the power law scaling of metabolic rates with the mass of an organism. Here, we present a derivation of Kleiber’s law that is independent of the specificity of the myriads of organism species. Specifically, we account for the distinct geometries of trees and mammals as well as deviations from the pure power law behavior of Kleiber’s law, and predict the possibility of life forms with geometries intermediate between trees and mammals. We also make several predictions in excellent accord with empirical data. Our theory relates the separate evolutionary histories of plants and animals through the fundamental physics underlying their distinct overall forms and physiologies. (Abstract)
