Theories of How Life Began on Earth

Evolution is a change in the characteristic of living organism through time. Modern synthesis, one of the greatest intellectual achievements of biology, could explain how mutations and natural selection could produced large-scale evolutionary change. There are 4 mechanisms for evolution to occur; mutation, gene flow, genetic drift and natural selection.
Although, there are a number of misconceptions about evolution; it does not explain the origins of life, it is not progressive, natural selection is not about the survival of the fittest individuals in a population, humans are not currently evolving, it does not make organism better designed nor does it gives organism what they need to survive. This essay will describe further, 3 common misconceptions

We can know the origin of our universe only if we have had experience if the origin of the worlds. (1)

This means that the system appears impossible to create by the course of naturalistic evolution, that is, many small and gradual steps that eventually form the functioning product. Evolutionary theory proponents have, so far, been unable to satisfactorily address the issue of irreducible complexity in biological systems such as the eye and the blood. Intelligent Design theorists, however, are easily able to explain the phenomenon of irreducible complexity by pointing to the existence of an intelligent being that either guided or created the first forms of life.

According to Dr. James Krupa of The University of Kentucky “evolution is the foundation upon which all biology rests.” In biology, evolution is the genetic change in characteristics over generations and is dependent on the process of natural selection. ‘The theory of evolution is based on the idea that all species are related and gradually change over time’ (Genome Campus, 2017). Genetic variation is vital to evolution as it affects the physical characteristics or phenotypes of morphology. Natural Selection is affected by environmental factors that act upon a population and result in the mutation of organism through offspring. These mutations enable individuals to adapt to their environments in order to survive, find food, avoid predators and

Every since the publication of the Origins of Species in 1859, the theory of evolution has been generally accepted by scientists around the world, that is, until 1996 when Michael Behe published his book Darwin's Black Box, calling the theory of evolution into question. The theory of evolution states that individual single point mutations in DNA give rise to the development of new characteristics in species. If these new characteristics are advantageous for survival, then the genes are passed down to new generations. As these characteristics are accumulated, new species develop. However, while most scientists have accepted evolution as a scientific fact, they have yet to answer some basic fundamental questions about the process itself. Michael Behe points to this and proposes that the reason scientists do not yet have all the answers regarding the processes behind evolution is because they have failed to see the intelligent design that lies within it. The author asserts that the "data of biochemistry argues strongly that many molecular machines in the cell could not have arisen through a step-by-step process of natural selection"¦much of the molecular machinery in the cell is irreducibly complex." (Bohlin, 2000, p. 103)

“In the beginning was the big bang,”[i] writes John Polkinghorne, a physicist turned theologian. As the reader follows through the remainder of his cosmic creation story, the reader is intrigued at how mystical and religious the story sounds. “The space boiled, in the rapid expansion of the inflation era, blowing the universe apart with incredible rapidity in the much less than 10-30 seconds that it lasted. . . . The world suddenly became transparent and a universal sea of radiation was left to continue cooling on its own . . .”[ii] Then, the story unfolds to tell of the creation of hydrogen and helium and the creation of stars. The death of stars follow, which

The universe of the past was understood to be a simple one-galaxy model that was both unchanging and immeasurable. Theories have constantly changed and been reconstructed to better portray the progression of human understanding over time. “The cosmos began

At the foundation of almost every culture there’s a creation story or myth that explains how the earth came to be. These stories have an enormous influence on people’s lives about how they think about the world and their place they are surrounded. These stories have been passed down from one generation to the other for many years. Some stories speak of birth and a supreme being who created them while others say elements formed them. Where did we came from? And how did we got here? has been one of the questions that many have asked for thousands of years. For many of us, the answer remains uncertain, while scientist says that the universe started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today (the theory of the Big Bang), other cultures and religions believes that a supreme being or God created this universe out of nothing. Despite the different beliefs, they all agree that the universe didn’t form itself.

In order to understand our place in the universe, we must understand the universe itself. Scientists, researchers, astronomers, cosmologists, physicists, amateur astronomers and a slew of other groups of individuals largely interested in the cosmos, help with discovering new and fascinating theories or proof of different phenomenon within the universe. Three scientific articles help readers to realize scientists are constantly deep in work to unravel the hidden truths. “Dark Matter in the Discovery Age”, “Why the Universe Had no Beginning”, and “What String Theory tells Us About the Universe” include theories vastly different from one another, but lead to the same conclusion; the universe’s creation.

Secular scientist believe that energy and matter exploded, and because of the explosion, or ‘big bang,’ the universe was formed. But a very prominent question appears- where did the

The formal “Theory of Evolution” thought to have come about by Charles Darwin, is built on the premise that all life is related and has descended from a common ancestor; meaning the birds and the bananas, the fishes and the flowers are all related (“Darwin’s Theory of Evolution”). In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival. This process is formally known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different

During life, you are faced with questions that have no answer, like is there life after death, or how big is the universe, or even how our world was created. The problem is, is that there is either too many answers that you’re unsure of which one is truly the answer, or everyone just stays quiet so there is actually no answers, wrong or right. Today I am going to be focusing on the last question. Over your life, have you ever asked yourself, who or what created the world? While reading this paper, you will be shown one of the many possibilities of how this world came to be.

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.

The article, “A Matter of Scale,” urges the audience to observe the small and extraordinary components of the biosphere and acknowledge its genetic variations as explained by Darwin’s theory of evolution. However, Kelly’s essay, “Evolution: An Article of Faith,” considers Darwin’s theory as a “false religion” suppressing God’s ability to create the “work of intelligence.” (Evolution) The heated debate over the credibility of Darwin’s theory of evolution has led to the division of scientific and religious groups. Devoted, religious people discover two major flaws with Darwin’s theory of evolution regarding the inaccuracies of the fossil record and the contradicting phrase “survival of the fittest” that has passed on harmful mutations to next

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.
