  • An investigation of the subpectoral diverticulum—an inflatable air sac structure between the major flight muscles—in 68 avian species reveals that the respiratory system has a role in the mechanics of flight in soaring birds.

  • Here, the authors track the evolution of mass distribution through bird evolution challenging suggested coupling between body shape and centre-of-mass position, and instead showing that crouched bipedalism evolved after powered flight.

  • Here, the authors examine how body size, shape, and segment proportions correspond to ecology in models of 410 tetrapods. They find variable allometric relationships, differential scaling in small and large animals, and body proportions as a potential niche occupation mechanism.

  • Unlike the tidal (in and out) breathing of mammals, bird lungs have unidirectional airflow patterns; here the savannah monitor lizard is shown to have unidirectional airflow too, with profound implications for the evolution of unidirectional airflow in reptiles, predating the origin of birds.

  • The origin of the unique turtle lung ventilatory apparatus is poorly understood. Here the authors show an increase in body wall rigidity early in evolution that allowed the abdominal muscles to become specialized for breathing and the ribs to eventually form the iconic turtle shell.
