Does evolving from a living thing such as a tiny cell sound crazy? The theory of evolution, in basic terms, speculates that all life is related and has descended from a common ancestor. The theory of evolution and survival of the fittest has been around since the time of the ancient Greeks and maybe earlier. Evolution has provided people of the world with an explanation of how everyone and everything got here. Although, this theory has sparked a lot of debate, the factual side of evolution is quite interesting.
Contrary to popular belief, Charles Darwin was not the first person to come up with evolution. It’s been around for many centuries. For example, Mark Felix (170-250 AD) and Lactantious (260-330 AD) were believers in evolution way before Darwin existed, along with many other people. For many years, scientists have kept researching and examining what would have to happen in order for evolution to occur. Could it be true?
Evolution is not something that happened over night, it happened over millions of years. A species evolves by the process of natural selection, or survival of the fittest. Whichever organism is better fitted to its environment and way of life, will survive and pass on the genes necessary to survive. Many researchers and scientists have seen this happen, such as Charles Darwin.
There are very many theories of how evolution occurs. For example, there’s evolution by natural selection. This means that nature selects the weakest organisms with no beneficial mutations and they are killed of while stronger ones survive. There’s also common descent, which means that organisms are descended from one or a lot of common ancestors and have diversified from the original. Next, there is gradualism which means evolutio...

The Survival Of The Fittest Essay

- A tautology is a logical truth that is often considered redundant and empty with respect to explanatory power. Stating that “all dogs are dogs” does not reveal any new information about the world, and therefore is considered a fairly useless insight. Some critics say the “survival of the fittest” is tautological because “fitness” is said to be defined by survival rates, reducing to “the survival of the survivors.” This criticism is mostly raised by creationists, who often believe this “tautological problem” leads to the failure of evolution....   [tags: Evolution, Natural selection]

The 's Theory Of Survival Of The Fittest Essay

- Humans, as whole, are pretty split when it comes to the story of creation and how we came to be. In some renditions the universe went through an inexplicable change causing all types of collisions and creations, ultimately leading to the creation of earth and the milky way galaxy.
