Question

How are the chicken wing and human arm similar, different, and how they are adapted to allow the organism to survive in their environments? they can bend and they have the same bones and ligaments?

Answer 1

They are similar just like a human and a whale are. Both are descended from a common ancestor! They adapt over time such as the whale's pelvic bone which is does not use anymore.

Answer 2

They share similarities in their tissue and cartilage. Both humans and chickens have epithelial tissue, muscle tissue and connective tissues; as well as cartilage to support the joints between bones. The bone structure is similar as well. Both animals have a humerus, which connects the shoulder and radius. Unlike humans, chickens can't move their metacarpals. Chicken bones are also hollow, making them lighter and more built for flight. Our arms are made more for grabbing, lifting and picking things up.
Hope this helps!
