Your Inner Fish: A Review of Chapter 4 In Your Inner Fish‚ a book about the study of evolution in mammals‚ chapter four is dedicated to the study of teeth. Neil Shubin is explicit in his insistence that teeth are extremely important when studying evolution of the human body. He uses three main points to explain this to the reader. First‚ through the function of teeth. Then by revealing the anatomy of teeth. And finally by discussing tooth-to-tooth occlusion. Teeth are used to manipulate larger objects

Academia Interamericana de Panamá Science Speech Written Report *Geologic time* Aleks Ch. # 8 Date: 24/07/2013 Introduction The age of Earth is as vast in time as the universe is vast in space. It is not easy to really get a "feel" for 4‚600 million years! One way to try to get a "feel" for how big it is‚ is to break the number down into smaller pieces that perhaps we can understand. Plants and animals have changed many times‚ from amoebas to dinosaurs to people. The

Fossils A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground‚ the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from a creature or plant (like a bone). Trace fossils are signs of

Pangea supercontinent from space‚ as it may have looked 300 million years ago. The Earth is a little over 4.5 billion years old‚ its oldest materials being 4.3 billion-year-old zircon crystals. Its earliest times were geologically violent‚ and it suffered constant bombardment from meteorites. When this ended‚ the Earth cooled and its surface solidified to a crust - the first solid rocks. There were no continents as yet‚ just a global ocean peppered with small islands. Erosion‚ sedimentation and

Neo-Darwinism is the name given to the new age and evidence supporting the theory of evolution which includes the evidence discovered by Darwin and Wallace as well as newly found modern evidence. Neo-Darwinism builds onto previously discovered evidence and combines it with the modern evidence to form strongly supported hypotheses and evidence to support the theory of evolution. Evidence include that of the fossil record‚ comparative anatomy and embryology‚ as well as molecular biology and experimental

In 1969‚ Stan Taylor began excavating an area of the Paluxy River bed in Glen Rose‚ Texas. This river runs through the middle of Dinosaur Valley State Park and is infamous for its dinosaur tracks. In the particular section of the river in which Taylor was working were both tracks of a dinosaur and a human which had been preserved in the mud. A cross section showed the pressure exerted By each and the human print showed more pressure on the ball and heel of the foot forming the arch in the mud

For me‚ the obvious pick was the Triceratops. Like the Tyrannasaurus Rex‚ the Triceratops was quite popular in the Jurassic Park films. It was mostly known for its three huge horns and long stretched out neck frill (protecting its neck). Unfortunately‚ the movies and cartoons depicted the Triceratops poorly because it in fact wasn’t capable of charging at larger predators and withstanding the punishment with its skull. Triceratops skulls have been found with Tyrannosaurus Rex toothmarks clearly‚
