In humans and other gregarious animals, collective decision-making is a robust behavioural
feature of groups. Pooling individual information is also fundamental for modern societies, in …

Evolution selects for traits that are of adaptive value and increase the fitness of an individual
or population. Numerical competence, the ability to estimate and process the number of …

Investigations of collective movement and animal communication have often followed
distinct, though complementary, trajectories. Both subfields are deeply concerned with how …

Conflict can profoundly affect individuals and their groups. Oftentimes, conflict involves a
clash between one side seeking change and increased gains through victory and the other …

Abstract The contribution by De Dreu and Gross oversimplifies the complexity of the topic. I
provide counterarguments that undermine the two sweeping contentions on which the …

Cooperation and communication likely coevolved in humans. However, the evolutionary
roots of this interdependence remain unclear. We address this issue by investigating the role …

Although uniquely destructive and wasteful, intergroup conflict and warfare are not confined
to humans. They are seen across a range of group-living species, from social insects, fishes …

The patterns and mechanisms of collective decision making in humans and animals have
attracted both empirical and theoretical attention. Of particular interest has been the variety …

The earliest studies of collective animal behaviour were inspired by and conducted in the
wild. Over the past decades much of the research in this field has shifted to the laboratory …

Cognition, defined as the processes concerned with the acquisition, retention and use of
information, underlies animals' abilities to navigate their local surroundings, embark on long …
