To the present day, although a few studies have examined other aspects, the preponderance of research has concentrated on brief observations, predominantly examining collective action over time spans of up to a few hours or minutes. In spite of being a biological characteristic, considerably longer periods of time are essential for comprehending collective behavior in animals, especially how individuals evolve throughout their lives (a significant focus in developmental biology) and how they transform between generations (a key concern in evolutionary biology). Exploring collective animal behavior across various temporal dimensions, from immediate to extended, we underscore the need for further research in developmental and evolutionary biology to fully comprehend this phenomenon. Our review, constituting the opening chapter of this special issue, scrutinizes and encourages a broader comprehension of collective behaviour's development and evolution, thereby initiating a revolutionary approach to collective behaviour research. Part of the ongoing discussion meeting issue, 'Collective Behaviour through Time', is this article.

Research into collective animal behavior frequently hinges upon short-term observations, with inter-species and contextual comparative studies being uncommon. Accordingly, our knowledge of collective behavior's intra- and interspecific variations across time is limited, a fundamental aspect of understanding the ecological and evolutionary factors shaping collective behaviors. This paper explores the coordinated movement of stickleback fish shoals, homing pigeon flocks, goat herds, and chacma baboon troops. We present a description of how local patterns, characterized by inter-neighbor distances and positions, and group patterns, defined by group shape, speed, and polarization, vary across each system during collective motion. Taking these as our basis, we position the data for each species within a 'swarm space', promoting comparisons and predictions for the collective motion seen across species and various conditions. Researchers are requested to contribute their data to the 'swarm space' archive in order to update it for subsequent comparative investigations. Secondarily, we investigate the intraspecific variability in collective movement throughout time, and offer researchers a framework for determining when observations at differing time scales permit accurate inferences about species collective motion. This article is included in a discussion meeting concerning the topic of 'Collective Behavior Over Time'.

Superorganisms, comparable to unitary organisms, undergo a sequence of changes throughout their existence that impact the complex mechanisms governing their collective behavior. Genetic bases This study suggests that the transformations under consideration are inadequately understood; further, more systematic investigation into the ontogeny of collective behaviors is warranted to clarify the link between proximate behavioral mechanisms and the development of collective adaptive functions. Especially, some social insect species demonstrate self-assembly, creating dynamic and physically joined structures with striking resemblance to the development of multicellular organisms. Consequently, these insects serve as superb model systems for ontogenetic investigations into collective behavior. Nevertheless, a complete understanding of the varying life phases of the composite structures, and the progressions between them, necessitates a comprehensive examination of both time-series and three-dimensional datasets. Established embryological and developmental biological fields offer practical methodologies and theoretical blueprints, thus having the potential to quicken the acquisition of novel information regarding the development, growth, maturity, and breakdown of social insect self-assemblies and other superorganismal behaviors by extension. This review seeks to encourage a wider application of the ontogenetic perspective in the investigation of collective behaviors, especially within the context of self-assembly research, which has substantial implications for robotics, computer science, and regenerative medicine. The current article forms a component of the 'Collective Behaviour Through Time' discussion meeting issue.

The study of social insects has been instrumental in illuminating the beginnings and development of collaborative patterns of behavior. Evolving beyond the limitations of twenty years ago, Maynard Smith and Szathmary identified superorganismality, the sophisticated expression of insect social behavior, as one of the eight key evolutionary transitions in the increase of biological complexity. Despite this, the exact mechanistic pathways governing the transition from solitary insect lives to a superorganismal form remain elusive. An often-overlooked question regarding this major evolutionary transition concerns the mode of its emergence: was it through gradual, incremental changes or through clearly defined, step-wise advancements? lung viral infection We posit that a scrutiny of the molecular processes driving varying levels of social complexity, seen throughout the major transition from solitary to complex social arrangements, can shed light on this matter. We present a framework to analyze the impact of mechanistic processes during the major transition to complex sociality and superorganismality, particularly focusing on whether the underlying molecular mechanisms demonstrate nonlinear (implying stepwise evolution) or linear (implying gradual evolution) changes. Data from social insects informs our assessment of the evidence for these two modes, and we discuss how this framework allows for the testing of the generality of molecular patterns and processes across other major evolutionary events. 'Collective Behaviour Through Time,' a discussion meeting issue, features this article as a component.

The lekking mating system is a remarkable display, where males establish and tightly defend clustered territories during the breeding season, which females then frequent for mating purposes. This peculiar mating system's evolutionary origins are potentially explained by a spectrum of hypotheses, from the decrease in predation pressure to mate preference and the advantages of specific mating behaviors. Yet, a significant number of these classical conjectures seldom address the spatial processes that give rise to and perpetuate the lek. This article suggests an examination of lekking from a collective behavioral standpoint, where local interactions between organisms and the habitat are posited as the driving force in its development and continuity. Our perspective, moreover, highlights the temporal shifts in lek interactions, normally occurring throughout a breeding season, creating a profusion of broad-based as well as fine-grained collective patterns. We argue that evaluating these concepts across proximal and distal levels hinges on the application of conceptual tools and methodological approaches from the study of animal aggregations, such as agent-based models and high-resolution video analysis to document fine-grained spatiotemporal dynamics. Employing a spatially explicit agent-based model, we explore how simple rules, such as spatial accuracy, localized social interactions, and repulsion between males, can potentially explain the emergence of leks and the coordinated departures of males for foraging. Employing a camera-equipped unmanned aerial vehicle, we empirically investigate the prospects of applying collective behavior principles to blackbuck (Antilope cervicapra) leks, coupled with detailed animal movement tracking. A collective behavioral lens potentially yields novel insights into the proximate and ultimate factors that shape lek formations.

Environmental stressors have been the primary focus of research into behavioral changes throughout the lifespan of single-celled organisms. Yet, accumulating data implies that unicellular organisms display behavioral alterations across their entire lifespan, unconstrained by external conditions. We scrutinized the relationship between age and behavioral performance across various tasks in the acellular slime mold Physarum polycephalum. Slime mold specimens, aged between one week and one hundred weeks, were a part of our experimental procedure. Our findings illustrated that migration speed declined as age escalated, encompassing both beneficial and detrimental environmental conditions. Furthermore, our findings indicated that age does not impair the capacity for decision-making and learning. Old slime molds, experiencing a dormant period or merging with a younger relative, can regain some of their behavioral skills temporarily, thirdly. Ultimately, our observations focused on the slime mold's reactions to age-dependent cues emitted by its clonal counterparts. Young and aged slime molds both exhibited a pronounced preference for the cues left behind by their younger counterparts. While a wealth of research has focused on the behavior of unicellular organisms, a paucity of studies has examined the behavioral changes that take place during the complete lifespan of an individual. This study increases our understanding of the adaptable behaviors in single-celled organisms, designating slime molds as a promising tool to study the effect of aging on cellular actions.

Sociality, a hallmark of animal life, involves intricate relationships that exist within and between social groups. Intragroup relations, frequently characterized by cooperation, contrast sharply with intergroup interactions, which often manifest as conflict or, at the very least, mere tolerance. Remarkably few instances exist of collaborative endeavors between individuals belonging to different groups, especially in certain primate and ant communities. We address the puzzle of why intergroup cooperation is so uncommon, and the conditions that are propitious for its evolutionary ascent. The presented model incorporates local and long-distance dispersal, considering the complex interactions between intra- and intergroup relationships.
