    THE SINUS BATTLE What Are Sinuses? Sinuses are air pockets found in the cranial (head) bones and are also referred to as “paranasal sinuses”. They are linked to the nose on the face where air passes and mucus drains. We have eight sinus cavities in total. They are paired on equal sides of our face, resulting in four pairs of sinus cavities. Each cavity has an opening called an ostium, leading to the nasal passages to exchange for air and mucus. The mucus linings have cells with fine hairs called

In this essay I am going to explore the

However, the adult humans lack two of these significant characteristics, which are the post-anal tail and the notochord. Furthermore, humans are classified as chordates due to the similarities within characteristics. For example, humans posses the

    An example of this is that flying insects, birds, and bats have all evolved the ability to fly independently. Darwin also proved common descent by observing similarity in the embryology of all vertebrates. He observed that developing embryos are identical at certain stages, and then different features develop, such as gill pouches in tetrapod embryos. Two creatures are more closely related the longer their developing embryos stay similar. Vestigial
