What specific skeletal/jaw characteristic defines membership in Class Aves?
Answer
The presence of toothless beaked jaws
Class Aves is defined by a suite of distinct characteristics that allow for flight and high metabolism, and among these are specific features related to feeding and structure. A key defining trait is the adaptation of the jaw structure into a lightweight, toothless beak, often covered in keratin. While Class Aves also requires feathers, a high metabolic rate, and a four-chambered heart, the presence of these specialized beaks is a primary morphological criterion used in defining the class, separating birds from other classes like reptiles or mammals that possess teeth or different jaw structures.
