New research based on high-resolution x-ray movies reveals that despite having extremely underdeveloped muscles and wings, young birds acquire a mature flight stroke early in their development, ...

Bird-bone structures emerge from an evolution-like algorithm. Engineers have used a supercomputing technique that mimics natural selection to design the internal structure of an aircraft wing from ...

Scientists have compared the relationship among the strength of flight bones, body mass, and the way modern birds fly to better understand the evolution of flight in birds and extinct animals, such as ...
