In the target article “How molecules became signs” I offer a molecular “thought experiment” that provides a paradigm for resolving the major incompatibilities between biosemiotic and natural science accounts of living processes. To resolve these apparent incompatibilities I outline a plausible empirically testable model system that exemplifies the emergence of chemical processes exhibiting semiotic causal properties from basic nonliving chemical processes. This model system is described as an autogenic virus because of its virus-like form, but its nonparasitic self-repair and reproductive (...) dynamics. The 16 commentaries responding to this proposal recognize its material plausibility but are divided on its value in resolving this basic biosemiotic challenge. In response, I have addressed some of the most serious criticisms raised and have attempted to diagnose the major sources of incompatible assumptions that distinguish the autogenic paradigm from other major paradigms. In particular, I focus on four main issues: the significance of the shift from a cellular to a viral perspective, the relevance of intrinsic versus extrinsic initiation and channeling of interpretive work, the insufficiency of molecular replication as a basis for grounding biological semiosis, and a (universal?) three step scaffolding logic that enables referential displacement of sign vehicle properties without loss of referential continuity (as exemplified by DNA-protein relations). Although I can’t conclude that this is the only way that biosemiotic properties can emerge from physical-chemical relations that otherwise lack these properties, I contend that this approach offers a biologically plausible demonstration that it is possible.

The present article will introduce a proposition of semiotic methodology that can be used to diagnose cohabitation issues in cities between human inhabitants and non-human liminals. This methodology is built on a few sets of data that should be easy to obtain in any important city, and can therefore be utilised in a variety of situations. The different sets of data allow us to map the cohabitation semiosphere (following Hoffmeyer’s meaning of the term) of the situation along three axes: the (...) materiality of the situation, the symbolic significance of the relationship, and the emotional significance of the interaction. These three aspects allow us to see gaps, paradoxes and points of consistency, enabling complex and multi-level understanding of the situation. (shrink)

In a development of the ecosemiotic vivo-scape concept, a ‘safety eco-field’ is proposed as a model of a species response to the safety of its environment. The safety eco-field is based on the ecosemiotic approach which considers environmental safety as a resource sought and chosen by individuals to counter predatory pressure. To test the relative safety of different locations within a landscape, 66 bird feeders (BF) were deployed in a regular 15 × 15 m grid in a rural area, surrounded (...) by shrubs, small trees, hedgerows, and buildings. On each of 48 days in November 2021 and February and March 2022, dried mealworms were placed on each BF and counts of larvae at each BF were made at noon and dusk. The European robin (Erithacus rubecula) and the great tit (Parus major) were the most regular visitors to the BFs. Land cover at each BF was recorded. Bird behaviour at the BFs was noted from direct video recordings of the birds at nine selected BFs, totalling 32 daily sessions in March. The different behaviours of the European robin and the great tit were observable. The safety eco-field changed according to the month and the time of day. The distance of the BF from the woodland edges seemed to be important only in the morning. In the afternoon, BFs that were more distant from the woodland edges received the highest number of visits. Weather conditions were found to influence the number of mealworms removed, but this requires further investigation. A significant relationship between land cover and the number of mealworm larvae removed from the BFs was observed. Within the grid of BF, three regions were distinguishable which were related to land cover in the safety eco-field process. The experimental framework confirms the adequacy, at least for birds that have cryptic predators, to map the landscape as a proxy of safety resource. From the video recordings it was noted that the European robin visits were distributed throughout the day without apparent temporal preferences, while the great tit visits were concentrated in the central part of the day. This result has the limitation of the short period of observation (March) and should be extended to the entire period of the experiment to eventually capture seasonal variation. The experimental evidence obtained confirms that the ecosemiotic-based models of safety eco-field are an efficient approach to explain bird feeding preferences and behaviours. (shrink)

This commentary on the argument by Jablonka & Ginsburg ( 2022 ) that unlimited associative learning (UAL) provides an evolutionary marker for the transition to consciousness raises the question, “Transition to what?” The proposal that a level of consciousness required for UAL would embody eight specific criteria is credible, but can a limited degree of sentience still exist in animals that lack some of the criteria? The article makes a compelling case that UAL could serve as a marker for the (...) transition to an evolutionarily sustainable level of consciousness, but this may be different from _minimal_ consciousness. Nonetheless, the insight of these authors provides an exemplary roadmap for research on the evolutionary emergence of subjective experience in early animal evolution. (shrink)

Teleological theories are often dismissed in the study of animal behaviour, because of both the anthropomorphic element, and the paradox of retro-causation. Instead, emergent properties of animal systems, such as those which drive behaviour and decision making, are generally deemed to be non-purposeful. Nonetheless, organisms’ interactions with the environment, including sensory processing, have long been subject to biological study, and the resulting models include Jakob von Uexküll’s functional circle (part of his ‘Umwelt Theory’). The functional circle is modelled on an (...) assumption of three- dimensional space containing matter and energy, and one-dimensional, linear time. Moreover, the function of such models relies upon feedback within biological systems, and generally assume that the functional feedback loops close. I argue that this is impossible, because a feedback loop cannot go back intime to close itself, and so whilst it may approximate closure in space, it does not close in the dimension of time. To address this problem, I propose a conceptual model where time is treated as having a three- dimensional structure, and is measured in terms of past, future, and subjective present, termed the ‘period,’ ‘present’ and ‘phase,’ respectively. Space and matter, meanwhile, occur as a two- dimensional intersect, in which three-dimensional emergent properties which occur ion time are embedded. The model relies on functional helices rather than circles, and the loops of each helix (unlike circular loops) never achieve closure. I explain how this therefore results in a biological system, based on both feedback and anticipatory probabilities, which is both autopoietic and teleological. I also provide examples of how the concept can be applied, using foraging behaviour as an example. I further propose the theoretical origin of such a system is ‘timing’ and ‘rhythm,’ both of which I argue have their origins in single cellular organisms’ chemotaxis and the associated gradient descent search.

How is time transformed when signs appear? In the sign system of the conditioned reflex, the sign (conditioned stimulus) reverses, changes the direction of time, and overcomes its unidirectionality and irreversibility. In a sense, there is a “return” to the past in the form of the future when the sign is introduced. The sign serves as a “Time machine” of sorts. The mechanism of time transformation is possible because a mirror is embedded inside the sign, the surface of which represents (...) the psychological present time. When past experience meets that surface in the present, it may be reflected in the form of a future event. In the course of reflection, time changes its direction: if earlier time flowed from the event (the cause), it subsequently flows to other events (the purpose). Previously inaccessible past experience is now projected into the present, “comes to life” in it and is transformed into the future. In humans, unlike in animals, signs of the second order appear. Inside the signs of the second order, a mirror is built in, and the experience of the past as a subject is reflected in the future form as an object. An individual has the opportunity to consider oneself externally as an object. It goes beyond the subjective form. Thus, secondary signs once again change time direction. Due to this phenomenon, time becomes doubly reversible: first it turns around in a conditioned stimulus, and then in a secondary sign. (shrink)

The aim of this commentary article is to discuss several problems in the distribution map for conscious organisms and suggest a different strategy to address their evolutionary development. I propose to complement the model of Unlimited Associative Learning (UAL) that Jablonka and Ginsburg present in their Target Article with the additional consideration of how body plans constrain the possibilities of evolution of the brain— in some cases blocking, in some others enabling its complexification and corporal integration. In my view, the (...) specific body plan of vertebrates has played a key role in the complexification and diversification of consciousness because it has favored an increasing integration between brain and body.

Stingless bees are among the most dominant pollinators in the south tropics. As such, the rational beekeeping of stingless bee species, called meliponiculture, is an ancient and relevant activity, related to sustainable agricultural development, and which connects traditional knowledge to innovation and novelty. Given the relevance of this topic, this paper discusses the possibilities of a semiotically mediated communication between humans and Meliponini (stingless bees). Zoosemiotics, as the studies of animal views of the world, is the ideal modelling system for (...) the investigation of the possibilities of mutual understanding between these two species. Starting from the premise that, for there to be inter-specific communication, there must be a shared code, and that this depends on the biological makeup and sensory apparatus of both organisms involved in the communication process, this research suggests that a possible way to communicate with stingless bees is with the use of olfactory (chemical) signals, since this channel seems to be common to both humans and bees. Considering that for human-animal relations one party must be able to recognize the other (iconic learning), it is revealed that chemical signals do allow bees to recognize individual humans, even going so far as profiling this person as ‘not a threat’. Finally, bees are seen to act cooperatively while the beekeeper is taking action to protect and maintain the nest, something that can be interpreted as an opening of semiotic relations, where the bees are deeming the beekeeper as part of their social group.

The Romantic- and Revolution-era French naturalist Jean-Baptiste Lamarck is an important precursor for Jablonka’s and Ginsburg’s theory of living beings as beings that learn. Lamarck defined living beings as beings that compose and create. Like Jablonka and Ginsburg’s learning theory, Lamarck’s composing and creating theory locates life in the capacity for a kind of purposeful striving. A consideration of his theory can suggest fundamental questions for Jablonka and Ginsburg regarding the relations among what they call “vivaciousness,” the state of living (...) organisms, learning, and evolutionary transformation.

The call for a biosemiotic perspective within medical semiotics has been steadily increasing over the late twentieth and early twenty-first centuries. In _Food and Medicine: A Biosemiotic Perspective_, Yogi Hale Hendlin, Johnathan Hope, and the nine contributions in their edited volume boldly seek to bridge the segregation between nature and culture in the medical sciences as well as in the medical humanities. To a large extent, they achieve this aim by explicating the sign relations _in_ food and medicine, the sign (...) relations _of_ medical theory and practice, and the sign relations _between_ the biology in medicine and medicine of society. Taking up a semio-historical approach, I contextualize two select contributions from Hendlin and Hope’s _Food and Medicine_ with the medical semiotics of the Hippocratic tradition. By comparing the biological semiotics from the contributions to the medical semiotics from the Corpus, I critically explicate the ways in which biosemiotics moves this subdiscipline forward and why the perspective is significant not only for the health of humans, but also for the health of other animals, and indeed for the health of the planet that we all inhabit together. On these grounds, I propose a turn from medical semiotics to _health semiotics_. This program for semiotics would encompass not only food and medicine, but also lifestyle and wellbeing, as well as the subjective, qualitative perspectivism that makes biosemiotics frontier research, thereby constituting a biosemioethics and promoting a semiotic fitness.

The physical and relational structure of the biologic continuum (both internal and external to the organism) creates the information signature that is the basis for the origination of meaning in the living system. A meaning metric can be grounded in the significance of that information to the stability of the system during the process of adaptive reconciliation of divergences from the steady state condition. From this perspective, an information-theoretic formulation of the process for translating incident information into adaptive action is (...) proposed that can be practically used in defining and quantifying the meaning of that information for the living system.

Almost forty years after Adolf Portmann’s death, we welcome the publication of a collective monograph about the life and legacy of this unique zoologist and anthropologist. This work should be of interest to biologists who study the theoretical aspects of animal morphology or are interested in animal patterns, but also to philosophers of biology who investigate the aesthetic aspects of nature or the concept of organism. Intellectuals interested in these subjects – or non-mechanistic views of living beings in general – (...) are likely to be familiar with Portmann’s work, but this publication offers a look at various facets of his thought which are likely to be novel and of interest even to intellectuals already familiar with his thoughts.

The goal of this paper is to explain the evolution of life through the evolution of cellular and supra-cellular closures, two distinct ways of strict delimitation against the surroundings. Such closures are a necessary precondition of organisation, semiosis, and agency. We argue that in addition to the basic, first-order, cellular closures, which have been in existence without interruption since the dawn of life, there also exist second-order closures (cell communities), which are dynamic and often formed ad hoc. Moreover, a living (...) entity may belong simultaneously to different kinds of such second-order closures. It is these second-order closures which organise cellular (and higher-order) communities and form the core of the bonds that hold the biosphere together. In second-order closures, there exist countless crisscrossing pathways leading to manifold interpretations of particular situations. We provide examples of such relationships and point to an elaborate network connecting all denizens of the biosphere. (shrink)
