Division of Labour (DoL) among group members reflects the pinnacle social complexity. The synergistic effects created by task specialization and sharing duties benefitting raise efficiency acquisition, use, management defence resources a fundamental step above potential individual agents. At same time, it may stabilize societies because involved interdependence collaborators. Here, I review conditions associated with emergence DoL, which include existence (i) sizeable groups enduring membership; (ii) improving performance; (iii) low conflict interest owing to correlated payoffs. This results in (iv) combination intra-individual consistency inter-individual variance carrying out different tasks, creates (v) some degree mutual members. DoL typically evolves ‘bottom-up’ without external regulatory forces, but latter gain importance at later stage evolution Owing feedback processes, cause effect are often difficult disentangle evolutionary trajectory towards structured well-developed their Nevertheless, entail one-way street complexity, retrogression getting increasingly more agents depend on each other progressing stages evolution. article is part theme issue ‘Division labour as key driver evolution’.

Disruption of collective behaviour correlates with reduced interaction efficiency

Group-living organisms commonly engage in collective behaviour to respond an ever-changing environment. As animals face environmental change, establishing the mechanisms of information used collectively behave is critical. Western honeybees ( Apis mellifera ) are highly social insects that tightly coordinate many individuals ensure optimum colony function. We fanning, a thermoregulatory depends on both and thermal contexts, as case study for behaviour. To identify potential behind coordination we oxytetracycline, antibiotic apiculture known pollutant impairs bee physiology Specifically, hypothesized interactions drive fanning response predicted oxytetracycline would disrupt which will lead reduced response. found longer exposure antibiotics decreases fanning. Using automated tracking, show treatment reduces number interactions, impeding dynamics within these small groups. Our results contribute strong evidence between may honeybees. This work emphasizes importance understanding underlie animal how effects pollutants individual can scale affect populations.

Evolutionary biology of social expertise

There is increasing evidence that competent handling of social interactions among conspecifics has positive effects on individual fitness. While variation in competence been appreciated, the role long-term experience acquisition superior skills received less attention. With goal promoting further research, we integrate knowledge across disciplines to assess expertise, defined as characteristics, and allowing individuals with extensive perform significantly better than novices a given task. We focus three categories behaviour. First, animals can gain from adjusting behaviour towards individually recognised they interact regular basis. For example, there some territorial recognise their neighbours modify based each neighbour. Similarly, group-living species learn associate specific group members expected benefits such connections. Individuals have also found devote considerable time effort learning about spatial location timing sexual receptivity opposite-sex optimise reproduction. Second, signallers enhance signals, receivers refine response signals experience. In many birds insects, produce more consistent experience, females wide taxonomic range adaptively adjust mating preferences after perceiving distinct male signals. Third, species, succeed reproducing encounter novel, complex task caring for vulnerable offspring. Evidence few mammals indicates mothers improve providing protecting young over successive broods. Finally, expertise evolve, heritable be positively associated Heritable shown traits contributing including attention, empathy, recognition maternal care. are currently limited data associating fitness, most likely owing sparse research effort. Exceptions include care, signal refinement, familiarity members. Overall, keep refining throughout life. Hence propose promising lines quantify thoroughly development its
