Essay about Darwin’s Four Main Principles - 465 Words

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. The first principle of Darwin’s theory is that individuals vary in many heritable traits, and that no two individuals are exactly alike. He first noticed this during his observations of the different†¦show more content†¦This inequality creates a struggle for survival among individuals within that environment. This struggle leads to the death of the individuals who are not able to survive within the environments limitations, and the only individual remaining reproduce. Depending on the resources that are available, as in food, water, weather, etc., part of the population will not be able to survive and reproduce. Third, individuals who are best fit for the current environment leave a disproportionaly large number of offspring compared to individuals who are not fit. When that happens over many generations a species’ gene pool changes to only include the traits that are a best fit for ensuring survival of that species, and a new species may evolve. In the case of the Galapagos finches Darwin studied, biologists have since found that one of the differences was their beak size, which were adapted to the specific seeds available to the finches as food on the different islands. This would support this principle as only the birds able to eat the local seeds would be able to survive to reproduce, thus over many generations, new finches with a variety of different beak sizes would â€Å"evolve†.

He came up with a theory that explains how species’ evolve and change. He believed that species change by a process called â€Å"natural selection.† Charles Darwin’s theory of evolution by natural selection can explain the way that a species can evolve and change over time.

One of the biggest is that he called the theory by that name. Albrecht von Haller used the word evolution in 1744 to mean to unroll, so the word was around in Darwins time, but Darwin never used it in the sense we use it today. It was added later by others, including Herbert Spencer, who is responsible for the theory we call Social Darwinism. This theory is misnamed; it is not based on Darwins work, but Spencers.
