The Theory Of Evolution By Natural Selection

Charles Darwin’s theory of evolution has been a topic of controversy since it was promulgated in the late 1800s. Nonetheless, its tenets remain strong, with many modern day scientists making discoveries that support Darwin’s theories of evolution, natural selection, and survival of the fittest.

The theory of evolution sets forth an explanation of how all of the living species on Earth came to be. The theory as we know it today, written by Charles Darwin, states that all the living species of today – humans included – evolved over time; we can see evidence of their evolution in the fossils of now-extinct species. In his book Origin of Species, published in 1859, Charles Darwin wrote that species evolve over time through a mechanism known as “natural selection.” Basically, each species is born with a multitude of traits, some more favorable to survival than others. Because some traits encourage survival more so than others, the animals equipped with those traits tend to breed more than the animals that lack those traits. Over time, more and more offspring are born with these favorable traits and less are born without them; thus, the species evolves. In his 1871 book, The Descent of Man and Selection in Relation to Sex, Darwin surmised that where humans are concerned, natural selection helped humans evolve in addition to a concept known as “sex selection.” Similar to natural selection, sex selection is the process by

Darwin’s first theory of evolution first formulated in 1859, by which the organisms changed over time as a result of changes in heritable physical or behaviour traits. Changes allows the organism to better adapt to its environment will help it survive

In order to understand evolution and natural selection you have got to know where it came from and how it came to be. First, let’s go all the way back to two of the four most commonly known, and most important, natural historians that encouraged the belief of an evolutionary process. Georges Buffon was a French naturalist during the 1700s. He was one of the first to reject the idea of a 6000 year old Earth. Instead, he believed it had to be much older. Buffon also proposed the idea that species did not arise separately, but rather shared common ancestors. Jean-Baptiste Lamarck, who was also a French naturalist, did not think that species became extinct, but that they evolved into different forms. He thought that changes in the environment triggered this evolving into different forms and that the evolving into different forms caused either a greater use or disuse of a structure. Both of these

Life is evolution. Humans continuously try to keep up with the latest trends in an attempt to remain relevant in society. In the past ten years, humans have evolved immensely with the introduction, development, and integration of technology into their culture. Virtually everything can be found on the internet. Pictures and documents are being shared through cloud storage rather than being shared directly with a physical document, and doing homework online is now the norm. People have adapted to the new age, and those who have not adapted are being left behind--this is where the theory of natural selection meets modern cognitive science. Steven Pinker, the author of How The Mind Works, argues that the concept of natural selection is not as linear as society may think it is with today’s information. There is more to evolution than straightforward “survival of the fittest”. Using his background knowledge in cognitive science and the social sciences, Pinker links the biological approach to evolution with his cognitive science approach in an attempt to generate a new perspective to the theory of evolution. Steven Pinker supports his claim that the concept of natural selection is more than a simple biological adaptation, but rather a combination between biological adaptation and an adaptation to the “cognitive niche”, with historical observations, analogical evidence, and exploitation of archaeological evidence.

Natural selection is most often used in the area of the natural sciences, but can apply to other fields. The knowledge question, how does knowledge develop over time? will be explored within the context of history and the natural sciences. Natural selection will be defined, in the context of this investigation as, knowledge progresses as evidence is discovered and verified. Thus the theories that have persisted in a particular subject are the most accurate ones, supported by plentiful evidence.

Extant polar bears and brown bears are morphologically and genetically different species although with new mitochondrial DNA and fossil records and the ability to understand these findings it is evident that polar bears are a lineage of the Brown Bear (Ursus Arctos). Research indicates that polar bears evolved from the ancestral brown bear, and in this paper, I will discuss the history and discovery of polar bear evolution and how it will affect polar bears for the future with implications of climate change.

evolution is based on a mechanism that he titled natural selection. Natural selection is, as defined by Darwin in his book On the Origin of Species, the method of being naturally selected for a better chance of survival in an environment. Evolution itself is the process by which organisms develop and adapt over generations.

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.

According to history, Charles Darwin is the first scientist to frame the theory of evolution by natural selection. It was publish in his book title "On the Origin of Species 1859”. Darwin express the theory of evolution by natural selection as a process by which species change over a period of time. This change take place because of the changes in genetic and behavioral traits. The ability of the organisms to change over time or adjust to fit environmental factors is due to the ancestral trait. The evolutional theory was supported by great body of evidence from various scientific disciplines.

Charles Darwin was the creator of Darwinism which is, “the theory of evolution by natural selection” (Junker 1). In school we are often taught that natural selection is survival of the fittest or the strongest wins. What seems to be a simple topic is actually one of the leading theories on the side of evolution in the highly controversial debate on Darwinism vs. Creationism. Darwinism states that certain genes in a population change through individuals. These “strong” genes are then produced more and are better able to survive making them the fittest. According to natural selection this process of evolving “usually takes place over many years, but in fast-breeding organisms it can occur rapidly, for example the spread of antibiotic resistance in some bacteria” ("Natural Selection” 1).

In “Lecture 2B- What is Evolution? Darwin’s Theory of Natural Selection” the traits or characteristics that he talks about are ones that are the features of “design”. The traits must be heritable features, have a functional fit for the specie, as well as make it a worth wile characteristic advancement for the species survival and growth.

A theory discovered by Charles Darwin, and released to the public in 1859, answered many questions for scientists who weren’t able to figure it out. Using the Theory of Natural Selection, he came up with the Theory of Evolution. In the Evolution theory, it states the genes that allow a species to thrive are passed down from parent to offspring and it also provides us with an insight of the changes an organism goes through over time, in which it relies on Natural Selection to do so. Despite doubters and opposers, there has been lots of evidence to prove it such as Biogeography, Biochemistry, relative dating, embryology, and homology. Biogeography refers to the distribution of plants and animals, while biochemistry refers to DNA similarity

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.

Every organisms are descendents of each another, and are connected by the same family history. This causes the principle of Big Idea number one. All millions of diverse life forms have arrived
