Your Inner Fish by Neil Shubin Chapter Questions Chapter 1 – Finding Your Inner Fish 1. Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004. The author and his colleagues chose to focus on 375 Million Years as it was a period when the transformation took place from fish to fish with limb.…
Each characteristics of species defines their lifestyle. From Australopithecus afarensis having canine tooth projected beyond the chewing surface and having canine diastema depicts the possibility of species having raw carnivorous food. Throughout time, species started exploring more food and started cooking leading to large molars to chew their food. The width of the dental arcade helped later species. The skull and vertebral attachment shows how species evolved to have a bipedal lifestyle.…
Which is probably why in the movie “Jurassic Park” it is named after this period. Small mammals were also present during this time period as…
Never have humans had such abundance of information, easily accessible at the touch of a finger. Philosophers, doctors and scientists throughout history have labored their entire lives to study the science of earth, space and life on our planet. Now, with the amazing technological advances we’ve experienced in the last several decades, so many monumental discoveries have shed light on these fields, answering many questions and creating many more. The question now facing many of us in our quest for knowledge is what information is credible. What makes for “good science”?…
This may suggest that they did not eat meat at all, and strictly used the animals to preserve and nourish their…
Over 250 Million years ago an unexpected events happen that made the planet earth to transform radically. This event is known as the Permian Triassic Mass Extinction or also called by many the Great Dying. This mass extinction is known as the worst extinction comparing them to the Ordovician, Devonian and the Cretaceous Extinction. Some individuals are not award that the Permian –Triassic are two forming boundary between the end of the Permian and the beginning of the Triassic period. The Permian-Triassic Extinction almost killed the whole Earth.…
I'm going to talk about the geologic evidence of the permian triassic extinction. This is a volcanic scenario. There are different geologic reasons for the permian triassic i'm going to tell you about them . During this period there has been documented changes in the air. The atmosphere went evey high which means high levels oxygen was about 30%.…
The Permian Mass Extinction Introduction There are five major extinctions in history: the Late Devonian, the Ordovician-Silurian, the Permian-Triassic, the Triassic-Jurassic, and the Cretaceous-Tertiary. Known as the Big Five, these extinctions exceeded all others in size and destruction, each killing more than 60% of species from that period. Each one acted as a bottleneck, allowing the survival of only a fraction of the organisms that had been thriving before, from which evolution and life must continue. There was one mass extinction above all that came perilously close to turning the Earth into a lifeless and desolate wasteland.…
Evaluative Analysis for Dinosaur Extinction In Stephen Jay Gould’s article, “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” Gould begins to analyze the difference between science and speculation. In the article, Gould presents that science is considered allowing humans to be able to know and gain knowledge. In “Sex, Drugs, Disasters and the Extinction of Dinosaurs,” Gould begins to state the question of why dinosaurs became extinct and what possible causes could relate to the non-existence of the dinosaurs. The first theory that Gould contemplated for the extinction of dinosaurs could be caused by the sex hypothesis. Gould believed that this theory caused the non-existence of dinosaurs because testes can only perform in certain conditions.…
The Permian was a time of great changes. It was the last period of the Paleozoic Era. It lasted from 299 to 251 million years ago. After the Permian period life on earth was never the same. By the close of the Permian period, a mass extinction happened in which a large number of earth’s species became extinct.…
1. The three schools of thought Philip Q. Yang mentions in his book are Primordialism, constructionism, and instrumentalism. Primordialism is the belief an ethnic identity or affiliation is fixed and biologically defined. For instance, some people have the false belief African Americans are inferior to White Americans, or different races having biological advantages in certain sports.…
The Significance of Nature There many meaning implied to the term nature. In many cultures nature to is referred to as freedom, a place where one can escape from the world and step into a new world filled of natural beauty. In Orwell’s novel 1984 you would think of the society of Oceania as anything but beautiful, with a dictator government, surveillance all around, and yet the term nature is still very much implied. In 1984, there are many significances to the word nature including- the symbolizing of freedom, the symbolization of beauty and it shows the destruction of the laws of nature. To begin with, Orwell shows how Winston’s time beyond the city and being emerged in nature is a symbol of freedom.…
In the essay, “Evolution as Fact and Theory,” Stephen Gould defenses Charles Darwin’s theory of Evolution over the beliefs of creationist on God creating all organisms in the world. To further his support, he states his three arguments which are observational evidence, the imperfection of nature, and transitions found in fossil records to demonstrate that even though evolution is just a theory, there are plentiful evidence of facts that supports it. The essay was not just about justifying the theory of evolution to the creationist but also to reject the ideas of blindfolded views on scientific creationism. Throughout the essay, Gould acknowledges many of the major perspectives of the scientific world to support the theory of evolution that…
The subject of evolution is widely debated topic. However there is a wide variety of evidence that supports evolution. By studying the fossil record, comparative anatomy, genetics and natural selection scientists have been able to support Charles Darwin’s theory (evolution). This report will focus on evidence from the fossil record as well as genetics.…
We know what life is. However, we do not know where life came from. Many extraordinary and intellectual people have come up with the most reasonable theories of how “life” came to be. From life being found on different planets, to life being found intriguing places of our very Earth. The Primordial Soup Hypothesis was a theory created by Alexander Oparin and Haldane in 1920.…
