Abstract: The retina is a highly specialized neural tissue that encodes information of vision, a vital sensory modality for most species. Although the retina also contributes to other non‐image‐forming signals (e.g. entrainment of circadian clocks), vision chiefly enables animals to interpret and navigate their environment (despite the diverse variety of species and lifestyles; Baden et al., 2020) and also to interact with other animals. Thus, features such as high visual resolution and color discrimination are important for interactive behaviors like prey capture and also for social animals, including primates, that establish a dominance hierarchy.
