The Cambrian Explosion: Biology's Big Bang

Improved Essays
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, many scientists all over the world have different theories and ideas on what actually enabled so many different creatures to appear out of basically nowhere at such a rapid pace. The First theory was that there was an immense growth of oxygen level in the ocean these animals started developing in. The second theory was that there was a development of vision, eye spots, during the Cambrian period. Eye spots where traits that active animals developed to easily spot their pray. The theories allow the reader to draw conclusions and enables the reader to speculate over what the cause of the Cambrian Explosion actually was. …show more content…
Before the Cambrian period, there was such low amount of oxygen for active animals to survive. During the Cambrian period there was a rapid increase of oxygen in the water which is believed to be the direct result of the phenomenon called the snow ball earth During the long period of recurring ice ages. When the glaciers would melt, rocks were exposed and eroded, which then poured nutrients in the water causing photosynthetic algae and later causing oxygen levels to rise. After the increase of oxygen levels, many active organisms where able to survive and increase rapidly and diversify in so many different

    Abstract: My research paper is covering the different theories covering the origins of life. Primordial Soup: The primordial soup theory says that life began in a lake or ocean as a combination of chemicals created amino acids, and from there life evolved. A Russian chemist named A.I. oprin and an English geneticist named J.B.S. Haldane came up with this theory in 1920. to test this theory they collected and mixed elements thought to be on earth at the time and sparked the mixture with electricity, The experiment resulted in the creation of amino acids.…

    There are many theories for how life started on earth. After reading many theories, I found the Lighting and Panspermia theory the most interesting. These two theories made the most sense to me even though they don’t have much in common. The Lighting theory is the idea of chemicals from earth’s early atmosphere working together with chemicals and lighting from erupting volcanoes in order to create the first life on earth. The second theory is the Panspermia theory, the idea that earth’s first life dame from outer space.…

    Introduction: After the extinction of some species, first vertebrate animals have appeared on the land. These animals are fishes which were appeared in the earliest of Paleozoic era specifically in Cambrian (jawless fish fossil). The evidence of this appearance was finding fossils in sedimentary rocks such as limestone, shale, sandstone and etc. Millions years later, different type of fishes have appeared after the jawless fish, which are fishes with jaw. Later on ray finned fishes appeared and evolved into amphibians and finally to reptiles.…

    Most of these hypotheses have been posited as stand-alone processes that were the main cause of the explosion, yet many of them are tightly interlinked and codependent. The rapid diversification of animals in the early Cambrian is likely to have been the result of a complex interplay of biotic and abiotic processes.” As you can see, there’s not a specific conclusion to the exact cause of the…

    When retreatment of glaciers happened, a change of life was earned for many organisms. Particulary, the post post-glacial period proved vital for evolution, as it is said that huge complex multicellular organisms appeared when the temperatures were rising proving that the environment was favorable for evolution. As for the developmental evidence, scientists say that the environment never had nothing unique during the Precambrian-Cambrian transition, and it was a necessity for evolution to happen for diverse and new body plans to emerge. In animals, developmental genes are the ones responsible in…

    At the end of this period, around 360 million years back, backwoods of greeneries and asparagus like plants secured a significant part of the Earth's surface. This plenitude of vegetation prompted a vital advancement. In the oceans, there was exceptional rivalry for nourishment among the various sorts of fish. Ashore, be that as it may, there was no opposition for nourishment in light of the fact that there were no area creatures. Researchers feel that transformations, or hereditary changes, step by step permitted certain sorts of fishlike animals to invest brief times of energy out of water, rummaging for plant nourishment ashore.…

    The Big Bang is how humans nowadays believe the earth was created based on scientific experiments and theories. The theory states that a singularity was created, which is a zone that defies our understanding of physics (The Big Bang Theory - An Overview, 2015). Eventually this expanded creating a viable universe for life. The universe is constantly expanding creating new stars and other spatial objects that are needed in the universe. Tiny micro organisms formed on Earth that over millions of years started to evolve and became more complex.…
