Essay on Charles Darwin's Theory of Evolution by Natural Selection

Radiometric dating is a technique that utilizes unstable isotopes of natural elements. Because these unstable isotopes eventually decay at a constant and singular rate despite any environmental changes such as temperature or moisture changes. The unit used as measurement is a half-life which is the amount of time it takes 50% of the original isotope to decay into the next isotope or daughter isotope. Basically the amount of half-lives is multiplied by the length of the half-life to estimate the age of the object being tested. Every element used has a different half-life and that makes each useful for measuring certain types of material. Some have longer a half-life and thus a longer effective dating range. Potassium-argon dating is useful for dating material that is extremely old. This method is used by geologists to replace relative ages based on rock formation with absolute ages. The dates found from the radiometric technique are accurate because the sources, the individual radioactive isotopes, are unchanging and unaffected by environmental factors. This means that the radiometric data will always be precise unlike relative dating which relies on the theory of uniformitarianism, the theory that geological history is made up of endless and uniform

The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a "warm warm little pond" and that it took billions of years for the present diversity of living things to evolve. At the time, it was thought that the few "missing links" in the fossil record would be soon filled.(Darwin, 1927 ). Today, however, there is today a considerable body of scientific evidence that refutes this entire theory.

“The Origins of Species” by Charles Darwin proves to be one of the most influential and impactful books of all time. This book changed the way people viewed man, evolution, and religion because it is about Darwinism, Charles Darwin’s theory of biological evolution. To get more into detail, Darwinism explains that

Fossilization is the process where bones evolve into fossils and preserve in different environments that help to sustain ossein. Some environments include permafrost, amber, peat, dry air, or within sedimentary rocks. There are several different ways that fossils can be classified; this includes original, replacement, carbon film, and indirect fossils. ‘Original fossils for when part of the organism is preserved, with chemical composition being about the same as it was when it was living’ (Pearson Science, 2018). ‘A replacement fossil forms when a part of the organism is chemically changed into another mineral. Replacement fossils commonly form when the calcium carbonate found in shells and bony skeletons turn into another mineral such as silica, also called silicon dioxide’ (Pearson Science,

In his own time, Charles Darwin was a controversial figure, and although long ago, that same controversy sparks today in the twenty first century. There were many who loved and many who hated Darwin, which has allowed the controversy to expand in recent years to include questions about his role in the development of the evolution theory. The theory of evolution was not created by Charles Darwin; however, through his On the Origin of Species, he logically expressed the theory which ultimately shifted the burden of proof from those who denied it to the supporters of evolution all of which was corroborated by careful observation.

Over one hundred fifty years after Darwin’s theory has been published, the evolution theory is still highly controversial. The idea didn’t go well with the public, Darwin was so embarrassed by the ridicule he received that the swimming-bear passage was removed from later editions of the book (Than). Darwin’s views brought him into fierce conflicts with others who continue to maintain that the account of divine creation contacted within the Bible was correct. According to Than, Darwin’s theory of evolution by natural selection is one of

Every living thing on Earth has evolved into its current form over the course of millions of years. The theory of evolution explains how these organisms changed over time through natural selection. Evolution is still controversial within our society because it conflicts with religious beliefs on how life on earth formed.

Throughout history, there has been a major debate on the theory of evolution. Is it true? The term evolution has been defined many ways, and for the purpose of this paper, I will use the fourth definition from the Merriam-Webster dictionary. “Evolution is the descent with modification from preexisting species: cumulative inherited change in a population of organisms through time leading to the appearance of new forms: the process by which new species or populations of living things develop from preexisting forms through successive generations.” (Merriam-Webster, 2017) What does this mean and how could it possibly be true? In this paper, I will explain the different ideas

“It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.” Charles Darwin's theory of evolution by natural selection remains one of the best known theories in science today. However, The Origin of Species had a significant impact on society when it was published in the late 19th century. The idea of evolution and natural selection uprooted many popular ideas at the time and led to the creation of new movements. Charles Darwin's theory of natural selection impacted 19th century society in a scientific perspective, a sociological perspective through the rise of social Darwinism, and a theological perspective in the debate between evolution and creationism.

The evolution theory, one of the most significant theories, laid groundwork for the study of modern biological science. This theory has lead scientists into unending debates due to lack of empirical supports. Until the mid-eighteenth century, when Charles Darwin came up with an explanation to evolution, scientists, then, began to endorse this hypothesis. In “Natural Selection,” Darwin explains the natural selection, a plausible mechanism that causes evolution, to gain approval of his cynical audience for his evolution theory. He supports his claim with numerous examples of animals and plants that have developed traits beneficial for survival. A century later, Stephen Jay Gould, influenced by Darwin’s work, supports the evolution theory

Charles Darwin's theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that weren't best suited died off and didn't get the chance to reproduce.

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival.

During the time when Charles Darwin was alive (1809-1882) most of the Western culture believed that the world was created by God and only several thousand years old. They believed that our world was always like it was then. So when Darwin wrote The Origin of Species it shook up both the cultural and scientific views of his time. His views that evolution occurs by natural selection was one of the most radial theories during his time, yet today is widely accepted as a fact among most of the world.

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

Before the theory of evolution was a widespread theory in the world of science, Greek and Roman philosophers had their own theories about how life came to its present state and where it was going from there. One theory at the time was that all organisms are reflections of a “perfect” form and were coming closer to it all the time, although this was the less accepted theory even though it was closer to the truth proven hundreds of years after, while another was that all things were simply places on Earth in their present form, common to modern day Creationism. Even after this, Darwin was not the first to try explain evolution, he just provided convincing proof and published his ideas. The publishing of Darwin’s Theory of Evolution was
