Selection shapes diverse animal minds.

This special issue explores the evolution of cognitive diversity across the animal kingdom, challenging the value of approaches that have a basis in human psychology in favour of a perspective that embraces the multiple evolutionary endpoints that natural selection has produced. This approach centres around the key role of sensory processing as integral to cognition, rather than as something to be disentangled from it; around the relevance of so-called 'simple' processes; around the constraints that shape evolutionary trajectories and around the nonlinear nature of the selective environment. The field is advancing through approaches that span neuroscience, theoretical modelling, field studies, population genetics and more. By reframing cognition as a set of solutions to the natural world's many challenges, we move closer to understanding animal minds as reflections of the numerous ways life has evolved to make use of information.This article is part of the Theo Murphy meeting issue 'Selection shapes diverse animal minds.'
