Chickens and humans are vertebrates, so they share certain characteristics, such as the bones that form the upper limbs.
Although they have different shapes or sizes, the same bones that are in the human arm can be found in the wings of birds, in this case, of a chicken.
Humans and chickens both have humerus (light brown), radius and ulna (white and red), carpus (yellow), and metacarpus and phalanges (dark brown).
