Scientific Creationism Introduction In 1859 Charles Darwin published The Origin of Species where he proposed the theory of evolution for the first time. Since this radical theory was first proposed, there has been a debate over its validity and the theological implications that come with it. In order to understand the reasons why Darwin's theory has caused so much debate over the past century it is first necessary to examine evolution and Darwin's theories about the origin of species. Evolution is, strictly speaking, simply change over time. A biological definition is, more specifically, "any change in the frequency of alleles within a gene pool from one generation to the next (1)."
Biological evolution is defined as any genetic change in a population that is inherited over several, successive generations. (R.Bailey, 2014) The changes accumulate and over time a new species is created. One of the basic mechanisms of evolution is Natural Selection. Natural Selection is random genetic variation occurring within an organisms DNA and the beneficial mutations being preserved because they aid survival. (C.Darwin, 1859) Two notable scientists associated with the theory of evolution include Charles Darwin and Jean-Baptiste Lamarck.
Their work introduced a new perspective on the study of growth or change in humanity. The center of evolutionary psychology focuses on questions like: How does a trait develop and evolve in an individual, Are all traits subject to change or are there certain unchanging human traits? By asking these sorts of questions, evolutionary psychologists, thanks to Darwin, can understand if a certain trait is shaped by natural selection and how a trait can contribute to a beings survival. In other words, the world has gained a new persp... ... middle of paper ... ... Although one hundred and fifty five years have passed since Charles Darwin’s book, On the Origin of Species was published his influence is still felt today.
Charles Darwin came up with the theory of natural selection that caught the public’s attention due to its opposing ideas from other scientists of his generation. Natural selection explained how species were able to evolve over the course of thousands and millions of years. It showed how species characteristics and physicality’s could change due to other causes such as the environment, food supply, predators and/or diseases. Darwin explains a scenario in which rabbits are split into two groups and tested on which would survive in certain circumstances. He writes, “…those individuals with the lightest forms, longest limbs and best eyesight, let the dif... ... middle of paper ... ...well as other organisms to determine the characteristics of civilizations before us.
Evolution, what is evolution? Evolution is the process by which different kinds of organisms have changed and adapted from their earlier forms. Evolution relates so closely to biology because biology is the study of life and evolution is how living organisms have adapted to the environment. My goal for this paper is to explore evolution in mammals, the basic theory of evolution, beliefs of evolution, the main contributors of evolution, evolution in humans, evolution in monkeys, things that humans lost from evolution, as well as extinctions. I became interested in this topic because it hard for me to think at one time humans had tails, or that some species of ape’s DNA is very similar to ours.
However, due to the vagaries of weather including the global cooling and the global warming, they migrated from their original habitats. Different populations moved to different habitats hence in adapting to the new habitats, the populations acquired new physical characteristics that were inherited by their progenies. Thus, different races emerged including the Whites, Indians, Dravidi... ... middle of paper ... ...ases will ensure increased longevity and improved standards of life for the future generations hence they will have distinct physical features. For instance, it is posited by evolution theorists that men will have deeper voices, square jaws, and big penises while women will have smooth hairless skin, firm breasts, and even features. In the view of the evidence of evolution in the human race, it is tenable to state that the human race is still evolving and will continue to do so even in the future.
With the studies that Charles Darwin obtained he published his first work, “The Origin of Species.” In this book he explained how for millions of years animals, and plants have evolved to better help their existence. Darwin reasoned that these living things had gradually changed over time to help themselves. The changes that he found seemed to have been during the process of reproduction. The traits which would help them survive became a dominant trait, while the weaker traits became recessive. A good example of what Darwin was trying to explain is shown in giraffes.
One of the most important principles of biology is the main idea of evolution. This theory states, “that all living organisms have evolved from a common ancestor through natural selection acting on hereditary variation” (Reece, 2011). Many people today, know humans have evolved from a common ancestor; but they do not recognize the importance of it. Everyone should be educated about how organisms evolved because humans have evolved throughout many centuries. Charles Darwin had many theories that incorporated the main principle of biology, natural selection and evolution.
Both present compelling arguments and are at odds with the other. I believe Homo sapiens were created by a millennia of small changes occurring gradually, before we get to that however let us further examine the schools of thought. Phyletic gradualism is the idea that genetic changes occur constantly and very slowly over long periods of time to produce a species. Speciation in this manner was proposed by Charles Darwin (Saylo, Escoton & Saylo, 2011). Darwin proposed that it was the process of natural selection gradually weeding the unfit from the population thus creating a new species.
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens.
