Social insects show us very little about the evolution of complex human society. As more relevant literature demonstrates, ultrasociality is a cause rather than an effect of human social evolution.

Fisher recognized that the evolution of social insect colonies needed explaining, a point which Charles Darwin had avoided discussing in detail. Fisher, in his 1930 book The Genetical Theory of Natural Selection, outlined in detail how eusociality could evolve, and developed a verbal model by connecting selection on fecundity with the sterility of workers. Fisher saw social insect colonies as harmonious units, in contrast to human societies that exhibit intra-communal conflict. Fisher’s development of the model was strongly influenced (...) by his correspondence with Leonard Darwin, and so I call it the Fisher-Darwin model. However, Fisher was not influenced by Lamarckian views on the evolution of social insects that were common at that time. The Fisher-Darwin model presages almost exactly the mathematical model recently proposed by Nowak and colleagues. (shrink)

We marvel at the social complexity of insects, marked by anatomically and behaviorally distinguishable castes, division of labor and specialization—but how do such systems evolve? Insect societies are composed of individuals, each undergoing its own developmental process and each containing its own genetic information and experiencing its own developmental and experiential environment. Yet societies appear to function as if the colonies themselves are individuals with novel “social genes” and novel social developmental processes. We propose an alternative (...) hypothesis. The origins of complex social behavior, from which insect societies emerge, are derived from ancestral developmental programs. These programs originated in ancient solitary insects and required little evolutionary remodeling. We present evidence from behavioral assays, selective breeding, genetic mapping, functional genomics and endocrinology, and comparative anatomy and physiology. These insights explain how complex social behavior can evolve from heterochronic changes in reproductive signaling systems that govern ubiquitous and ancient relationships between behavior and ovarian development.

The study of alternative genetic systems and mixed modes of reproduction, whereby sexual and asexual reproduction is combined within the same lifecycle, is of fundamental importance as they may shed light on classical evolutionary issues, such as the paradox of sex. Recently, several such cases were discovered in social insects. A closer examination of these systems has revealed many amazing facts, including the mixed use of asexual and sexual reproduction for the production of new queens and workers, males (...) that can clone themselves and the routine use of incest without deleterious genetic consequences. In addition, in several species, remarkable cases of asexually reproducing socially parasitic worker lineages have been discovered. The study of these unusual systems promises to provide insight into many basic evolutionary questions, including the maintenance of sex, the expression of sexual conflict and kin conflict and the evolution of cheating in asexual lineages.

In this paper, I discuss how information theory has been used in the study of animal communication, as well as how these uses are justified. Biologists justify their use of Shannon’s information measures by the work they do in allowing for comparisons between different organisms and because they measure a quantity that is purported to be important for natural selection. I argue that there are problems with both sorts of justification. To make these difficulties clear, I focus on the use (...) of Shannon’s information measures to quantify the amount of information transmitted by the fire ant’s odor trail and the honeybee’s waggle dance. Both of these systems are relatively simple and well understood, and the application of Shannon’s information measure to these systems initially seemed very promising and relatively straightforward. They are therefore particularly suitable for revealing the benefits and difficulties of applying Shannon’s information measures to biological systems in general, and animal communication systems in particular.

Queen pheromones, which signal the presence of a fertile queen and induce daughter workers to remain sterile, are considered to play a key role in regulating the reproductive division of labor of insect societies. Although queen pheromones were long thought to be highly taxon‐specific, recent studies have shown that structurally related long‐chain hydrocarbons act as conserved queen signals across several independently evolved lineages of social insects. These results imply that social insect queen pheromones are very ancient and (...) likely derived from an ancestral signalling system that was already present in their common solitary ancestors. Based on these new insights, we here review the literature and speculate on what signal precursors social insect queen pheromones may have evolved from. Furthermore, we provide compelling evidence that these pheromones should best be seen as honest signals of fertility as opposed to suppressive agents that chemically sterilize the workers against their own best interests.

Much ink has been spilt in consideration of the once pervasive reliance on military metaphors to depict the relationships between science and religion in the nineteenth century. This has resulted in historically sensitive treatments of secularization; and the realization that the relationship between science and religion was not a bloody war between intellectual nation states, but a protracted divorce of former partners. Moreover, historians of science have been encouraged to throw off the yoke of the internalism–externalism debate, and to explore (...) the cultural boundaries that impinged upon practitioners of a natural knowledge of the world. Within the historiography of nineteenth-century science, this has resulted in many new perspectives on science and natural knowledge in relation to cultural control and authority. (shrink)

This article outlines the rationale for a molecular genetic study of social behavior, and explains why social insects are good models. Summaries of research on brain and behavior in two species, honey bees and fire ants, are presented to illustrate the richness of the behavioral phenomena that can be addressed with social insects and to show how they are beginning to be used to study genes that influence social behavior. We conclude by considering the (...) problems and potential of this emerging field. (shrink)

Insects factored as ‘symbols of instinct’, necessary as a rhetorical device in the boundary work of early social psychology. They were symbolically used to draw a dividing line between humans and animals, clarifying views on instinct and consciousness. These debates were also waged to determine if social psychology was a subfield of sociology or psychology. The exchange between psychologist James Mark Baldwin and sociologist Charles Abram Ellwood exemplifies this particular aspect of boundary work. After providing a general (...) background of the debates, I turn specifically to the writings of Baldwin and Ellwood between 1890 and 1936, tracing the use of insects as ‘symbols of instinct’.

Social policies are used to regulate how members of a society interact and share resources. If we expand our sense of community to include the ecosystem of which we are a part, we begin to develop an ethical obligation to this broader community. This ethic recognizes that the environment has intrinsic value, and each of us, as members of society, are ethically bound to preserve its sustainability. In assessing the environmental risks of new agricultural methods and technologies, society should (...) not freely trade economic gains for ecological damage, but rather seek practices that are compatible with ecosystem health. This approach is used to evaluate the environmental risks associated with genetically engineered insect-resistant trees. The use of insect-resistant trees is a biologically based pest control strategy that has several advantages over pesticide use. However, the use of genetically engineered trees presents particular ecological concerns because the trees are long lived and often are not highly domesticated. The main environmental concerns reviewed include: (1) adaptation of pests to the trees, leading to a non-sustainable agricultural practice, (2) transgenic trees producing environmental toxins, (3) insect resistance enhancing the invasiveness of the tree, causing it to become weedy or invade wild habitats, and (4) transfer of the transgene to wild or feral relatives of the tree, possibly increasing the invasiveness of weeds or wild plants. Some methods are available to offset these risks; however, the environmental risks associated with this technology have been poorly researched and need to be more clearly identified so that when we evaluate the risks, it is based on the best information obtainable. To fulfil an ethical obligation to the environment, public policies and government regulations are needed to preserve the sustainability of both the environment and the future of our production systems. A better understanding of both the ecological issues and of genetic engineering in general are needed on the part of citizens and policy makers alike to ensure that sound environmental decisions are made. Otherwise, the environmental benefits of this technology, mainly decreasing the use of more toxic pesticides in tree crops and forests, will either be lost or traded for other environmental hazards.

The article traces Nietzsche’s references to insects in his published and unpublished writings against the backdrop of his study of the entomological research of his time (esp. through his reading of Alfred Espinas’s Die thierischen Gesellschaften). The first part of the article explores how Nietzsche’s entomology allows us to add a posthumanist perspective to the more familiar poststructuralist readings of Nietzsche, as the entomological research he consulted offered him a model for understanding how rudimentary processes can lead to the (...) formation of structures and higher organizations with emergent properties. The second part of the article revisits Nietzsche’s conceptions of the will and the will to power against the backdrop of his references to insect sociality and the influence of Wilhelm Wundt. It shows that Nietzsche’s deconstruction of the will as an umbrella concept and his will to power are attempts to model the emergence of complex edifices from simple operations under which physical, psychological, and social phenomena must be thought to arise. The article concludes with a reflection of the social and political relevance of what Nietzsche identifies as modernity’s “disgregation of the will.”. (shrink)

Much insect sounding is beyond the limits of typical human hearing ability. This sonic separation is exacerbated by a socialized narrative of fear and avoidance of insects in many western societies. With the use of audio technologies to expand our senses, we can embrace opportunities to get to know sensory and communicative insect sound-worlds beyond our own. Ecological sound art – sound art that has an environmentalist intent – is a tangible and accessible means of listening to these sounds. (...) In the series Built Hidden Soundscapes, the primary author (Schonberg) composes imagined soundscapes existing solely of sounds that are beyond the limits of typical human hearing ability. In this article we introduce two compositions in this series, Reserva Florestal Adolpho Ducke and Pipeline Road. These compositions offer a temporary expansion of our aural senses that can increase listeners’ awareness of cryptic insect existences/ecologies. We suggest that this listening practice might prompt future auralization (sounding or hearing in the mind) of insect sound for the listener. (shrink)

This paper aims to demonstrate how museum collection sustainability is grounded in a range of concrete care practices that are social and material. It explores the unstable nature of heritage materials, drawing on the ecological approach of infrastructure and maintenance studies in the field of art and museums. To do this, I analyse the role of mundane operations in the daily functioning of an exhibition area, presenting data from fieldwork I conducted from 2015–2016 at the Musée du quai Branly (...) in Paris, which preserves collections of art and ethnology from outside Europe. I observed the museum's preventive conservation practices, which work to minimise the risks of material deterioration of heritage objects, focusing attention on stabilising the relationship between objects and their environments. These practices contribute to the construction of the temporalities of museum objects. In exploring the means and devices of preserving these heritage objects, the very assumption of perpetuation is destabilised. Environments continually unfold with the silent material metamorphosis of objects. The exhibition becomes a place of flows, where a multitude of entities circulate and cohabit at different scales, such as insects, dust, and powdery fragments. The daily human work of vacuuming, cleaning, trapping, and measuring provide a set of actions united with other entities engaged in the material life of the exhibited object. As we zoom in on the exhibition space, different timelines emerge that are inextricably linked to the different lives of the museum. (shrink)

The world of insects is at once beneath our feet and unfathomably alien. Small and innumerable, insects surround and disrupt us even as we scarcely pay them any mind. Insects confront us with the limits of what is imaginable, while at the same time being essential to the everyday functioning of all terrestrial ecosystems. In this book, the philosopher and historian of science Jean-Marc Drouin contends that insects pose a fundamental challenge to philosophy. Exploring the questions (...) of what insects are and what scientific, aesthetic, ethical, and historical relationships they have with humanity, he argues that they force us to reconsider our ideas of the animal and the social. He traces the role that insects have played in language, mythology, literature, entomology, sociobiology, and taxonomy over the centuries. Drouin emphasizes the links between humanistic and scientific approaches—how we have projected human roles onto insects and seen ourselves in insect form. Caught between the animal and plant kingdoms, insects force us to confront and reevaluate our notions of gender, family, society, struggle, the division of labor, social organization, and individual and collective intelligence. A remarkably original and thought-provoking work, A Philosophy of the Insect is an important book for animal studies, environmental ethics, and the history and philosophy of science. (shrink)

It has become increasingly clear that social learning and culture occur much more broadly, and in a wider variety of animal communities, than initially believed. Recent research has expanded the list to include insects, fishes, elephants, and cetaceans. Such diversity allows scientists to expand the scope of potential research questions, which can help form a more complete understanding of animal culture than any single species can provide on its own. It is crucial to understand how culture and (...) class='Hi'>social learning present in different communities, as well as what influences community structure and culture may have on one another, so that the results across these different studies may most effectively inform one another. This review presents an overview of social learning in species across a spectrum of community structures, providing the necessary infrastructure to allow a comparison of studies that will help move the field of animal culture forward.

Agriculture has long struggled to reconcile production with biodiversity conservation. Industrial farming practices that erode structural complexity within crop fields and across entire landscapes, as well as widespread pesticide use, have resulted in declining insect abundance and diversity globally. Recognition of socio-environmental consequences have spurred alternative pest management paradigms such as integrated pest management (IPM) and conservation biological control (CBC), which emphasize ecology as the scientific foundation for a sustainable agriculture. However, adoption of these approaches at scales large enough to (...) impact biodiversity has been slow, particularly in industrialized countries. Landscape-scale management is an integral component of ecological agriculture, making pest control and biodiversity conservation collective problems that require coordination among multiple stakeholders. The extent to which farmers recognize and act upon this perspective is not well studied. Through literature synthesis and a case study of Southern Wisconsin, I analyze factors shaping farmer adoption of insect and landscape management practices through the lens of constrained choice. I argue that multiple overlapping institutions (social networks, market forces, science and technology, and political-legal systems) co-produce farmer behaviors and landscape structure, largely to the detriment of ecological pest control and biodiversity. Wisconsin farmers' entomological concerns largely overlook beneficial insect species and eschew landscape thinking. Ultimately, slowing agricultural drivers of insect biodiversity declines will likely require large-scale coordination and political-economic change. (shrink)

The ArgumentThe vine lousePhylloxera vastatrixbecame a “pest” as it was transferred from North America and from France to Germany during the 1870s. Embodying the “invading alien,” it assumed a cultural position that increasingly gained importance in Imperial Germany. In this process, the minute insect, living invisibly underground, was made visible and became constitutive of the scientific-technological object, “pest,” pertaining to a scientific discipline, modern economic entomology. The “pest” phylloxera emerged by being made visible in a way that enabled control measures (...) against it. Thus, visibility functioned as a prerequisite for control measures. I differentiate between social visibility and physical visibility, as well as between social control and physical control of the “introduced pest.” The object phylloxera emerged at the intersection of techniques of social control such as surveillance, techniques of physical control such as disinfection, and representational practices of the sciences such as mathematics and graphics. The space of its visibility was not the vineyard as property of a vintner but the vineyard as national territory, where German (viti-) culture was defended against foreign infiltration and destruction. Many vintners had alternate visions of the grapevine disease, they resented the invasion and destruction of their vineyards by government officers, and thus they did not participate in the social and epistemic constitution of the “pest.” By 1914, the “introduced pest” had not yet become an effective “machinery.” However, the “pest” as an object of scientific knowledge emerged together with economic entomology. The field became organized as a discipline in Germany in 1913, forty years after the phylloxera had first aroused the minds of some worried Wilhelmians, and, together with its nationalistic images, the field of “pest” control became organized towards a redefinition of German society and its perceived dangers.

Insects and ‘the swarm’ as metaphors and objects of research have inspired works in the genres of science fiction and horror; social and political theorists; and the development of war-fighting technologies such as ‘drone swarms’, which function as robot/insect hybrids. Contemporary developments suggest that the future of warfare will not be ‘robots’ as technological, individualised substitutions for idealised (masculine) warfighters, but warfighters understood as swarms: insect metaphors for non-centrally organised problem-solvers that will become technologies of racialisation. As such, (...) contemporary feminist analysis requires an analysis of the politics of life and death in the insect and the swarm, which, following Braidotti (2002), cannot be assumed to be a mere metaphor or representation of political life, but an animating materialist logic. The swarm is not only a metaphor but also a central mode of biopolitical and necropolitical war, with the ‘terrorist’ enemy represented as swarmlike as well. In analysing the relations of assemblage and antagonism in the war ontologies of the drone swarm, I seek inspiration from what Hayles (1999, p. 47) describes as a double vision that ‘looks simultaneously at the power of simulation and at the materialities that produce it’. I discuss various representations and manifestations of swarms and insect life in science/speculative fiction, from various presentations of the ‘Borg’ in Star Trek (1987–1994, 1995–2001, 1996), Alien (1979) and The Fly (1958, 1986) to more positive representations of the ‘becoming-insect’ as possible feminist Utopia in Gilman's Herland (2015 [1915]) and Tiptree's Houston, Houston, Do You Read? (1989 [1976]). Posthuman warfare also contains the possibilities of both appropriating and rewriting antagonisms of masculine and feminine in the embodiment of the subject of war in the swarm. This piece seeks to analyse new ways of feminist theorising of the relations of power and violence in the embodiment of war as the swarm. (shrink)

Entomophagy—the practice of eating insects—has been touted as a means to combat undernutrition and food insecurity globally. Insects offer a nutritious, environmentally friendly alternative to resource-intensive livestock. But the benefits of edible insects cannot be realized if people do not choose to eat them. We therefore examine the social acceptability of edible insects in rural Zambia, where entomophagy is common but underexplored. Through a village case study, we show that edible insects are not valued (...) equally, are understood socially, and seem to reflect and reinforce social values. We utilize grounded theory and ethnographic methods, including semi-structured interviews, focus groups, and observation to examine collective entomophagy beliefs. While we expected to see differentiation in perceptions across groups based on kinship, we demonstrate that social values related to class, urbanism, gender, and age emerge as more germane explanations for entomophagy perceptions, reflecting their social weight. By expanding on current apperception of entomophagy behavior, our findings inform future research and efforts to promote entomophagy through minilivestock farming. Systems designed to maximize output, minimize labor, and highlight benefits are more likely to be widely accepted. We do not anticipate tribal association will be the primary limitation on minilivestock adoption in this context. (shrink)

Against the background of high demand for protein-rich feed in the EU and the environmental degradation associated with intensive livestock farming, insect-based feed is discussed as a potential sustainable alternative to conventional feed. However, the establishment of such an innovation depends not only upon technical and economic feasibility, but also on social factors impacting acceptability. The aim of this paper was to determine the acceptability of different social actor groups towards the use of insects as livestock feed, (...) and to gain insights into value-based arguments leading to positive or negative attitudes and perceived benefits and risks. By means of qualitative content analysis, we analysed responses of an EU public consultation process linked to the authorization of insect protein in pig and poultry feed. We found a broad range of value-based arguments that influence the complex judgement process of acceptability that have been neglected in prior quantitative surveys. In particular, our results bring forward more critical voices, such as animal welfare concerns and scepticism that insect-based feed can contribute to a more sustainable livestock system. Based on these findings, we discuss whether insects as feed are a viable contribution to a sustainability-oriented transformation of the agri-food system. We conclude that under certain conditions (when raised on low-value organic side streams such as manure) insect-based livestock feed may contribute to incremental sustainability improvements. Overall, however, the innovation has limitations, not only in terms of regulatory conditions but especially with regard to ethical concerns. (shrink)

The practice of early modern natural history depended on the collective collecting activities of a great variety of people. Among them, artisans played a major role in acquiring and distributing knowledge about the natural world and they contributed significantly to the scholarly labour in natural history. This distributed labour was both acknowledged by contemporaries as well as hidden from sight, reflecting the period′s dominant norms for class and gender. By combining an interpretation of the visual representation of labour in European (...) insect studies with an examination of written sources about natural history practices from about 1680 to 1810, this article decodes the often‐codified frontispieces and other more symbolic illustrations to offer new insights into the labour of natural history. Those who identified as scholars and artisans (or both) conceptualised their own intellectual and practical engagement with natural history within the semantic field of work. Some seemed to have even envisioned a new social role for academics as well as artisans. This article analyses the diversity of the “productive forces” in insect studies as they changed over time and it reconstructs what I will call the social imaginaries of participation. (shrink)

Summary This paper examines the entomological investigations carried out by the French naturalist Henri-Louis Duhamel du Monceau during a series of insect epidemics that ravaged France in the second half of the eighteenth century.1 This article began as a paper for Pamela H. Smith's ?Knowledge in Transit? graduate seminar. I would like to thank the participants of that seminar for comments and feedback. I would also like to thank Pamela Smith, Carl Wennerlind, Anya Zilberstein, Christopher L. Brown, Charly Coleman, Matthew (...) Jones, Peter Walker and Melissa Morris for their suggestions and comments on this paper. Finally, thanks to Vanessa Copeland for invaluable assistance in the archives in Paris. The author acknowledges support from the Social Sciences and Humanities Research Council of Canada and the Graduate School of Arts and Sciences, Columbia University. It shows how a particularly fierce invasion of caterpillars in the Angoumois region in the 1760s sparked theoretical debates about the nature of animal generation between academic naturalists, farmers, provincial officials and amateur naturalists. As part of a wider effort to reform agricultural production in France, Duhamel du Monceau sought to eliminate vernacular understandings of insect generation and to reform local pest control techniques. In his attempt to develop a body of pest-control knowledge grounded in the systematic observation of insect generation, however, Duhamel du Monceau relied heavily on the efforts of amateur naturalists. The paper shows how he mobilized a nation-wide network of entomological observers, and collected specimens and observational reports from farmers, improving landlords and local officials throughout France. Some informants did not only act as ?mere? observers, but formulated their own causal claims about insect generation that sometimes contradicted those of their metropolitan counterpart. Finally, it demonstrates that a ?patriotic? discourse that joined agricultural improvement and civic virtue provided a powerful impetus for the formation of collaborative relationships between academic naturalists, state officials and enlightened agricultural improvers.

Historians and philosophers of science have examined the relationship between language and practice for a long time. Scholars have made important contributions to the field by attending to the social, cultural and economic contexts in which scientific paradigms are created and re-created.

Normativity is widely regarded as the ability to make evaluative judgments based on a shared system of social norms. When normativity is viewed through the cognitively demanding lens of human morality, however, the prospect of finding social norms innonhuman animals rapidly dwindles and common causal structures are overlooked. In this paper, I develop a biofunctionalist account of social normativity and examine its implications for how we ought to conceptualize, explain, and study social norms in the wild. (...) I propose that we think of social normative systems as behavior-regulatory power structures that resolve conflicts between nested levels of selection in favor of the higher level. I argue that the best case for social norms outside of humans is not in the animals one might expect, such as primates or other large-brained vertebrates, but rather in social insects. Finally, I engage with a number of potential objections to this unorthodox proposal. (shrink)

The social organization of insect colonies has fascinated biologists and natural historians for centuries. Aristotle wrote in History of Animals about a division of labor among workers within the hive that is based on age. He observed that the field bees foraging for nectar and pollen have less “hair” on their bodies than the hive bees that care for young larvae and tend the nest. He concluded that the more pubescent hive bees must be older. We now know that, (...) in fact, the field bees are older and have less hair because the hairs break off as the bees age. The phenomenon of age related changes in behavior, age-polyethism, is now well documented for many social insects (Oster and Wilson 1978).Evidence of the ecological success of social insects is inescapable. Virtually everywhere you look you see them or the results of their activities. (shrink)

The kin selection theory has recently been criticised on the basis of claiming that genetic relatedness does not play a causal role in the social evolution among individuals of insect societies. We outline here a line of criticism of this view by demonstrating two things. First, there are strong conceptual, theoretical and empirical reasons to think that close genetic relatedness has been necessary for the rise of the helper castes of social insects. And second, once we understand (...) how causal explanation itself results from an interplay of two logically distinct elements, necessity and sufficiency, we can also understand the scenarios in which relatedness does not seem to play a causal role for evolution of helper castes. The result of this analysis is that we should be more careful about the way we frame the empirical data on the evolution of social behaviour. (shrink)

While unnecessarily killing or injuring an insect is arguably wrong, euthanasia of an accidentally injured insect raises anew issues of whether insects can experience pain. The question takes renewed significance due to increasing insect farming for food and feed and concerns over farmed insect welfare. For euthanasia of a damaged insect to be justifiable, the damage must be sensed as a noxious stimulus (nociception) that the insect consciously experiences as pain. This pain must then lead to suffering or frustrated (...) desire, with the possibility of the animal preferring death to continued existence. A failure at any of these points would deem euthanasia moot. The neurological, behavioral, and evolutionary evidence so far suggests the concept of euthanasia does not apply to insects. (shrink)

Dorion Sagan observes that pioneering ethologist Jakob von Uexküll tends to be read in contrasting ways, as a “humble naturalist” pre-empting current research in biosemiotics, animal perception and agency; and as a “biologist-shaman,” gesturing to a transcendental realm where the life-worlds of animals interconnect in a vast symphony of nature. In both cases the tools of the laboratory are thought to generate complete pictures of the invertebrates that Uexküll studies, in unity with their environments. As Giorgio Agamben points out, these (...) experiments form part of an abstract mechanism that produces the human, by isolating instinctual life as an object for study and management from social and ethical modes of existence. What these readings neglect to consider is that Uexküll imagines his experiments through a Picture Book frame. We argue that for Uexküll there is always something fabulous and child-like about the enterprise of reconstructing the subjective environments of the small animals he works with. Drawing on Bernard Stiegler, we propose the Picture Book as a particular technics, or tertiary memory, that cultivates modes of attention that are associated with childhood and are open to the emergence of partial objects and relations. Considered through the Picture Book frame, the Umwelten of insects and other small animals are no longer fixed but are drawn and redrawn in partial expressive ways, through the uncanny picturing – or what Brian Massumi would call “semblances” – of different configurations of animal, technology, human relations. By considering the Picture Book as a technic for ecological thought and imagination, our paper will explore how the small creatures that Uexküll describes might enable the emergence of new ethical sensibilities and relations.

Recently, psychological phenomena have been expanded to new domains, crisscrossing boundaries of organizational levels, with the emergence of areas such as social personality and ecosystem learning. In this contribution, we analyze the ascription of an individual-based concept (personality) to the social level. Although justified boundary crossings can boost new approaches and applications, the indiscriminate misuse of concepts refrains the growth of scientific areas. The concept of social personality is based mainly on the detection of repeated group differences (...) across a population, in a direct transposition of personality concepts from the individual to the social level. We show that this direct transposition is problematic for avowing the nonsensical ascription of personality even to simple electronic devices. To go beyond a metaphoric use of social personality, we apply the organizational approach to a review of social insect communication networks. Our conceptual analysis shows that socially self-organized systems, such as isolated ant trails and bee’s recruitment groups, are too simple to have social personality. The situation is more nuanced when measuring the collective choice between nest sites or foraging patches: some species show positive and negative feedbacks between two or more self-organized social structures so that these co-dependent structures are inter-related by second-order, social information systems, complying with a formal requirement for having social personality: the social closure of constraints. Other requirements include the decoupling between individual and social dynamics, and the self-regulation of collective decision processes. Social personality results to be sometimes a metaphorical transposition of a psychological concept to a social phenomenon. The application of this organizational approach to cases of learning ecosystems, or evolutionary learning, could help to ground theoretically the ascription of psychological properties to levels of analysis beyond the individual, up to meta-populations or ecological communities.

The role of genetic relatedness in social evolution has recently come under critical attention. These arguments are here critically analyzed, both theoretically and empirically. It is argued that when the conceptual structure of the theory of natural selection is carefully taken into account, genetic relatedness can be seen to play an indispensable role in the evolution of both facultative and advanced eusociality. Although reviewing the empirical evidence concerning the evolution of eusociality reveals that relatedness does not play a role (...) in the initial appearance of helper phenotypes, this follows simply from the fact that natural selection – of which relatedness is a necessary component – does not play a causal role in the origin of any traits. Further, separating two logically distinct elements of causal explanation – necessity and sufficiency – explains why the debate lingers on: although relatedness plays a necessary role in the evolution of helping and advanced eusociality, relatedness alone is not sufficient for their appearance. Therefore, if the relatedness variable in a given data set is held at a uniformly high value, then it indeed may turn out that other factors occupy a more prominent role. However, this does not change the fact that high relatedness functions as a necessary background condition for the evolution of advanced eusociality. (shrink)

Honeybees display a fascinating social behavior. The structural basis for this behavior, which made the bee a model organism for the study of communication, learning and memory formation, is the tiny insect brain. Neurons of the brain communicate via messenger molecules. Among these molecules, neuropeptides represent the structurally most‐diverse group and occupy a high hierarchic position in the modulation of behavior. A recent analysis of the honeybee genome revealed a considerable number of predicted (200) and confirmed (100) neuropeptides in (...) this insect.1 Is this quantity merely the result of advanced mass spectrometric techniques and bioinformatic tools or does it reflect the expression of more of these important messenger molecules, more than known from other insects studied so far? Our analysis of the data suggests that the social behavior is by no means correlated with a specific increase in the number of neuropeptides. Indeed, the honeybee genome is likely to contain fewer neuropeptide genes, neuropeptide paralogues and neuropeptide receptor genes than the solitary fruitfly Drosophila.

Persons are biological beings who participate in social environments. Is human sociality different from that of insects? Is human sociality different from that of a computer or robot with elaborate rules for social interaction in its program memory? What is the relationship between the biology of humans and the sociality of persons? I argue that persons constitute an emergent ontological level that develops out of the biological and psychological realm, but that is largely social in its (...) own constitution. This requires a characterization of the relationships between the bio/psychological and the social, and of the developmental process of emergence. It also requires a framework for modeling the bio/psychological level that makes any such emergence possible. Neither attachment theory nor information processing frameworks, for example, will do — the major orientations toward human sociality today make understanding that sociality ultimately impossible. Only an action framework, such as that of Peirce or Piaget2, suffices. (shrink)

We suggest that supergenes, groups of co‐inherited loci, may be involved in a range of intriguing genetic and evolutionary phenomena in insect societies, and may play broad roles in the evolution of cooperation and conflict. Supergenes are central in the evolution of an array of traits including self‐incompatibility, mimicry, and sex chromosomes. Recently, researchers identified a large supergene, described as a social chromosome, which controls social organization in the fire ant. This system was previously considered to be a (...) remarkable example of a single gene affecting a complex social trait. We describe how selection may commonly favor reduced recombination and the formation of supergenes for social traits, and once formed, supergenes may strongly influence further evolutionary dynamics within and between lineages. The evolution of supergenes, and even wholly non‐recombining genomes, may be particularly common in systems in which genetically distinct lineages can form mutually reinforcing socially parasitic relationships.

E.O. Wilson (1975) described humans as one of the four pinnacles of social evolution. The other pinnacles are the colonial invertebrates, the social insects, and the non-human mammals. Wilson separated human sociality from that of the rest of the mammals because, with the exception of the social insect like Naked Mole Rats, only humans have generated societies of a grade of complexity that approaches that of the social insects and colonial invertebrates. In the last (...) few millennia, human societies have even begun to exceed, in numbers of individuals and degree of complexity, the societies of ants, termites, and corals. (shrink)

Darwinian evolution, as it was first conceived, has two dimensions: adaptation, that is, selection based upon “apt function”, defined as the “good fit” between an organism’s metabolic and biological demands and the environment in which it is embedded; and heredity, the transmissible memory of past apt function. Modern Darwinism has come to focus almost exclusively on hereditary memory, eclipsing the—arguably still-problematic—phenomenon of adaptation. As a result, modern Darwinism retains, at its core, certain incoherencies that, as long as they remain unresolved, (...) preclude the emergence of a fully-coherent theory of evolution. Resolving the incoherencies will involve clarifying the relationship between embodied memory and apt function. In short, adaptation is a problem of semiotics: the organism must interpret the environment to fit well into it. This is well-illustrated by the constructed environments built by colonies of social insects, such as hives or nests, and the ancillary structures that contain them, forming an organism-like system known as a superorganism. The superorganism is marked by a kind of extended physiology, in that these constructed environments often serve as adaptive interfaces between the nest and ambient environment, and are constructed to manage the matter and energy flows between environments that constitute the process of adaptation. These constructed environments are also semiotic phenomena: interpretive structures, governed by information flow between the member insects and the structures they build. I review our findings on one such example: the mounds built by the fungus-cultivating termites of the genus Macrotermes. These structures are dynamic forms that are sustained by flows of soil from deep horizons up into the mound. The form, and hence the function, of the mound is determined by several environmental cues, most notably water and wind, as well as how termites interpret these cues, and signals that flow between termites, both directly and vicariously through the structures they build.
