The Origin Of Life Terrestrial Or Extraterrestrial Essay

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration such as how close the planet is to its star (in the case of our solar system, the sun), how long the water and organic materials existed there, and the size and mass of the planet. One must not confuse habitable with inhabited. The term

Describe the important chemistry of early earth and how this may have given rise to life forms.

The study of science is defined as that which deals with the workings of the physical world we are able to observe and measure. The origin of life, however, is a topic that science has long grappled with, despite the impossibility of observing or proving any origins theory in a strictly scientific manner. Today, the widely accepted theory of life’s beginning is the theory of Evolution by mutation and natural selection, or Neo-Darwinism. Most people in our modern society accept this theory at face value because it is popular with the majority of scientists, but it must always be taken into account that our origins cannot be proven scientifically and that, in fact, the theory of Evolution is not the only or even the most logical theory

Ever since the origin of Earth was found, this question has wandered in the air. What will happen when Earth becomes uninhabitable? Scientists have turned to the next closest planet to Earth, Mars. There have been signs in the past of life on Mars. Many think that space exploration could be a reality. On the other hand, many think that the thought itself is unreasonable. Despite the sheet of ice found on Mars (Source D) and the possibility of extremophiles surviving in harsh conditions, the possibility of life on Mars is, indeed, a fantasy. The environment on Mars is too harsh to live in, there have been no signs of life on

Stephen Jay Gould in his article "The Evolution Of Life On Earth" aims to clarify the misconception of natural selection as the sole reason for evolution. Yet, he emphasizes on the presence of other causes and the complex unforeseeable nature of the universe that can not be explained in one theory. Even though the article is concerned with a deep scientific subject and factual information, we see the usage of description in every sentence. Description has an intrinsic role in this article where the uniqueness and the beauty of the language relies on the strong descriptive construction. It employs the power of the language and the readers senses to bring life to the subject. It also simplifies it by liking the described setting or object to something else that the readers are easily able to visualize and associate in their minds. In addition, using specific descriptive words make a statement more dynamic and effectual to the readers convincing them and inviting them to see the situation from the author perspective.( to help convince the reader and strengthen the argument of the author). It could exaggerate the details to effect the readers in a more emotional way and capture their attention. This won 't only engage the targeted audience, but it will allure other readers as well.

Chemical evolution is the main exploratory clarification for the birthplace of life. Like every scientific theory, the hypothesis of chemical evolution has an example part that makes a case about the common world and a procedure segment that clarifies that patter. The example part is that notwithstanding little atoms, complex carbon-containing substances exist and are needed forever. The procedure part is that in Earths early history, straightforward concoction mixes consolidated to frame more mind boggling carbon-containing substances before the advancement of life. The hypothesis keeps up that inputs of vitality prompted the development of progressively complex carbon-containing substances, coming full circle in an intensify that could recreate

Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found, communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect. Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.

The title of my paper is called, “Life on Another Planet.” The purpose of my essay is to explore the question of do aliens exist? I explained the possibilities that there could be other life out there in space. My conclusion was that in the future scientists could discover a planet where we can move to and live in, and even meet new species of life. As a result, scientists should develop more tools

The discovery of water in the Orion Nebula will undoubtedly provide the basis for further study. More specifically, it will prompt scientists to search for water in other regions of space at different stages of star formation. Then, if water is present in each, it may suggest that "the oceans of Earth are older than even the planet that now contains them." 7

The reigning question that ponders the minds of many individuals is “How did all life on Earth Begin”? A simple question, yet it exceeds all possibilities of theorized responses. Biologist, Charles Darwin conducted the Theory of Evolution, in which he states that all life on Earth has a common ancestor and has descended with modification through the process of natural selection. Natural selection occurs when two mates produce offspring, and through this process many subdividers are introduced, such as sexual selection, genetic drift, gene flow, and mutations that each affect the size of a species population.

Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started.

This essay is a compilation of numerous hypothesis’ of how life on Earth began. The six hypotheses’ are: Primordial Soup, Iron Sulfur, Deep Sea Vent, RNA World, Community Clay, Panspermia. Primordial Soup was suggested by two scientist Alexander Oparin and J.B.S. Iron Sulfur was proposed by Gunter Wachtershauser. Deep Sea Vent was proposed by scientists Nick Lane and Bill Martin. RNA World was brought forth by scientists Sidney Altman and Thomas Cech.

Life has continually perplexed and fascinated individuals since the dawn of mankind. The subject’s complexity is so great even over the course of human existence only a minute fraction of its mysteries have been unraveled. A phenomenon which has always intrigued scientists is the origin of life on Earth, and in recent years significant advancements have been made in the understanding of this enigma. This essay will briefly outline two theories regarding life’s origin on Earth to further comprehend why an explanation for this phenomenon has been so difficult to reach.

According to astronomical research and geological evidence, scientist indicate the universe is approximately thirteen thousand eight hundred and twenty billion years old. The first link to humanity started with a primate group called Ardipithecus. While our ancestors have been around for about six million years, the modern form of humans only evolved about two hundred thousand years ago. The age of the Earth is estimated about four point fifty four billion years because that is the age of the oldest rocks with fossil evidence of life on earth. The oldest rocks on Earth found to date are the Acasta Gneisses in northwestern Canada near the Great Slave Lake, which are four point three billion years old. The study of the origin of life on Earth, more specifically abiogenesis, is the natural process of life arising from non-living matter. Life on Earth is believed to have began from organic compounds about three point eight to four billion years ago. Despite several competing theories for how life arose on Earth scientist only know when life first appeared on Earth and are still far from answering how it appeared. Since it is hard to prove or disprove them, no fully accepted theories of the origin of life exists.

One of the main theories is that life started by chemical means in a rock where water, methane, ammonia and hydrogen were all present then with the added effect of lightening simple organic molecules formed the building blocks of life. There was an experiment that was conducted in 1953 by Miller and Urey that supports that the conditions above could stimulate organic compounds to form. *copied “ The Miller-Urey experiment attempts to recreate the chemical conditions of the primitive Earth in the laboratory, and synthesized some of the building blocks of life.
