    Factors that lead to the Cambrian explosion and what followed Randy Cheng Cheng.801 ID#: 200357882 Factors that lead to the Cambrian explosion and what followed ID#: 57882 Introduction: The Cambrian explosion is thought of as the time where organisms on Earth started to diversify and form skeletons that could be fossilized. The development of fossils in early organisms is what gave scientists what they needed to start learning about how life really began to evolve. This event is usually described as a quick process as if the species evolved instantly within a few years. But on the contrary the duration of this incident lasted for about 25 million years (7). The cause of such an explosion during this time is still being hypothesized,…

    In the second part of the lecture, lecturer Michael N Dawson shared with us the information in his research on Jellyfish. Before he jumped into talking about this topic, he first mentioned about the formation of marine lakes. Prior attending to this lecture, I have never heard of Marine Lakes and did not have too in depth knowledge about Jellyfish. However, after I listened to what lecturer Dawson’s presentation, I think the formation of marine lake are fascinating. When see water raised,…

    1. Short summary of the history At 145 ± 4 to 66 million years (Ma) ago, Cretaceous period was the last period of the Mesozoic Era, right after Jurassic period and followed by the Paleogene period of the Cenozoic Era (International Commission Chart, 2014). 'Creta' in Latin means chalk and this is due to the large amount of calcium carbonate deposited by shells of marine animals thus resulting in large quantities of chalk (American Geological Institute, 1972). The shifting of continents as the…

    The Cambrian explosion is referred to as “Biological Big Bang” (Science News) or “Evolution’s Big Bang” (Science) (Levinton, J. S.1992), because of the unexpectedness presence of animal life in the Cambrian. Figures have it that it started back 542 million years ago and terminated approximately 40 million years later. This era is marked by the emerging of profuse skeletonized metazoans, an abrupt intensification in biodiversity and the appearance of most modern lives (Von Bloh 18). Animals that…

    Cambrian Explosion Report

    • 2 Pages

    Around 543 million years ago the Cambrian Explosion occurred, some say it may represent the most important evolutionary event in the history of life on Earth. The “Cambrian Explosion” refers to the rapid appearance of most major living animal body plans in the fossil record within 20 million years or less. This may seem to be a long period of time but is a relatively short in evolutionary history. This swift change in the fossil record appears to be inconsistent with the ideal of the slow…

    Cause of the Cambrian Explosion is an article that argues for a combination of factors that lead to the mass growth in animal population 541 million years ago. According to Smith and Harper, scientists have been proposing hypotheses on the cause of this event since the dawn of science. Hypotheses range from explosions in space to “intrinsic genomic reorganization” and many others. Most current ideas fall into three categories. They propose that, “The rapid diversification of animals in the…

    The Cambrian Period was an era filled with a massive explosion of a variety of animals and ecosystems. It was a time where super continent Pannotia no longer existed. During this time period, North America remained above water and was eroded by running water. North American was also on the equator which meant warm climate. The continents were oriented very differently, the east coast of North America faced the south. Activities such as transgression of the sea, and carbonate deposition went on…

    About 542 million years ago, an event known as 'The Cambrian Explosion' also known as 'Cambrian Radiation' occurred. It began in the Cambrian period which took place during the Paleozoic Era 542-251 million years ago. It is one of the most significant episodes in the history of life (Conway Morris, 2006). The Cambrian Explosion changed everything. Prior to the Cambrian Explosion, large animals were soft-bodied. Palaeontologists discovered fossils which accounted for approximately half of all…

    The uplift brought Cambrian Wilberns rocks to the surface, which is where almost every study of the Wilberns is located (Barnes and Bell, 1977). The Llano uplift area contains a wide swath of central Texas, from Concho County in the west, to Travis County in the east. The western Llano Uplift area contains numerous outcrops of…
