    Differences Between Chicken Bones and Human Bones

    Humans have dreamed about flying for hundreds of years as flying has the connotations of ultimate freedom. There are some crucial differences in physiology and anatomy between humans and birds which make it possible for birds to fly and leave us with our feet firmly on the ground. This article will highlight the differences between human bones and chicken bones. %%AFC-ADVERT%%

    Things to Think About:

    • As an order you will find that birds are very similar; they all have feathers and wings. While it is true that not all birds can fly their bodies are still adapted for speed of movement whether in flight, walking, gliding or swimming.
    • Birds that fly have a rigid support system which is why they have less chicken bones than we have human bones. To fly birds have to have a larger percentage of muscle and their sternum looks like a keel of a boat rather than the flat shape of a human sternum.
    • Chicken bones and bird bones in general have air pockets and in some cases the leg bones are entirely hollow.
    • Humans have evolved focusing on one form of movement; walking. This means out bodies have adapted a complex skeletal structure with supportive connective tissue to get us from place to place.
    • If humans could fly how would our bodies be different? The length of our arms would change for certain, an albatross weighing 25 pounds has a wingspan of 11 feet comparing this to a human we would have to have a wingspan of at least 30-40feet to fly dependent on speed.
    • Human bones and chicken bones are adapted for the lifestyle they have. Chicken bones are needed for flight, even if it is in short stints, and their weight is a serious factor contributing to weather they can and cannot fly.
