Cambrian

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…

teeth will remain because it has already been layered with minerals which will preserve it. Extinction is based on shallow marine shells. All of the marine wheel look very different, and can be broken up into different categories. Specifically the Cambrian Burgess Shale is a marine animal which is preserved by minerals. Therefore when it does eventually die, there would be evidence left behind.The beeches Trilobites Ordovician bed 4 centimeters thick is 4 centimeters thick and grows towards the…

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…

earliest part of earth's history, up to 3 billion years ago. They are among the oldest rocks in the world. During the Precambrian, the Torridonian sandstones and the Moine were also laid down. Further sedimentary deposits were formed through the Cambrian period, some of which metamorphosed into the…

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…

Earth has experienced variations in climate throughout history. Several cycles of glacial advance and retreat (specifically the Permian, Carboniferous, Cambrian and Pre-cambrian glaciations) demonstrate natural climate fluctuation. These fluctuations can be attributed to deviations in the Earth 's orbit; the amount of solar energy received by Earth differing as a result of this. Current temperature trends display an aberrant rate of increase in global lower-atmospheric temperatures. This…

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…

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…

INTRODUCTION In this report, I present a summary of five major arthropod groups. The three groups chosen for this report are Trilobitomorpha, Crustacea and Insecta. Like my previous report, I have organized this report to provide a general summary of these groups, and also to examine a number of fossil specimens belonging to each group. For each group, ten specimens belonging to a specific sub-group (and a specific stratigraphic range when possible) were selected from the GB3D Type Fossils…
