This paper discusses the theory of evolution in detail. Topics this paper will address include defining the theory of evolution and explaining how the theory has evolved over time, as well as highlighting the strengths and weaknesses of the theory and examining how effective the theory is in today’s world.
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.

Although Charles Darwin’s theory of natural selection was a marked departure from his predecessors, it was neither built alone nor stands alone. His 1859 work, The Origin of Species, grew from theory that had been advanced by naturalists before him and was in turn incorporated into genetic evolutionary theory, among others (Frisancho). Similarly, the term natural selection encompasses Darwin’s conditions for it to occur, how it is measured, and how it is related to evolution. This information can then be used to understand how it relates to humans.
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
Darwin theory, he first started talking about an organism, his theory was that in a population shows a difference in traits. The following theory was survival of the fittest, it is when one appears to look like their parents and they are comfortable in their environment, and has the possible to live longer and might reproduce being relaxed in their environment. Beneficial Traits is to increase in frequency over time in a population since individuals with traits are more likely to produce and will pass on the gene to the next generation. It is not important to be a perfect specimen, but important to produce more babies. In addition, Darwin theory was based on the
Natural selection is the notion that all forms of life have ultimately from a single common ancestor. Darwin argued about how “all the organic beings which have ever lived on this Earth have been descended from some primordial form.”
Charles Darwin revolutionized biology when he introduced The Origin of Species by Means of Natural Selection in 1859. Although Wallace had also came upon this revelation shortly before Origins was published, Darwin had long been in development of this theory. Wallace amicably relinquished the idea to Darwin, allowing him to become the first pioneer of evolution. Darwin was not driven to publish his finding, which he'd been collecting for several years before Wallace struck upon it, because he had "never come across a single [naturalist] who seemed to doubt to permanence of species" (Ridley, pp. 70). What follows are the key points of Darwin's Theory of Natural Selection taken directly from the two chapters concerning it in his book
“Death pursues the native in every place where the European sets foot,” these are the words of Charles Darwin (Tasmanian Genocide ). Darwin was a biologist who studied many plants and animals and brought forth the theory of natural selection. This theory stated that when adversity strikes a population, the strongest will survive, and the adaptations of the surviving species would be passed on to the next generation, and so on. But what this theory did not include is what happens when all of the people of a population are killed in mass murder and by brute force due to greed and racism.
Charles Darwin is the founder of Social Darwinism, as he created the theory of evolution by natural selection. Social Darwinism is the theory that people are subject to laws of natural selection.
What makes humans such a successful species is the unique skill of altering the environment around us to suit our needs. According to figure 1.4 in our books, humans started to domesticate plants and animals around 10,000 years ago. Domestication of plants and animals for our own personal use of food, clothes and labor all contributed to our cultural change from hunter-gatherers into farmers. This domestication cancels out Darwin’s Theory of natural selection, because now humans were in charge of what traits live on causing artificial selection. For example a championship horse breeder wants to breed with another championship horse in order to create a horse with amazing racing genes all around. This example works for anything humans have
The word science comes from the latin word scientia meaning knowledge, which is the condition or fact of being aware of something. Knowledge could be attained through various ways. It could be familiarity, gained through experience or learned through observation using one’s given senses. It could also be attained through cognitive reasoning, as coming to a conclusion. Consequently, the range of one knowledge varies and is tested through various types of examinations.Nevertheless, having knowledge does not mean that knowledge is true. Two individuals may observe the same thing but may come to two different conclusions., depending on their perspective. Then who is to say which one is right. That is when science comes in, it is a systematic process of examining a deduction or an infere from an observation.
According to Simon et al, evidence of evolution is apparent and has been for many decades. Fossils are one way to prove the theory of evolution. They can be found inside sedimentary rocks that are covering dead creatures. Over thousands of years these rocks form layer upon layers. These layers of rocks make up what is called a fossil record. Each layer contains creatures that lived millions of years ago. (Simon, 2015) Sometimes the fossil record does get lost in the translation due to damage. This fact makes the fossil record very intricate, but sometimes hard to
Charles Darwin came up with the theory of “Natural Selection,” which explained how animals produce offspring that will replace them. The theory of “Natural Selection” also fits the phrase “survival of the fit,” which became (or evolved - how fitting) “survival of the fittest.” Basically, animals eventually adapt to their environments through evolution. The evolved organisms, or the “fittest,” will end up surviving better and longer than those that are not as adapted.
