Cambrian explosion

Way back when, humanity had such a strong past. Nothing appeared. Time was time. Nothing is nothing. The four eras that made history. Precambrian, Paleozoic, Mesozoic, Cenozoic. Historians and Scientists, did research for years and years. What happened during the Precambrian Era, nobody had a clue. Until humans researched the resources left behind. Back in the Precambrian Era . Earth was born. 4.6 million years ago, not even that many.! Stars and the planets were too! Rocks and much…

dominated by the Red Queen Effect, where it takes all of the evolutionary capabilities of a species just to stay in the same place on a larger scale, since all other organisms are evolving as well. However, large evolutionary events, such as the Cambrian explosion or the Permian extinction are a direct result of the shifting critical state though huge avalanches in the self-organized critical…

Byron Likdisha AP Biology Essay #2 The modern synthesis incorporated Charles Darwin’s theory of natural selection and many other fields of science, including genetics, to explain evolution more accurately. When Darwin wrote “On the Origin of Species “, he only explained the first mechanism of evolution, which was natural selection. The modern theory of evolution now highlights three more important mechanisms for evolution, which are mutations, genetic drift, and gene flow. Many…

Even before man, many things happened in what is today the state of Iowa. It begins in the Precambrian and Cambrian period which according to the website from UCMP Berkley, “The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears.” The exhibit then…

List and describe the six different periods into which the Paleozoic Era is divided The first period in the Paleozoic Era was the Cambrian Period. During this period there was a sudden explosion of life on earth. The climate of the Cambrian Period was relatively cold at first, but then started to gradually warm up. Halfway through this period life started to go extinct. The second period in the Paleozoic Era was the Ordovician Period…

Atheistic naturalism must answer many question, but their answers are not further coming, dubious at best, or based on faulty reasoning. Questions such as to why is there something rather than nothing. The laws of logic. The beauty of mathematical principles, and there applications to the world around us. The necessary fine tuning of biological information. The fine tuning of the universe and earth to support life. What about consciousness? If chance is the father of all these questions, than…

Introduction The purpose of this statement is to address the recent changes to the South Carolina Curriculum Standard. Research will be conducted on both Evolutionary theory and Intelligent Design theory to determine if high school biology teachers should teach their students Intelligent Design as a valid alternative to Evolutionary theory. Intelligent Design The Intelligent Design theory argues that the world and all the creatures in it were created not by random mutations and evolution, but…

with the breakup of one supercontinent (Pangea) ,and the formation of another. In addition, plants became common, and the first vertebrate animals populated land. The Paleozoic began with the Cambrian Period about 53 million years best known for leading in an explosion of life on Earth. This Cambrian explosion encompassed the evolution of arthropods which are ancestors of today's insects and crustaceans, as well as chordates which are animals with rudimentary spinal cords. Vertebrates are a…

alleging rare preservation and error of the fossil record. The Cambrian Explosion refers to the appearance in the fossil record of most major animals about 543 million years ago. The Cambrian Explosion is often represented as a test for evolution in light of the fact that the sudden blast of progress in the fossil record gives off an impression of being conflicted with the more common slow pace of evolutionary change. “…the Cambrian strata of rocks, vintage about 600 million years, are the…

It’s an honor that I successfully invited Plato, one of the Big Three of Greek philosophy, to Cemetery News for an interview. Editor: Mr. Plato, you used to firmly believe that there were two realms and forms only existed in the realm of forms. Forms were incorporeal, intangible and insensible while objects in our world, which was the material realm, were imperfect replica of those forms (Lindberg 13); forms are regular geometrical shapes like triangles (Lindberg 26). Now that you’ve read some…
