Chapter 5 Dispute: Humans and Sharks both have four gill arches as embryos, but the germ layers and arches develop into unrelated structure in each organism
My Dispute Statement: Both sharks and humans develop gill arches when enveloped in the embryo, with the arches creating very similar structures and functions in both. In humans during conception, 4 swellings appear on the throat area. These swellings called arches develop to create many of the structures and functions inside the head. “When you follow what happens to the blobs and creases you begin to see the order and beauty of the head, including the trigeminal and facial nerves” (87). These arches soon develop muscles, tissues, and vessels inside the head creating a complex system. …show more content…
Similarities from the yolk stages of many organisms make it easy for scientists to relate their research to other organisms for stronger results. “The fish, amphibian, and chicken embryos were like nothing I had ever seen before in biology. They all looked generally alike” (98). Knowing how similar these organisms are in the yolk stages helps scientists understand the differences in the development of these organisms. The yolk stages really define how a-like these organisms are and how we have a inner-fish, inner-frog, inner-anything. For instance, they all had heads, brains, gill arches, and the structures that developed them, germ layers. Knowing how similar the development of these organisms are can lead scientists to back up related scientific experiment of other …show more content…
“The glue is not one thing; it is a variety of different molecules that connect and lie between our cells” (123). This glue and molecular structure gives each cell and tissue their distinct functions. What makes many different body parts different is how the materials like cells and tissues are arranged and attached to each other, like the eye and leg. This indicates that every tissue alignment is different in it’s own way and can be identified with it’s organism. The author had his students try to identify each tissue under a slide and it is possible, but very
