Neil and his colleagues focused on rocks from 375 million years ago because fossils from 360 million years ago were amphibians with necks and four legs. However rocks that are 380 million years old looked more like fish we know today, with fins and scale. So, it made sense that they would find the transitioning fossils in rocks that was 375 million years old. Neil chose to look in sedimentary rocks, such as limestone, sandstones, siltstones and shales, because they form fossils gently since they generally are formed by rivers, lakes and seas. At first, they were looking for fossils in the Devonian rocks in Pennsylvania, but they did not have much luck since the rocks had too much exposure. So they found that the High Arctic of Canada was ideal because the rocks were 375 million years old, they were sedimentary and had little exposure.

The hedgehog gene helps make a region of the body different from another region and is found in limbs. This gene is active in ZPA. Cliff Tabin, Andy Macmahon and Phil Ingham attached a molecule of the hedgehog gene to see where it was active in the chicken. They found that iw is active in the ZPA. If the gene didn’t turn on when it’s supposed to, then we’d have extra finger of our pinkie and thumb would look alike. Randy Dahn ran similar experiments on sharks and Skate He saw that the gene turns on at the same time as in chickens. Also it is turned on in the back of the fin aka the pinkey. When they treated it with a vitamin A, it turned the gene on in the opposite side of the fin as well. Later he took a hedgehog gene from a mouse and placed it between identical skeletal rods of a skate. The rods responded to the gene.

Your Inner Fish Book Review
1569 Words | 7 PagesAs a secular person who takes an interest in science, I have always been fascinated by the academic field of evolutionary biology. Because of this, it should come as no surprise to anyone that the book I chose to review is entitled Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body. Written by Neil Shubin, this piece aims to outline the origins of humanity, as well as present a plethora of compelling pieces of evidence for the theory of evolution. He does this by reviewing scientific discoveries in areas of comparative anatomy, genetics, and the examination of fossils. Interestingly enough, he also integrates some of the most basic senses that we possess, such as sight and smell.

The maltreatment is believed to have led the death of several trainers in Canada, America, and Spain, as the killer whales grew increasingly agitated with their conditions.
