Darwin’s Four Main Principles

In the era when Charles Darwin was alive (1809-1882), most of the Western culture believed that the world was created by God. At that time, they believe our world is always such a thing. Therefore, when Darwin wrote "origin of species", it shocked the cultural and scientific perspectives of his era. He believes that evolution is one of the most popular theories of his time through natural selection, but today it is widely accepted in most countries of the world.

The term "social Darwinism" was made by Thomas Henry Huxley in 1860's comment on Darwin's "Origin of Species". However, the modern concept of social Darwinism did not appear until the 1940s and 1950s, with the emergence of ideologies like fascism. . It is used to support the laissez - faireism and political conservatism and to oppose the rise of fascism. The main supporters of social Darwinism are Herbert Spencer, Thomas Malthus and William Graham Sumner. But they explicitly did not use the term "social Darwinism" to explain their work.

Darwin replied that natural selection was inspired by Thomas Robert Malthus' view of population growth. His theory of evolution consists of four main ideas and principles. Only one of them is unique to Darwin. Principle 1 states that all species change babies over time. The species that exist today are different from their ancestors. In addition, populations of species from different geographically distinct locations differ slightly in morphology and behavior (evolution) (Hothersall, 2004). Principle 2 shows that we all have a common ancestor. The best example of this principle is that he believes that humans and chimpanzees share a common ancestry 8 million years ago. According to this principle, common ancestors explain the similarity of organisms grouped together (Hothersall, 2004). The third principle is simply to state or point out that evolutionary changes are moderate and slow.
