An enormous amount of work has been done on aging in Drosophila melanogaster, a
classical genetic and molecular model system, but also in numerous other insects. However …

The ecological dominance of ants has to a great extent been achieved through their
collective action and complex social organization. Ants provide diverse model systems to …

Human brain size nearly quadrupled in the six million years since Homo last shared a
common ancestor with chimpanzees, but human brains are thought to have decreased in …

Division of labor, the specialization of workers on different tasks, largely contributes to the
ecological success of social insects [1, 2]. Morphological, genotypic, and age variations …

Desert ants of the genus Cataglyphis undergo an age‐related polyethism from interior
workers involved in brood care and food processing to short‐lived outdoor foragers with …

The controversy concerning the extent to which the organization of division of labor in social
insects is a developmental process or is based on task allocation dynamics that emerge …

The mushroom bodies are high‐order sensory integration centers in the insect brain. In the
honeybee, their main sensory input regions are large, doubled calyces with modality …

Summary 1 Commonly held views assume that ageing, or senescence, represents an
inevitable, passive, and random decline in function that is strongly linked to chronological …

The social brain hypothesis assumes the evolution of social behaviour changes animals'
ecological environments, and predicts evolutionary shifts in social structure will be …

How does the sensory environment shape circuit organization in higher brain centers? Here
we have addressed the dependence on activity of a defined circuit within the mushroom …
