In recent years, ideas such as “life is information processing” or “information holds the key to understanding life” have become more common. However, how can information, or more formally Information Theory, increase our understanding of life, or life-like systems?
Information Theory not only has a profound mathematical basis, but also typically provides an intuitive understanding of processes, such as learning, behavior and evolution terms of information processing.
In this special issue, we are interested in both:
the information-theoretic formalization and quantification of different aspects of life, such as driving forces of learning and behavior generation, information flows between neurons, swarm members and social agents, and information theoretic aspects of evolution and adaptation, and
the simulation and creation of life-like systems with previously identified principles and incentives.
Topics with relation to artificial and natural systems:
information theoretic intrinsic motivations
information theoretic quantification of behavior
information theoretic guidance of artificial evolution
information theoretic guidance of self-organization
information theoretic driving forces behind learning
information theoretic driving forces behind behavior
information theory in swarms
information theory in social behavior
information theory in evolution
information theory in the brain
information theory in system-environment distinction
information theory in the perception action loop
information theoretic definitions of life

Information theory and entropy methods are becoming powerful tools in biology, from the level of individual cells, to whole ecosystems, to experimental design, model-building, and the measurement of biodiversity. The aim of this investigative workshop is to synthesize different ways of applying these concepts to help systematize and unify work in biological systems. Early attempts at “grand syntheses” often misfired, but applications of information theory and entropy to specific highly focused topics in biology have been increasingly successful. In ecology, entropy maximization methods have proven successful in predicting the distribution and abundance of species. Entropy is also widely used as a measure of biodiversity. Work on the role of information in game theory has shed new light on evolution. As a population evolves, it can be seen as gaining information about its environment. The principle of maximum entropy production has emerged as a fascinating yet controversial approach to predicting the behavior of biological systems, from individual organisms to whole ecosystems. This investigative workshop will bring together top researchers from these diverse fields to share insights and methods and address some long-standing conceptual problems.
So, here are the goals of our workshop:
To study the validity of the principle of Maximum Entropy Production (MEP), which states that biological systems – and indeed all open, non-equilibrium systems – act to produce entropy at the maximum rate.
To familiarize all the participants with applications to ecology of the MaxEnt method: choosing the probabilistic hypothesis with the highest entropy subject to the constraints of our data. We will compare MaxEnt with competing approaches and examine whether MaxEnt provides a sufficient justification for the principle of MEP.
To clarify relations between known characterizations of entropy, the use of entropy as a measure of biodiversity, and the use of MaxEnt methods in ecology.
To develop the concept of evolutionary games as “learning” processes in which information is gained over time.
To study the interplay between information theory and the thermodynamics of individual cells and organelles.
On Friday, I had an excellent and stimulating conversation with Arieh Ben-Naim about his recent writing and work, and he mentioned in passing that he had been invited to a conference relating to entropy and biology in Vienna. A quick websearch found it quickly, and not having heard about it myself yet, I thought I’d pass it along to others who are regular readers and interested in the area.
The workshop on “Entropy in Biomolecular Systems” is being hosted by the Centre Européen de Calcul Atomique et Moléculaire (CECAM)
I’ll note that the registration deadline is on April 21 with a payment deadline of April 30, so check in quickly if you haven’t already.
The summary from the workshop website states:
This workshop brings together the world’s experts to address the challenges of determining the entropy of biomolecular systems, either by experiment or computer simulation. Entropy is one the main driving forces for any biological process such as binding, folding, partitioning and reacting. Our deficient understandng of entropy, however, means that such important processes remain controversial and only partially understood. Contributions of water, ions, cofactors, and biomolecular flexibility are actively examined but yet to be resolved. The state-of-the-art of each entropy method will be presented and explained, highlighting its capabilities and deficiencies. This will be followed by intensive discussion on the main areas that need improving, leading suitable actions and collaborations to address the main biological and industrial questions.
Further details on the workshop can be found on the CECAM website.
A few weeks ago I had communicated a bit with paleoanthropologist John Hawks. I wanted to take a moment to highlight the fact that he maintains an excellent blog primarily concerning his areas of research which include anthropology, genetics and evolution. Even more specifically, he is one of the few people in these areas with at least a passing interest in the topic of information theory as it relates to his work. I recommend everyone take a look at his information theory specific posts.
I’ve previously written a brief review of John Hawks’ (in collaboration with Anthony Martin) “Major Transitions in Evolution” course from The Learning Company as part of their Great Courses series of lectures. Given my interest in the MOOC revolution in higher education, I’ll also mention that Dr. Hawks has recently begun a free Coursera class entitled “Human Evolution: Past and Future“. I’m sure his current course focuses more on the area of human evolution compared with the prior course which only dedicated a short segment on this time period. Given Hawks’ excellent prior teaching work, I’m sure this will be of general interest to readers interested in information theory as it relates to evolution, biology, and big history.
I’d love to hear from others in the area of anthropology who are interested in information theoretical applications.
This year is the progenitor of what appears to be the biggest renaissance for the application of information theory to the area of biology since Hubert Yockey, Henry Quastler, and Robert L. Platzman’s “Symposium on Information Theory in Biology at Gatlinburg, Tennessee” in 1956. (I might argue it’s possibly even bigger than Claude Shannon’s Ph.D. thesis.) It certainly portends to create a movement that will rapidly build upon and far surpass Norbert Weiner’s concept of Cybernetics and Ludwig von Bertalanffy’s concept of General Systems Theory.
The BIRS workshop will be a bit more general in its approach while the NIMBioS workshop has a slightly tighter view specifically on maximum entropy as applied to biology.
Even more telling (and perhaps most promising) about the two workshops is the very heavy mathematical bent both intend to make their focus. I have a theory that the bounds of science are held below the high water level of mathematics (aka are “bounded by” in mathematics-speak), so there is nothing more exciting than to see groups attempting to push the mathematics and its application further. It was both the lack of mathematical rigor and the general youth of biology (and specifically genetics and microbiology) in the 1950’s which heavily hampered the early growth of cybernetics as a movement. Fortunately this is no longer the case on either count. Now we just need more researchers who are more readily conversant in the two realms simultaneously.
Though there is a paucity of equations, particularly on the information theoretic side, Loewenstein does a fantastic job of discussing the theory and philosophy of what is going on in the overlapping fields of information theory and microbiology. (I will note that it is commonly held wisdom within publishing, particularly for books for the broader public, that the number of equations in a text is inversely proportional to the number of sales and I’m sure this is the reason for the lack of mathematical substantiation which he could easily have supplied.)
This is a much more specific and therefore much better – in my mind – book than John Avery’s Information Theory and Evolution which covers some similar ground. Loewenstein has a much better and more specific grasp of the material in my opinion. Those who feel overwhelmed by Loewenstein may prefer to take a step back to Avery’s more facile presentation.
Loewenstein has a deft ability to describe what is going on and give both an up-close view with many examples as well as a spectacular view of the broader picture – something which is often missing in general science books of this sort. Readers with no mathematical or microbiology background can benefit from it as much as those with more experience.
One thing which sets it apart from much of its competition, even in the broader general science area of non-fiction, is that the author has a quirky but adept ability to add some flowery language and analogy to clarify his points. Though many will find this off-putting, it really does add some additional flavor to what might be dry and dull explication to many. His range of background knowledge, philosophy and vocabulary are second only (and possibly even on par or exceeding in some cases) that of Simon Winchester.
I’d highly recommend this book to people prior to their academic studies of biochemistry or molecular cell biology or to budding biomedical engineers prior to their junior year of study. I truly wish I had read this in 1994 myself, but alas it didn’t exist until a few years after. I lament that I hadn’t picked it up and been able to read it thoroughly until now.
For my part, his drastically differing viewpoint of the way in which biology should be viewed moving forward, is spot on. I am firmly a member of this new “school”. His final chapter on this concept is truly illuminating from a philosophical and theoretical view and I encourage people to read it first instead of last.
I’ll also note briefly that I’ve seen some reviews of this book which make mention of creationism or intelligent design and whether or not proponents of those philosophies feel that Loewenstein’s work here supports them or not, particularly since Loewenstein appeared on a panel with Dembski once. I will state for those who take a purely scientific viewpoint of things, that this book is written in full support of evolution and microbiology and doesn’t use the concept of “information” to muddy the waters the way many ID arguments are typically made.

David Christian, a trained historian, is one of the leading proponents of the relatively new concept of Big History, which I view as a sea-change in the way humans will begin to view not only the world but our place in it and what we might expect to come in the future. His work presents a truly monumental and profound thesis and a drastically new framework for where humankind fits into the universe. Of the broad variety of works I’ve read in the past several decades, it is simply one of the most interesting and cohesive theses I’ve come across, and I highly and unreservedly recommend it to everyone I know. I’d put it on par or above works like Jared Diamond’s Guns, Germs, and Steel and Matt Ridley’s The Rational Optimistamong others for its broad impact on how I now view the world. For scientists and researchers it has the potential to be the philosophical equivalent of The Bible and in fact, like many religious texts, it is in effect a modern day “creation myth,” albeit one with a scientific underpinning.
Christian’s work was initially brought to my attention by an article in the Chronicle of Higher Education by Jeffrey R. Young in which he mentioned that Bill Gates was a big fan of Christian’s work and had recommended it himself at a TED conference. (Gates is now also a financial supporter of Christian’s Big History Project.) I myself was aware of the Learning Company’s generally excellent coursework offerings and within a few weeks got an audio copy of the course of forty-eight lectures to listen to on my daily commute.
I’ve now devoured both his rather large text on the subject as well as a lecture series he created for a course on the subject. Below are brief reviews of the two works.The magnum written opus Maps of Time: An Introduction to Big History is an interesting change of reference from a historical perspective combining the disciplines of physics, cosmology, astronomy, geology, chemistry, microbiology, evolutionary theory, archaeology, politics, religion, economics, sociology, and history into one big area of contiguous study based upon much larger timescales than those traditionally taken in the study of historical time periods. Though it takes pieces from many disciplines, it provides for an interesting, fresh, and much needed perspective on who humans are and their place in not only the world, but the entire universe.
By looking at history from a much broader viewpoint (billions of years versus the more common decades or even just a few centuries) one comes away with a drastically different perspective on the universe and life.
I’d highly recommend this to any general reader as early as they can find time to read through it, particularly because it provides such an excellent base for a variety of disciplines thereby better framing their future studies. I wish I had been able to read this book in the ninth or tenth grade or certainly at the latest by my freshman year in college – alas the general conception of the topic itself didn’t exist until after I had graduated from university.
Although I have significant backgrounds in most, if not all, of the disciplines which comprise the tapestry of big history, the background included in the book is more than adequate to give the general reader the requisite introductions to these subjects to make big history a coherent subject on its own.
This could be an extremely fundamental and life-changing book for common summer reading programs of incoming college freshman. If I could, I would make it required reading for all students at the high school level. Fortunately Bill Gates and others are helping to fund David Christian’s work to help introduce it more broadly at the high school and other educational levels.
Within David Christian’s opus, there is also a collection of audio lectures produced by The Learning Company as part of their Great Courses series which I listened to as well. The collection of forty-eight lectures is entitled Big History: The Big Bang, Life on Earth, and the Rise of Humanity (Great Courses, Course No. 8050). It provides a much quicker philosophical overview of the subject and doesn’t delve as deeply into the individual disciplines as the text does, but still provides a very cohesive presentation of the overall thesis. In fact, for me, the introduction to the topic was much better in these audio lectures than it was in the written book. Christian’s lecture style is fantastic and even better than his already excellent writing style.
In the audio lectures Christian highlights eight major thresholds which he uses as a framework by which to view the 13.4 billion years of history which the Universe has presently traversed. Then within those he uses the conceptualization of disparities in power/energy as the major driving forces/factors in history in a unique and enlightening way which provides a wealth of perspective on almost every topic (scientific or historical) one can consider. This allows one to see parallels and connections between seemingly disparate topics like the creations of stars and the first building of cities or how the big bang is similar to the invention of agriculture.
I can easily say that David Christian’s works on big history are some of the most influential works I’ve ever come across – and having experienced them, I can never see our universe in the same naive way again.
For those interested in taking a short and immediate look at Christian’s work, I can recommend his Ted Talk “The History of Our World in 18 Minutes” which only begins to scratch the surface of his much deeper and profound thesis: [ted id=1118]
Given how profound the topic of big history is, I’m sure I’ll be writing about and referring to it often. Posts in relation to it can be found here with the tag: “big history“.
In Big History and the Future of Humanity, Fred Spier has built on an earlier work of his and on the work of Eric Chaisson to produce what is currently by far the most sophisticated attempt to construct a thematic scaffolding for big history. He carefully links the idea of increasing complexity with the associated themes of energy flows and the idea of goldilocks conditions—the notion that complexity can increase only under very special conditions and within quite exacting “boundary conditions.” Here are broad theoretical ideas that can help give greater depth and coherence to the story told within big history.

But precisely how chemical evolution generated the first living organisms remains unclear. To understand these difficulties, we must break the problem into several levels. First, we need to explain how the basic raw materials of life were created: the chemical level. Second, we need to explain how these simple organic materials were assembled into more complex structures. Finally, we need to explain the origins of the precise mechanisms of reproduction encoded in the DNA that is present in all living organisms today. At present, we have reasonably good answers to the first question; we have plausible answers to the second question; and we are still puzzled by the third question.

Humans do not have the 60,000 to 80,000 genes we once believed were necessary to construct us but half that number, about 30,000. Roundworms have two-thirds as many genes as us (ca. 19,000), and fruit flies just under half (ca. 13,000); even Escherichia coli, a bacterium that inhabits our gut, may have as many as 4,000 genes. So, though constructing large organisms is tougher than constructing small organisms, the difference is not as great as we once imagined.

In the middle of the nineteenth century, the German biologist Ernst Haeckel suggested that all single-celled organisms be classified within a separate kingdom of Protista. Then, in the 1930s, biologists realized that there was a fundamental difference between cells with nuclei and those without. As a result, they began to divide all organisms into two distinct kingdoms, the Prokaryota (organisms whose cells had no nuclei) and the Eukaroyta (organisms whose cells had nuclei). In some systems, the Eukaryota also include all multicellular organisms. In the second half of the twentieth century, powerful arguments emerged for the creation of separate kingdoms for fungi and for viruses (which are so simplified that they cannot even reproduce without hijacking the metabolic systems of other organisms). In the 1990s, Carl Woese proposed a new large classification to distinguish between the archaea and other forms of bacteria. Like all prokaryotes, archaea do not have nuclei; but unlike other prokaryotes they take in energy neither from sunlight nor from oxygen but from other chemicals.

We have seen that the emergence of new forms of complexity always involves the creation of large structures within which previously independent entities are locked into new forms of interdependence and new rules of cooperation.7 Following this hint, we should expect to find that the transition to human history is primarily marked not by a change in the nature of humans as individuals but rather by a change in the way individuals relate to each other.

Australian archaeologist Rhys Jones referred to such techniques as “fire stick farming.”39 Fire stick “farmers” deliberately set fire to bushland in regular cycles. In part, their aim was to prevent buildups of combustible material that could lead to hotter and more dangerous fires. But by clearing away underbrush, fire stick farming also encouraged the growth of new plants that, in turn, attracted browsers that could be hunted. Recent research suggests that such techniques may have been used as early as 45,000 years ago.40

In fact, most of human history (chronologically speaking) has taken place in communities quite innocent of state power. Even in the villages of the early agrarian era, for most people, most of the time, the important relationships were personal, local, and fairly egalitarian. Most households were self-sufficient, and people dealt with each other as people rather than as the representatives of institutions.

But exploitation, like symbiosis, is never simple or unambiguous. Like predation in the nonhuman world, it can take more or less brutal forms. Lynn Margulis and Dorion Sagan observe, “In the long run, the most vicious predators, like the most dread disease-causing microbes, bring about their own ruin by killing their victims. Restrained predation—the attack that doesn’t quite kill or does kill only slowly—is a recurring theme in evolution.”

But most were used as sources of stored energy for their owners: where human labor power was as important a source of energy as oil is today, controlling energy meant controlling people. To make slaves more amenable to control, they were often separated at birth from their families. And, like domestic animals, many were deliberately kept in a state of infantile dependence that inflicted a sort of psychic amputation on them—they remained like children, and their helplessness made them easier to control. Both animal and human slaves could be controlled best if kept economically and psychically dependent on their owners.

Outside the cities, they usually had little authority over the more localized forms of violence used to collect taxes, prosecute offenders or deal with banditry, or right local injustices. These powers were exercised by local elites or kinship groups.

World historians have become increasingly sensitive to the importance of large systems of interaction, and have often analyzed them using the notion of world-systems. Immanuel Wallerstein, the originator of such theories, argued that particularly in the modern era, it was necessary to analyze not just particular nations or civilizations, but rather the larger networks of power and commerce in which they were entangled, because these networks explained features that could not be explained solely from the internal history of particular regions. Wallerstein called these networks “world-systems,” even though they did not literally embrace the entire world, on the grounds that in many regards they functioned as separate worlds.

Centers of gravity gave structure and shape to large networks of exchange, while hub regions were more lightweight and were more easily transformed by the exchanges that swept through them. So it was often in hub regions that significant innovations first became important because here was where they could have the greatest impact, while the mass and momentum of centers of gravity ensured that those regions normally changed more slowly.

One reason for their immense influence was the overwhelming importance of the agrarian sector. Where most forms of production relied on organic materials and energy sources, agricultural output set limits to the production not just of foodstuffs but also of clothing, housing, energy, productive implements, and even parchment and paper.33 Because agriculture was the main motor of economic growth in the agrarian era, rates of innovation in agriculture dominated medium-term economic, political, and even cultural cycles.

Though tributary states normally tolerated and sometimes encouraged commerce, their predatory methods and willingness to resort to force were ever-present threats to the freedoms needed for trade to flourish. There was therefore a fundamental long-term conflict between the methods of tribute takers and those of merchants; and as long as tributary elites dominated political systems, this conflict limited the productivity-raising potential of commercial activity.

Part V: The Modern Era: One World
Scythians north of the Black Sea more than 2,000 years ago:
But though they are on the whole less violent, personal relations in modern urban communities also lack the intimacy and continuity of those in most traditional societies. Increasingly, they are casual, anonymous, and fleeting. These changes may help explain the loss of a clear sense of values and meaning in modern lives, a subtle and disorienting alteration in the quality of modern life that the French sociologist Émile Durkheim referred to in the late nineteenth century as “anomie.”
The German sociologist Norbert Elias has argued that these changes have reached deep within our psyches, as modern forms of work and time discipline, enforced through the market, have shaped behavior in interpersonal relations, table manners, and attitudes toward sexuality. He has shown how the “emotional economy” typical in the modern world arises out of a relaxation of external restraints combined with an intensification of internal restraints: “The compulsions arising directly from the threat of weapons and physical force gradually diminish, and . . . those forms of dependency which lead to the regulation of the affects [feelings or emotions] in the form of self-control, gradually increase.”
As Daniel Headrick writes: “Knowledge is both cause and effect of economic growth, and the information industry has been the primary cause of the acceleration of technological change in the past 200 years.”
the very nature of most premodern states suggests that as a general rule, in agrarian civilizations tribute-taking generated more wealth and certainly more power than commercial exchanges. This differential helps us understand what might at first appear puzzling: though commercial networks are as old as agrarian civilization, their impact on rates of innovation has been limited until the past two or three centuries. Why, then, did commercial exchanges suddenly become so much more significant in the modern era? Did they reach some critical threshold?
And what then is the next threshold? For think of what the Internet is doing to the entertainment industry and their reticence to go along with it.
Speaking generally, it is the steepness of this gradient of wealth that accounts for capitalism’s remarkable dynamism, just as the large temperature gradient between the Sun and the space surrounding it drives complex processes on Earth.
is the steepness of the gradient that drives wealth so efficiently through capitalist societies and that helps explain why, paradoxically, modern states have to be so much larger and more complex than the states of the tributary world.
So the onus is on the workers to ensure that their labor is productive enough to find a buyer. In this way, the economic lash can stimulate genuine, even creative, self-discipline, whereas the overseer’s whip can generate no more than grudging conformity.
Well-to-do merchants accumulate goods and redouble their profits, while the less well-to-do sit in their shops and sell. They control the markets and daily enjoy their ease in the cities. They take advantage of the pressing needs of the government to sell at twice the normal price. Their sons do not plough or hoe. Their daughters do not raise silkworms or weave. They have fancy clothing and stuff themselves on millet and meat. They earn fortunes while suffering none of the hardships which the farmers suffer. Their wealth enables them to hobnob with princes and marquises, and to dispose of greater power than the officials.29
This quote about 2nd century BCE China sounds a lot like modern day China.
this process was completed by 1279 after the conquest of South China by the Mongols under Kublai Khan. After reunification, two of the three conditions encouraging states to support commercialization (small size and intense rivalries) vanished, and the third (easy access to rich trading systems) lasted only slightly longer.
wealth. The mercantilist policies of European states in the seventeenth century—such as the Navigation Acts of the English commonwealth, which protected British commerce within British colonies—are good examples of new government attitudes toward commerce and the actions that these changes encouraged. Also illustrating this trend is the proliferation throughout Europe of patent laws, which were pioneered in Venice in the fifteenth century. Governments also began to promote innovation through the founding of scientific societies or the offering of prizes.
Over time, commercialization transformed traditional tributary elites. Such transformation was most likely to occur when demands on elite incomes rose sharply in environments where commercial revenues were available for the taking. The English wool trade offers a classic example, for it tempted landowners to clear the land of tenants and replace them with sheep, particularly in the sixteenth century, when new land became available as a result of the dissolution of the monasteries.

On Earth, the temperature differential between our sun and surrounding space provides the free energy needed to create most forms of complexity, including ourselves; energies created early in the history of our solar system drive the internal heat battery of Earth, which drives plate tectonics. These differentials enable energy to flow, and energy flows make patterns possible. And given enough time, the mere possibility of pattern makes it likely that patterns of many different kinds will eventually appear.
Highlight (yellow) – Location 11024

Roughly speaking, the more complex a phenomenon is, the denser the energy flows it must juggle and the more likely it is to break down.

Perhaps even a slight increase in complexity can sharply increase their fragility and, therefore, their scarcity.
