i guess it could be in the way that birds have hollow bones
No it makes them fly
Solid Bones A+
their bones are hollow to make them lighter, and more legible for flight. if they had solid bones they wouldn't be able to fly as fast, high or as maneuverable as they are now. Hope this helped! (:
No, penguins have solid bones like other birds, which helps with their diving abilities and survival in the water. Hollow bones are found in flying birds to reduce weight for easier flight.
they are hollow to be more aerodynamic
Hollow bones in birds are an adaptation for flight because they reduce the overall weight of the bird, making it easier for them to take off and stay airborne. The air-filled cavities within the bones also provide structural strength and help to support the stresses of flying.
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly.
Bird bones are hollow and very thin or at least most of them are. Some are air filled and others have trusses or cross walls to make them strong. They also have fewer bones than mammals or reptiles of similar size. The skeleton is more rigid. These are factors which help a bird to manage flight.
So that the bird is not too heavy to fly and to aid in the intake of oxygen as the bird breaths in flight.
Penguins do not have skeletons that are identical to humans certain things are different such as bone length and the presence of a tail in the penguin. But certain structures are referred to as homologous. example: the flipper in the penguin and the arm and hand of a human have the same bone structure just different bone lengths.
Birds have hollow bones. (Except for penguins, which now have solid bones to help them dive)
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly. They have crisscross structures to add support inside the bones.
