"[...] a team of Danish researchers has designed a surprisingly “organic” model for the inside of an airplane wing by harnessing the immense computing power of 8,000 CPUs. In a letter published in Nature, Niels Aage and colleagues from the University of Denmark showed off an intricately curved and fractal-like airfoil design that’s strikingly similar to the interior of a bird’s wing and beak."

"The habits and anatomy of birds are being used by boffins at Airbus to develop quieter and more fuel efficient planes. The aviation giant, which makes and designs wings in Broughton, Flintshire, and Filton, Gloucestershire, employs Professor Norman Wood to unlock the mysteries of the natural world to help gain a commercial advantage.

Researchers are developing a bio-inspired unmanned aircraft capable of soaring like birds, boosting energy efficiency and endurance. The research team is aiming to be the first in the world to demonstrate an autonomous unmanned aircraft that can mimic birds by using updrafts around buildings to stay airborne.

"Boeing Co. and NASA have found an inexpensive way to cut airline fuel bills by borrowing a trick from the world’s greatest long-distance aviators: migratory birds. By lining up cruising aircraft in a V-shaped formation favored by Canada geese, carriers would be able to produce a leap in efficiency without investing in structural makeovers or futuristic technology. The idea is to link the flying convoys safely using navigation and collision-avoidance tools that already are widely installed in cockpits."

"[...] In a macroscopic axis, the A350 XWB considers the actively deformation of the surfaces to provide the best aerodynamic performance and control of load for each flight conditions; takeoff, climb, cruise, approach, landing, maneuver, turbulence-encounters, etc. This is what birds, fish and marine mammals perform beautifully, called "morphing". The idea is to move from a 'rigid' world to flexibility and adaptation technologies."

The design evolution process never ends. There are some robust associations between features that guide the designs which live longer.
In other words, the best design today will eventually be replaced by tomorrow's best of "de jour".

"The mystery of why so many birds fly in a V formation may have been solved. Scientists from the Royal Veterinary College fitted data loggers to a flock of rare birds that were being trained to migrate by following a microlight. This revealed that the birds flew in the optimal position - gaining lift from the bird in front by remaining close to its wingtip. The study, published in the journal Nature, also showed that the birds timed their wing beats."

Flying commercial planes in formation much like birds do has been conceptualized as a way to save fuel by flying in formation: http://www.triplepundit.com/2009/08/taking-cues-from-birds-to-green-the-airline-industry/
