Radial patterns of cell morphology in the Drosophila larval wing emerge through mechanosensitive dynamics of cell polarity.

Maneuverability is thought to be limited by either intrinsic constraints or physiological capacity, and automated tracking of flying hummingbirds reveals that muscle capacity explains much of the variation in their flight trajectories.

Hundreds of fossil remains shed new light on the evolution of grasshoppers, gryllids, and katydids and their ecological role 300 million years ago.

Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.

New digital restorations indicate that the structure and function of the shoulder joint were highly variable among Early Cretaceous birds, with such key features as the configuration of the triosseal canal and the nature of scapula-coracoid articulation showing considerable diversity.

Flight system of flies is driven by wings and mechanosensory halteres that operate as independently driven but coupled oscillators, thereby imparting robustness against wing or thorax damage.

Feathered feet of pigeons and chickens result from a partial molecular and morphological transformation of legs to a wing-like identity.

A novel mathematical strategy for the integrated analysis of adult body structures quantifies the degree and nature of developmental robustness and its evolutionary implications.

A new taxon from the Late Jurassic of southern Germany represents the second volant bird known from that time period and documents the improvement of flapping flight in bird evolution.

Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.
