The Theory Of Evolution By Natural Selection Essay

Darwin’s theory of evolution was along the lines of all life being related- each descending from a common ancestor. His theory presumes the development of life from non-life and suggests purely naturistic

Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

Darwin’s Theory of Natural Selection, a scientific theory that supported the belief of evolution, was manipulated and applied to different areas of life, and thus it became the shaping force in European thought in the last half of the nineteenth century. Darwin, through observation of organisms, determined that a system of natural selection controlled the evolution of species. He found that the organisms that were most fit and assimilated to the environment would survive. They would also reproduce so that over time they would eventually dominate in numbers over the organisms with weaker characteristics. This new theory was radical and interesting to the scientific world but its effects reach far beyond this small institution of

Natural selection, together with the rules of inheritance discovered by Gregor Mendel, stand at the basis of modern evolutionary biology.

Charles Darwin includes an effective beginning for his work, Natural Selection. By introducing his theory with a set of questions, interest to continue reading is developed. One question Darwin poses is the possibility of how one can survive, taking into account the circumstances of climate and traits. An interesting concept Darwin alludes to is that some individuals possess certain traits that enable them to survive. Another method implemented in the beginning of Darwin’s piece is the broadness of the context. Darwin does not go into any specifics right away, as the reader will learn more as they continue. “Let it be borne in mind how infinitely complex and close fitting are the mutual relations of all organic beings to each other and to their physical conditions of life” (Darwin 900). Darwin accounts for how unique each organism is, but generalizes the statement by categorizing all organisms as complex. By doing this, the reader is inclined to continue

Evolution has been a very debatable topic since the theory of evolution first evolved. By definition, evolution is “the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth”, but there are many different types of “evolution” such as coevolution, divergent, parallel and convergent – all with different theories. Jean Baptiste Lamarck was a French naturalist who invented the theory of inheritance of acquired characteristics (aka. “soft inheritance”). This evolutionary theory described how the natural environment affected the way an animal used their body parts. The features used regularly or for survival are passed onto the creatures offspring, and the parts that weren’t used, weren’t. On the other hand, another English naturalist Charles Darwin established a theory of “natural selection”. A process in which creatures that survived in their environment would pass their genes through the generations, compared to the weaker species with a lower survival rate, who reproduce less offspring or none.

Darwin’s theories and discoveries caused much controversy to the world and still does today. These controversies occur more in

Charles Darwin’s experiment was not 100% accurate. His definition of mechanism of evolution was quiet accurate but two major factors were missing.

The ongoing scientific investigation of how exactly evolution occurred and continues to occur has been an argumentative idea amongst society since Darwin first articulated it over a century ago. The scientific basis of evolution accounts for happenings that are also essential concerns of religion; both religion and science focus on the origins of humans and of biological diversity. For instance, in the reading “Truth Cannot Contradict Truth,” Pope John Paul II, addressing the Pontifical Academy of Science, discussed the matter of God as creator of man. The Pope explains that men cannot relate to animals because men are superior. The reasoning for that is because God created humans under his likeness. What the church is saying about mankind

Many scientists believe variations are caused by environmental factors, such as food availability, weather and more; and that species evolve when environmental conditions change to increase the species survival. Darwin censures this idea; he believed that the main cause of variation is due to reproduction (Chapter I). Darwin suggested that parents pass down specific characteristics to their offspring, and those variations are continued on in the following generations. The problem with Darwin’s theory of reproduction is that Darwin did not comprehend how or why some characteristics are perennial and how others are not. Darwin’s inferences on variations also conflict with the idea that God created species independently, which was widely understood by many people in a time where religion was prominent (Chapter II).

In 1895 Charles Darwin published a book describing his theory of evolution, and his theory of the natural selection process. This theory caused much uproar in the religious community because Darwin’s theory went against the story of creation portrayed in the Holy Bible. His theory claimed that all life currently in place had evolved and adapted from a single organism in the beginning. Over time and by process of natural selection only the dominant species were left over while the other, less dominant species, went extinct. His theory, backed by scientific analysis, had dismissed the idea of a single deity creating all life on Earth. It is not like Darwin had a personal agenda against religion or anything,

Throughout his Abstract of the Origin of Species, Darwin invites the reader to be open minded and understanding to his ideas through Naturalist eyes. The Naturalist attempts to use nature’s laws as to the forces that function in the world. Naturalists do not use spiritual or supernatural philosophies to answer any scientific inquiries or to answer any behaviors of the universe. Specifically in the Origin of Species, Darwin notes how: “Naturalists continually refer to external conditions, such as climate, food, etc., as the only possible cause of variation”(OoS,Abstrct). This rhetoric introduces how the variations under nature and variations through man-kind’s domestication expresses a natural selection of organisms. Through this natural selection, there is a struggle to survive with the variety of “great mutations in the forms of life”(Oos,Chptr10.). Life has shown to express completely different expressions of DNA within a species; to further import, Darwin brands nature as an Animal Kingdom that contains forms of life that change haphazardly. How do these variations come about? Conclusively, there are countless variables in which our organic tree becomes suspect to influence. Geological location, habits, Instincts and Genetic structure are a few of these

“As a world view, Darwinism cannot of course be refuted, since Faith is, always has been, and always will be, stronger than facts. “ - Francis P. Yockey

Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for
