Darwin's Theory of Natural Selection

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

In 1831, Charles Darwin, proposed a theory of evolution occurring by the process of natural selection. This has come to be known as the Theory of Natural Selection. Darwin worked on his theory for 20 years and after learning that Alfred Russel Wallace, another naturalist, had developed similar ideas, the two made a joint announcement of their discovery in 1858. Darwin published 'On the Origin of Species by Means of Natural Selection' in 1859, 28 years after he proposed his theory of natural selection. [1]

In this work, Charles Darwin frequently observes and references the variation in traits amongst individuals in a population. He observed that nature selects from existing varieties the traits most suited for a particular environment. He also proposes that species descend from common ancestors, undergoing various modifications in the course of time. This concept is described by Darwin as “descent with modification” or the new variations present in new generations resulting from natural selection. One of Darwin’s more convincing points is made by way of metaphor. He wrote, “The face of Nature may be compared to a yielding surface, with ten thousand sharp wedges packed close together and driven inwards with incessant blows, sometimes one wedge

To begin, let’s start off with the meaning of evolution. Evolution is a process where something changes into a different but better form. Evolution is made up of three different components, which are natural selection, macro-evolution, and micro-evolution. In this essay, we’re going to focus more on natural selection. Natural selection is the selection of an organism which is more often fit to its environment. For example, if you had black and white moths on a black tree trunk. Who would survive? The black moths because they are better fit for survival because they’re not easily seen. Now that we understand that, let’s talk about Darwin’s theory of Evolution by natural selection. In this theory he developed basically explained how organisms

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.

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

Over time, different species learn to adapt to their living environment in order to survive. If a genetic change of a characteristic is passed down through generations, a formation of a new species occurs (G, Linstead et. al., 2012). A variation to the characteristic of an individual can increase its survival and this provides more opportunities to reproduce. When the individual reproduces, the offspring benefit in result of the heritable genes and eventually through generations, the variants will be spread throughout the entire population (Montgomery, 2009). Charles Darwin’s theory of natural selection can be supported through both fossils and homologous structures.

From the simplest single celled organism all the way to humans, evolution has been the driving force behind every single lifeform that ever lived. Evolution is the most scientifically accepted theory of how all living organisms came to be. It states that overtime organism change, and the way they change is through natural selection. Natural selection is a theory first coined by Charles Darwin in 1859. He proved that overtime there are changes in a species’ traits to greater enhance that individual’s chances to survive and 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.

In the event that you take a gander at the general population around you, would they say they are all the same?What would happen on the off chance that we lived in this present reality where all the food was kept 8 feet off the ground there was genuinely no way you could get it if you weren't tall? Without a doubt, the short people would die. The taller ones would increase in population, and a little while later, as opposed to a population of people of all sizes, you would have a population of recently tall people. Living things that are most proper, or balanced, to their environment survive and repeat. Those that are not, can't survive. This strategy is known as Natural Selection. This methodology clears up how Charles Darwin's theory of "progression" can happen.

The theory of evolution by natural selection exercises two major concepts. The first concept being evolution, which is what happened to all species. Secondly, natural selection is the concept of how the evolution happened. While Darwin was not the first to propose the theory of evolution, he and a man named Alfred Wallace were the ones to offer intelligible descriptions of how this phenomenon occurred.

While studying botany at Cambridge University, Charles Darwin was offered a chance to work as an unpaid naturalist on the HMS Beagle, a naval vessel embarking on an exploratory voyage around the world. In the course of nearly five years at sea – during which time the Beagle surveyed the coast of South America and stopped in such places as Australia and, most famously, the Galapagos Islands – Darwin took advantage of countless opportunities to observe plant and animal life and to collect both living and fossilized specimens for later study.

Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift (Understanding Evolution, n.d.). Charles Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification" (Discover, 2017). Natural selection needs some starting material, and that starting material is heritable variation (Khan Academy, 2017). For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature as well as the differences needing to be heritable, determined by the organism's' genes (Khan Academy, 2017). Individuals that are poorly adapted to their environment are less likely to survive

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859. It is when an animal changes over time it changes its heritable physical or behavioral traits. This happens so a species is better suited to live in an environment and to have more offspring. Evolution by natural selection is one of the best substantiated theories in the history of science due to is evidence from paleontology, geology, genetics, to developmental biology.

The Theory of Natural Selection was first proposed by Charles Darwin in his work titled On the Origin of Species by Means of Natural Selection or the Preservation of Favoured Races in the Struggle for life published in 1859. Darwin’s theory states that because of competition for finite resources within a habitat individuals must compete for survival and those more adapted to their specific environments have a greater success in surviving to maturity which enables them the opportunity to successfully reproduce. Individuals that successfully reproduce will pass down to their offspring the traits that gave then an advantage in survival to maturity and over long periods of time this can cause transformation within a species.
