Name: Lyn Part I: Write a thesis statement (according to the guidelines I have given you in class) for an essay that answers the following question: What is the author trying to convince you to believe by reading this book, and what strategies does he/she use to persuade you? Thesis statement: Human were not created by God. They developed or evolved from simpler organisms because physical evidences like limestone and fossils, scientific proof of DNA, and remaining animals such as finches and iguana that show environments effect. Part II: Give three categories of evidence to examples to back up your claim, with 2 examples for each category. I. If the creation story of the Bible is true, mankind would only be about six thousand years old. …show more content…
Dinosaur extinct 105 million years after Jurassic period. By the Eocene, 50 million years ago, the climate had grown cooler and drier, so animals like tapirs had appeared. In the last million years ago, during the extreme cold of the Pleistocene period, Mammoths were common and roamed throughout Western Europe. II. If all human living today descended from the single couple, Adam and Eve, how do you explain the large differences between the peoples of the earth in such a short period of time? Gregor Mendel showed that he could cross pollinate pea plants (mis their genes) and produce offspring with different characteristics. These pea plants have really short life cycle, for the descends of Adam and Eve to become as varied as humans are today. There would need to be some genetic variation introduced into the process. Also because humans have a longer life cycle than pea plants, it would take a much greater time than 6000 years to produce the changes we see today. If the creation story is correct, then the offspring of Adam and Eve would have had to breed with each other and the next generation likewise. Today we know that inbreeding causes genetic abnormalities which shows that the Bible story is
Over the last few hundred years, more and more has been added to the world’s fossil collection, fossils from all over the world. New theories have been created and old theories have almost been proven about the evolution of man. For example, we have proof that different species of man existed with certain types of DNA sequences and instincts, some we may not have anymore, or some that other species did not have back then. Even though it is subjected to much debate, one of the most widely accepted theories however, is that Homo sapiens interbred with the slightly more primitive species of man, the Neanderthal.

Then, in the preceding section, Rachels, tries to validate the existence of God by using several types of arguments such as Argument from design, Evolution and Intelligent
Around 1.8 million years ago, two hominids were born, first the Homo Erectus and then the Neanderthals. Although the two very different humans. However, were they that different? Our ancestors were very versatile hominids. They lived in various places and lived in a variety of ways. The Homo Erectus and Neanderthals were all special in their ways. They had similarities and differences that set them apart. They had similarities, but in the same way, their differences helped them survive if they had not adapted to how they lived they would have lasted the same time that their ancestors have lived. The Neanderthals lived for an average lifespan 30 years. They had to have some mistake that decreased their lifespan because if the Homo Erectus had done the same, there’s a chance that we might not be here now. Their differences set the future that we live in today. These
Fossil records from 12,000 years ago show the appearance of the Large Mammals followed by Paleoindian in Eastern North America. Another piece of the fossil record shows that the appearance of Paleoindian brought about the disappearance of the large mammals. Some people feel that, "there is evidence to suggest that rapacious hunting practice of the paleohunters in North and South America 12,000 years ago may have caused…The demise of the very animals they hunted" (Powell 1987). The evidence Powell suggests is that the extinction of a large mammal is usually followed by the appearance of humans in the fossil record. This coincidence is not only seen in the fossil records of North and South America but Europe and Asia as well. Powell shows that as human populations increased local extinctions of large mammals occurred. This was probably due to the fact that there were not many predators that could hunt the large mammals except man. For this reason it is also highly like likely that man and large mammals did not co-evolve which ultimately resulted in the extinction of large mammals.
The human archaeological record is a long and undefined story that may be the most complex question researched today. One of the big questions in human history is the disappearance of the Neanderthal people from the archaeological record around 30,000 BP. While for thousands of years Neanderthals and Anatomically modern humans crossed paths and perhaps lived in close relations, we have yet to really understand the degree to which they lived together. My hypothesis is that these two hominids, Neanderthals and Anatomically Modern Humans, interbred exchanging genes after Modern Humans dispersed from Africa and creating like cultures and material remains. The differences between Neanderthal and Modern humans are not only physical but also genetically evolved and this research will determine an estimated amount of admixture between the two groups.
An argument is defined as presenting reasons for a conclusion in order to convince an audience of a certain point of view and an explanation as a clarification of why something has happened. An argument contains some form of an opinion while an explanation holds only facts, this does not mean that a well-constructed argument is not without facts. The second piece, Lisa Fullam’s, Of God and the Case for Unintelligent Design is evidently the argument. The title itself, “unintelligent design” proves this reasoning, she provides facts/reasoning for her audience to believe that the notion of intelligent design is unintelligent in and of itself because nature has too many flaws. Fullam provides facts about rabbit digestion, horse digestion, mammalian testicles, and human back ache followed by her opinions. First, to Elizabeth Bumiller, who doesn’t take a side while providing facts for each side, Fullam feelings strong about her opinions, her sarcastic questions help the audience tap
There is evidence to suggest that Homo neanderthalensis and Homo sapiens had coexisted for approximately 35-40,000 years, (Fagan 2010) from around 60,000 years ago to 25,000 years ago when they finally went extinct (Gibbon 2001). Anthropologists are still uncertain what the cause of their extinction was. This paper will analyze three main theories of Neanderthal extinction. The first theory is the competition theory, which claims that the Homo sapiens and Neanderthals had to compete for resources, ultimately leading to their demise. The second theory I will discuss is the climate change theory, which claims that Homo sapiens lived while Neanderthals died because they were better adapted to the climate. The last theory I will discuss is the possible “extinction through absorption” theory which claims the Neanderthal interbred with the Homo sapiens and became one species. In this paper I will also be comparing the technologies, and diets of both species. In addition, I will look at the anatomic relation between the Neanderthals and Homo sapiens, how their body shape and size differed, and if this gave any advantage to one side or the other. My thesis for this paper will state that Homo sapiens and Homo neanderthalensis had co-existed but the disappearance of the Neanderthal in Eurasia is due to the appearance of the more culturally advanced and genetically superior Homo sapiens and the failure of the Neanderthal to adapt in an evolving climate.
Our technology is not yet strong enough to rule out both sexes as carriers of common genes. Therefore, the case of interbreeding still remains to be closed. However, Paabo and his team are confident that their research has proved that Neanderthals could not have died out solely because of interbreeding. Scientists are still trying to conclude what exactly the Neanderthals did; this discovery brings them one step closer, but not completely to the edge.

A Genetic Odyssey’ is an interesting movie to watch. There were many thoughts that passed my mind as I watched the movie. First of all, it was interesting to visualize the movie back in the day, assuming how one single man lived in Africa approximately sixty thousand years ago. It is quite amazing to have traced the records so far behind to find that Adam could be the father of homo sapiens after all. The better question arises when there are different sizes, races and shapes to each human being.

“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
Nearly, six million years ago, humans evolved from apelike ancestors. Today, Genetic Engineering has tried to modify the DNA and evolve a superior human race, devoid of disease, increased life span and much more resilient and robust than before.
In this essay I discuss why there is proof that there is a supernatural being known as God, who has created everything we know and experience.
