Survival of the fittest is not just a theory or an idea, it's a way of life.  It has evolved from an idea supported by one man, to a way to justify the ideas of today. Naturalization has taken place with survival of the fittest, naturalization is when social processes are supported by views on nature which actually came from nature in the first place in order to rationalize the same views. These ideas of nature mold the society around us, which supports Peter Coates' fourth concept of nature, that nature is a guide. However, as time goes on sometimes these prevalent social theories change, or evolve (Coates, 1998). Evolution is a slow process in which something changes usually into something more complex, which really helps to describe survival of the fittest. Survival of the fittest is mostly used in terms of organisms evolving to become the most adapted to a certain environment. The organisms who adapted the best are able to survive and produce offspring in the process known as natural selection. One man, Charles Darwin greatly studied these theories, and he also believed in Social Darwinism. That is the theory that humans apply to all of the laws of natural selection as well, not just animals (Merriam-Webster, 2012).
