Cambrian explosion

What is the Cambrian Explosion? You might have heard the term Cambrian Explosion from your recent science class lecture. Or you may have never even heard of it before. The Cambrian Explosion is a historical event that occurred more than 545 millions of years ago below the Earth’s surface on the very bottom of the ocean floor. This so-called “explosion” did’t happen like most explosions you would imagine. Instead, it happened slowly rather than an instant. This event got it’s name because of the diversity it formed in a relatively short amount of time.Before the event, the only organisms living on the planet were simple organisms under the sea. After the Cambrian Explosion the period is considered as the Cambrian period.…

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…

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 explosion was an event that occurred based on two different theories developed by scientists. This event was basically the development of an immense amount of animals that developed below the surface of the water. Which ended up being the reason behind the diversity of all the different animals that are now roaming the earth. This event was referred to as biology’s big bang because there was no actual concrete evidence of what really caused the Cambrian explosion to occur. However,…

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…

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…

that killed four and wounded thirty-two others. In December 2007, four lives were lost and many other where changed when an explosion occurred at the Jacksonville Florida plant at T2 Laboratories, Inc. T2 was producing methylcyclopentadienyl manganese tricarbonyl, which is a gasoline additive. The explosion caused T2 Laboratories to become destroyed and also caused damage to other businesses in the area causing windows to burst and throw…

#27 Erick Roque The Exploding Lunch Bag Introduction “POP!” A balloon just blew up. But no, it was a plastic bag. But no one was there. So who blew it up? It turns out that it blew up by a mixture of vinegar, baking soda, and… WATER!!! What do you think, can you pop a bag with that mixture? Purpose The reason why I chose this experiment is because I have seen the reaction when both vinegar and baking soda go together… an explosion of vinegar. And if vinegar and baking soda can…
