Quizplus · Accepted Answer

Modern birds have evolved to have a highly-specialized wing composed of fused and reduced skeletal elements, such as the fusion of the wrist bones to form the carpometacarpus and the reduction of digits in the hand. This adaptation allows for the development of powered flight, which is a distinguishing feature of birds.
