Charles Darwin's On the Origin of Species Essay

As a naturalist, Darwin discovered how the type species interact differently from the species from other locations that were nearby. That discovery concluded to be the proposal of “natural selection,” which is a principle that explains that nature selects the

Charles Darwin proposed that the mechanism of evolution is natural selection and that it explains

“These birds look similar to each other in plumage and song, yet closer observation reveals that they all differ from one another in how their beaks look and work” (Abzhanov, A., 2010). Darwin believed that if given enough time, a species would adapt to its environment, “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change” (Darwin, C., 1859). Charles Darwin recognized that natural selection was the primary factor for evolution, not limited to only birds and plants, but to humans as well.

He finally observed that overtime these birds developed different physical characteristics to help them be able to survive and adapt to their surroundings. Darwin developed the “Natural Selection” theory that stated that plants and animals adapt to their surroundings and environments in order to survive. He also stated that older generations of these species would eventually die out, because they do not have the newer characteristics that needed to be developed in order to live.

For example, the evolution of an eye went through a large number of intermediate steps all of which had some incremental changes when compared to the previous ones. The idea that all evolution was gradual is contested by some authors claiming that some evolutionary changes of profound type happened in only one or two generations when organisms containing some profound genetic mutations found them very useful and established a whole new species (Theißen 2009). Theißen (2009), for instance, claims that the emergence of some features of some organisms cannot be explained any other way than postulating these sudden profound changes. However, gradualism should not be excluded and it can be regarded as a normal mode of evolutionary progress, while these sudden “saltations” provided an alternative mode.

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

“If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing environment” (O’Neil, 1998-2013). Scientists call this reproductive success. “Within a specific environment context, one genotype will be better than another genotype in survival or reproduction for certain reasons having to do with the way its particular features relate to the environment or relate to other organisms within the population” (Futuyma, 2000-2014). The theory of evolution is explicable through various kinds of scientific research.

In the origin of the species Darwin argues that every species adapt in order to survive. Natural selection is the form where parents transfer what is necessary to live in a certain environment and with time the descendants start changing accordingly to the necessities to stay alive. Darwin mentions that those species that change will survive and prosper, but on the other hand, the species incapable of changing will die and become

The concept of natural selection suggests that individuals/species with useful adaptations have higher chance of survival than those who cannot adjust to environmental change. It increases variability and produces favorable characteristics in later generations to adapt to life changes. In the end, individuals with natural selection characteristics evolves and withstands natural threats much better than those who don’t. Species that are unable to change to fit in new environment would eventually go extinct.

Charles Darwin originally argued that all existing organism are the modified descendants of one or a few simple ancestors that arose on Earth in the distant past (Smith, 1989). Darwin also argued that the main driving force of evolution is what he defined as natural selection. Natural selection is the process that reproductively successful or environmentally well-adapted traits of individuals, is often as a result of mutation, inherited and become a part of a population’s traits through generations (Bell, 2008). In simple words, natural selection is a change in an allele frequency in a population over time. In order to prove this idea, Darwin carried out artificial genetic

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.

Charles Darwin was a man who shaped the way in which we think about evolution in modern times. He brought forth and described the theory of natural selection and survival of the fittest. To fully understand modern evolutionary thoughts it is necessary for one to completely understand the early theories of Charles Darwin. In this paper I will provide the reader with a complete background on Charles Darwin, describe his voyage on the HMS Beagle, and discuss his theory of natural selection.

     Darwin’s Theories upset the church, one of the things that he proposed was that all living things may have descended from the same species. Today it is believed that life may have started as replicating molecules. Darwin introduced the idea that life is not just evolving but the earth is also changing. This went against creationism, the Bible says that god created the world and all the animals. It also separated man from the animals because god created man in

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
