Earth Life Emergence: Development of Body, Brain, Selves and Societies

Earth Life > Phenomenon > Human Societies

Drozdz, Stanislaw, et al. Complexity in Economic and Social Systems. Entropy. April, 2020. Polish Academy of Sciences theorists SD, Jaroslaw Kwapien, and Pawel Oswiecimka open a special issue for papers all about how some manner of common mathematical programs become manifestly apparent in a wide expanse of human activities.

Social phenomena like the emergence of communication and cooperation, build-up of hierarchies and organizations, opinion formation, the emergence of political systems, and the structure and dynamics of financial markets are all among the iconic examples of the
real-world complexity. Although much has already been done and much has been achieved, the complexity of the social and economic systems is still far from being properly understood. We intend this Special Issue to cover a broad variety of complexity-related topics and methods in the following fields: macroeconomics, financial markets, epidemiology, opinion formation, social systems, quantitative linguistics, and time series analysis. We especially encourage to submit manuscripts that report studies carried out with models of heterogeneous interacting agents, complex networks, multifractal analysis, non-extensive statistical mechanics, and non-extensive entropy.

St-Onge, Guiliaume, et al. School Closures, Event Cancellations and the Mesoscopic Localization of Epidemics in Networks with Higher-Order Structure. arXiv:2003.05924. We cite this current posting by Laval University, Quebec theorists including Laurent Hebert-Dufresne among a burst of papers as evidence for the inherent presence of an independent mathematical domain which then manifestly influence the dynamic spreadings.

The COVID-19 epidemic is challenging in many ways, such as failures of the surveillance system. Here, we discuss a higher-order description of epidemic dynamics on networks that provides a natural way of extending interaction models beyond simple pairwise contacts. We show that unlike the classic diffusion standard, higher-order interactions can give rise to a mesoscopic locus where the epidemic concentrates around certain substructures in the network. Unlike standard models of delocalized dynamics, epidemics in a localized phase can suddenly collapse when facing an intervention operating over structures rather than individuals. (Abstract)

Bettencourt, Luis, et al. The Interpretation of Urban Scaling Analysis in Time. Journal of the Royal Society Interface. February, 2020. In this consummate, integral year, University of Chicago, Santa Fe Institute, and Arizona State University theorists including Jose Lobo can proceed to quantify and affirm that our citified human habitations are indeed graced and braced by nested, recurrent similarities. By so doing, as many others attest, a sense of a metabolic urban organicity is akin to everywhere else is achieved. By virtue of these advances which imply a mathematic guidance, better self-organized abides can be availed.

Raimbault, Juste. Cities as They Could Be: Artificial Life and Urban Systems. arXiv:2002.12926. The University College London systems geographer (search) continues his re-imaginations of human proto-cellular habitations by way of the latest complex self-similar network dynamics. See also Hierarchy and Co-evolution Processes in Urban Systems (2001.11989), Multi-dimensional Urban Network Percolation (1903.07141) and Modeling Interactions between Transportation Networks and Territories (1902.04802).

The metaphor of cities as organisms has a long history in urban planning, and a few urban modeling approaches have explicitly been linked to Artificial Life. We propose in that paper to explore the extent of Artificial Life and Artificial Intelligence application to urban issues, by constructing and exploring a citation network of around 225,000 papers. It shows that most of the literature is indeed application of methodologies and a rather strong modularity of approaches. We finally develop ALife concepts which have a strong potential for the development of new urban theories. (Abstract)

Carmel, Yohay and Ayelet Shavit. Operationalizing Evolutionary Transitions in Individuality. Proceedings of the Royal Society B. February, 2020. Technion-Israel Institute of Technology scholars present a most comprehensive study to date of life’s ratcheted, sequential, scalar emergence of distinct “personal” organisms at each stage, which is now accepted as a valid structure. As the Abstract says, an interplay of diverse component entities as they join in bounded interactivity repeats in kind at each nested phase. With this consistency thoroughly described, Yohay Carmel notes that he is now at work on their further application as our homo sapiens transitions its global anthropic worldly consummation.

Evolutionary transitions in individuality (ETIs), such as the transition to multi-cellularity and to social colonies, have been at the centre of evolutionary research, but only few attempts were made to systematically operationalize this concept. Here we devise a set of four indicators intended to assess the change in complexity during ETIs: system size, inseparability, reproductive specialization and non-reproductive specialization. We then conduct a quantitative comparison across multiple taxa and their ETI. Our analysis reveals that inseparability has a crucial role in the process; it seems irreversible and may mark the point where group members become a new individual at a higher hierarchical level. Interestingly, we find that disparate groups demonstrate a similar pattern of progression along ETIs. (Abstract)

Pedia Sapiens: A Genesis Future on Earth and in the Heavens

Future > Old Earth

Otto, Ilona, et al. Social Tipping Dynamics for Stabilizing Earth’s Climate by 2050. Proceedings of the National Academy of Science. 117/2354, 2020. Fourteen scientists posted in Germany, Ghana, the USA, the Netherlands, Spain, Sweden, Scotland, mainly based at the Potsdam Institute for Climate Impact Research including Hans Schellnhuber put together a comprehensive array of planetary and practical energetic and metabolic aspects that need be addressed with popular synchrony over the next thirty years.

Achieving a rapid global decarbonization to stabilize the climate depends on activating contagious and fast-spreading processes of social and technological change within the next few years. Drawing on an expert workshop, and a review of literature, we propose interventions to induce positive social tipping dynamics and a real global transformation to carbon-neutral societies. These initiatives comprise removing fossil-fuel subsidies and boosting decentralized energy generation, building carbon-neutral cities, divesting from fossil fuels assets, strengthening climate education, engagement, and greenhouse gas emissions information.

Eroglu, Denz et al. Multiplex Recurrence Networks. arXiv:2003.03309. DE, Norbert Marwan and Jurgen Kurth, Potsdam Institute for Climate Impact Research and Martina Stebich, Senckenberg Research Station of Quaternary Palaeontology, Weimar describe how the latest network theories and unfolding intricacies can provide deeper insights about nature’s untangled vegetation and active weather reports. An example is a reconstruction of paleopollen from Lake Sihailongwan in northern China.

We have introduced a novel combined multiplex recurrence network (MRN) approach in order to investigate multivariate time series. The value of this approach is demonstrated on coupled map lattices and on typical palaeobotany findings. In both examples, topological changes in the MRNs allow for the detection of regime changes in their dynamics. The method advances the interpretation of pollen records by considering the vegetation as a whole and the intrinsic similarity of the different regional vegetation elements. (Abstract excerpt)

Future > New Earth > democracy

Arash, Abizadeh. Representation, Bicameralism, Political Equality, and Sortition. Perspectives on Politics. Online January, 2020. A McGill University, Iranian-Canadian political scientist offers another nuance of what “democracy” might mean. The concept is traced all the way to Athens, but none of the myriad versions since anywhere seem workable. Indeed, built-in flaws lead to insular factions and selfish behaviors which do not serve any populace. Yet, as the Abstract alludes, a truly bicameral body whence personal interests are balanced by integral responsibility ought to govern in an egalitarian way. As one reads along, the two sides of an aisle appear as a description of brain hemispheres, with individual agency leavened by contextual empathy. As this binocular decade begins, cities from Santiago and Beirut to Hong Kong and Paris and nations from Australia, Brazil, the UK and especially this USA remain beset by polar forces of every kind. How can it finally dawn that these natural halves are not warring enemies but well complement each other?

The two traditional justifications for bicameralism are that a second legislative chamber serves a legislative-review function (quality legislation) and a balancing function (checking power and protecting minorities). I furnish here a third justification for bicameralism, with one elected chamber and the second selected by lot, as an institutional compromise between contradictory imperatives facing representative democracy. Elections are a mechanism of people’s political agency and accountability, but run counter to equality and impartiality, and are insufficient for satisfactory responsiveness while sortition augurs for equality and impartiality. (Abstract excerpt)

But my underlying purpose is to advance an argument whose significance reaches beyond the Canadian context in three ways. I take the democratic tradition to be defined by two constitutive commitments: to people’s political agency and political equality. My purpose at the most general level is to show, first, that in specifically representative democracy these two commitments face and inherent trade-off: realizing the one to some degree unavoidably compromises the other. (2)

A bicameral legislature has legislators in two separate assemblies, chambers, or houses. Sortition is the selection of political officials as a random sample from a larger pool of candidates, a system intended to ensure that competent and interested parties have a chance at public office.

Future > New Earth > Viable Gaia

Yeang, Ken. Saving the Planet by Design: Renewing Our World Through Ecomimesis. London: Routledge,, 2019. The veteran Malaysian-British, Cambridge University systems architect and author offers his latest advice by way of a similar ecological concept to biomimesis so to inform and guide our respectful reconception of a truly habitable planet.

For a resilient, durable and sustainable future for human society, we need to repurpose, reinvent, redesign, remake and recover our human-made world so that our built environment is benignly and synergistically biointegrated with Nature. Implementing this vital sustainability is of most concern to architects, engineers, landscapers, town planners, policy makers, builders and beyond to all of humanity. Two key principles to by which to carry out these tasks are an “ecocentricity” guided by the science of ecology, and an “ecomimesis” to design and make the natural and built environment based on the an Earthwide “ecosystem” concept.

Future > Self-Selection

Lingam, Manasvi. Implications of Abiotic Oxygen Buildup for Earth-like Complex Life. arXiv:2002.03248. A Florida Institute of Technology astrophysicist (search) surveys the importance for a bioworld to achieve a favorable atmospheric O2 level in the low 20% range for life to be able to develop and evolve. This small window between starved and burnt up need be reached in a timely way (Lineweaver) and persist over relatively long periods. This atmospheric quality would then be a vital biosignature. See also Ward, Lewis, et al. Follow the Oxygen: Comparative Histories of Planetary Oxygenation and Opportunities for Aerobic Life by Lewis Ward, et al in Astrobiology (19/6, 2019). In regard, still another vital, finely tuned check point to successfully pass through is highlighted.

One of the chief paradoxes of molecular oxygen (O2) is that it is an essential requirement for multicellular eukaryotes on Earth while simultaneously posing a threat to their survival via the formation of reactive oxygen species. In this paper, the constraints imposed by O2 on Earth-like complex life are applied to whether worlds with abiotic O2 inventories can harbor such organisms. By consideration of the O2 sources and sinks of Earth-like planets, it is proposed that worlds with X-ray and extreme ultraviolet fluxes might not host complex lifeforms because the photolysis of water molecules may cause high O2 buildup.

Future > Self-Selection

Prantzos, Nikos. A Probabilistic Analysis of the Fermi Paradox in Terms of the Drake Formula. arXiv:2003.04802. Two decades after his Our Cosmic Future book, the Institute of Astrophysics, Paris, research director provides a new update of this equation estimate of how many Earth-like worlds might exist. It is also cast another response to Enrico’s 1950s concern that no one actually seems to be there. An underrated factor may have been the lifetime duration of a technical civilization. This would have a major winnowing effect if they could not get their common act together so as to save their home bioworld. Based on our own terminal perils, this situation could imply that a decisive planetary self-realization and selection, indeed a sustainability singularity, is a critical. imperative step. In Prantzos’ expansive view, civilizations are seen to randomly come and go, some for a short period, others may be longer. Earth is not the first, nor the last, but at the present time is alone for these reasons.

In evaluating the number of technological civilizations N in the Galaxy through the Drake formula, emphasis is mostly put on astrophysical and biotechnological factors describing the emergence of a civilization and less on its lifetime L, which is strongly related to its demise. It is argued that this factor is in fact the most important regarding the practical implications of the Drake formula, because it determines the extent of the "sphere of influence" of any technological civilization. The Fermi paradox is then studied by way of a simplified Drake version through Monte Carlo simulations of N civilizations expanding in the Galaxy during their space faring lifetime. In that frame, the probability of "direct contact" is set as the fraction of the Galactic volume occupied collectively by N civilizations. The results are used to find regions in the parameter space where the Fermi paradox holds. (Abstract excerpt)
