The Theory of Evolution and Survival of the Fittest Essay

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†¦show more content†¦These are the most famous. Survival of the fittest is the best way to describe evolution. If an organism is well suited for its environment, it will not be killed off as fast as an organism not well suited for the environment. Organisms in the same environment with the same eating habits are constantly competing for resources, so whichever organism is better suited will survive and kill off the weaker or less suited organisms. The organism surviving better will then pass his beneficial genes to his offspring and they will be better suited too. Since these organisms are better suited for their environment, they will keep surviving and reproducing. Later on, the whole population will have the characteristic bettering them for their environment, making it easier for them to survive as well. The beneficial changes to the organism can later result in an entirely different creature. Another piece of evidence regarding evolution is vestigial organs. A vestigial organ is an organ that was once useful in an animal†™s or humans’ evolutionary past, but that now is useless or very close to useless. There are some organs in organisms’ bodies that are useless and do not serve a purpose so why are they there? For example, the appendix in humans is completely unnecessary and does not serve a purpose in the anatomy of a human body. In theory, vestigial organs may have been useful to animals and humans in their past, but as they evolved; the organShow MoreRelatedThe Finches From The Galapagos Island1255 Words   |  6 PagesChange is the key factor in a species survival, whether that change, is being minimal or extremely dramatic, and without change a species have condemned itself to extinction. Animals have learned to adapt to their surroundings in order to survive, and with these adaptation people can witness new breeds added to the spectrum and see them flourish. Breeds can be defined as a stock of animals or plants within a species having a distinctive appearance and typically hav ing been developed by deliberateRead MoreCharles Darwin s Theory Of Evolution1173 Words   |  5 Pages It is time to start believing. Evolutionary theories were first proposed by Charles Darwin in the 19th century, and 150 years later, these ideas are still being studied and proven today. Charles Darwin set the basis for these discoveries. Natural Selection and survival of the fittest are two examples of evolution. Charles Darwin once exclaimed, â€Å"It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.† ThisRead MoreArgument Against Evolution By Natural Selection1208 Words   |  5 Pages Comment Powered by Li 1 UCOR 1620 02 Darwin the idea of Evolution Mingxi Li(Jessie) Mar. 8th, 2017 Assignment 3 Argument against Evolution by Natural Selection Abstract Natural selection is one of the numerous theories that attempt to explain the evolution of living things from their primitive origins to the more advanced organisms existing today.

In 1859, he published his classic work, The Origin of Species by Means of Natural Selection, where he summarizes his theory of evolution with the thought of struggle for survival, or natural selection. Furthermore, natural selection is the idea of groups of species surviving through generations by adapting to changes in the environment and using certain characteristics as an advantage. In additionRead MoreSocial Darwinism Is An Ideology Of Society1566 Words   |  7 PagesSocial Darwinism is an ideology of society that seeks to apply biological concepts of the laws of evolution by natural selection of evolutionary theory to sociology and politics, often with the assumption that conflict between groups in society leads to social progress a s superior groups outcompete inferior ones.
