Darwin 's theory of evolution states that all life is related in one way or another. He explains this by saying that due to random gene mutations form more advanced organisms from their simplistic counterpart. This feeds into the second half of his theory. This part of the theory is natural selection, or survival of the fittest. When the random gene mutations occur they sometimes form attributes that aid the survival of the organism, and it builds from there until completely new organisms are made.
Charles Darwin is one of the main contributing scientists to the theory of evolution. Darwin developed this theory when he went on his five year voyage around the world. When he arrived at the Galapagos islands he noticed a difference between the same species of bird from island to island. The finches had different beaks for their environment. some had curved beaks while others had straight pointy beaks so. This adaptation occurred because of the type of food the finches were trying to eat. For example the ones that had beaks suited for eating c...

...hen the last species of a plant or animal dies off due to natural causes or human interactions. It is believed “By some estimates, over 99% of the species that have ever lived have gone extinct” (Venema). When a mass extinction occurs it opens up the opportunity for a new species to thrive in an environment that nothing else could. An example of a mass extinction that occurred happened at the end of the permian. During this extinction event it is believed that thousands of years of volcanic activity raised the CO2 level so quickly that the species alive couldn 't adapt in time and resulted in a mass extinction (Venema).
Evolution has played a very important part in ours lives. without it we may still have tails, or we may not even be here today. From our primate ancestors to the several mass extinctions it is evident that evolution is and always will be important.

- Evolution, what is evolution. Evolution is the process by which different kinds of organisms have changed and adapted from their earlier forms. Evolution relates so closely to biology because biology is the study of life and evolution is how living organisms have adapted to the environment. My goal for this paper is to explore evolution in mammals, the basic theory of evolution, beliefs of evolution, the main contributors of evolution, evolution in humans, evolution in monkeys, things that humans lost from evolution, as well as extinctions....

- “Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth”. Evolution occurs within species and not individuals. Some people believe that evolution theory is a myth and it lacks scientific evidence and others believe that there is supporting evidence. Evolution in the living organisms is believed to have been continuing for the past three thousand million years. Evolution theory is not a modern discovery as it appeared in early writings....

- All cultures have origin stories or legends to explain their beginning and the beginning of the world. Some culture stories are based in creationism, and others are based in the science of evolution. Evolution is a widely accepted theory of how species change over time. There are four forces of evolution-- mutation, gene flow, genetic drift, and natural selection-- all of which have an effect on all species undergoing adaptation. From microevolution to macroevolution, change is happening to all the time.... [tags: Evolution, Population genetics, Genetics, Gene]

- In all parts of the the world both past and present, mankind searches for the answers how earth and its complex life forms came to be. Over the years there have been many theories that have surfaced, but the one most popular is the evolution theory. Evolution is taught now in science classrooms all over the world, the concepts based on charles darwin’s theory regarding evolution and natural selection. The science community has accepted evolution has how the earth came into form. however since no one present when the earth was created no one knows for sure, but there is one theory that explains how, why, and when, and that is creation....

- How evolution happens Evolution is change.S Evolution is a certain species changing to become better adapted to their surroundings and in the end this modification causes this species to become a new breed altogether. There was no scientist that understood how evolution works until Charles Darwin and Alfred Russel Wallace (See figure 1) explained it to them. Lots of scientists had realised that plants and animals change with time, as palaeontologists could track the evolution of life in the fossil record....

- There are many ways to explain how Earth and everything else came to be. Such as, Uniformitarianism, Catastrophism, Gradualism, and Punctuated Equilibrium. Generally, Uniformitarianism and Catastrophism are grouped together while Punctuated Equilibrium and Gradualism are grouped together separately from Uniformitarianism and Catastrophism. Gradualism and Punctuated Equilibrium are usually looked at through a biblical stand point rather than how Uniformitarianism and Catastrophism are looked at from the opposite view....

- Since the publishing of Charles Darwin’s Origin of Species, where the theory of evolution has arisen from, people have debated Creationism versus Evolution. Through supporting facts and statements the theory of evolution will be defended as being more than just a theory, and proven as fact. Evolution as a fact is reinforced through; scientific studies on DNA, genetics and its mutilation, the Fossil Record and the change in earlier species that has been found, and finally the distribution of related species of animals over a broad geographical range....

- Man could not evolve to any other state, because he was made in the ultimate state. He was made in the image and likeness of the Father so there was no need for evolution; hence, there was no sign of evolution from the beginning. Since sin came into the world, man has been deceived into thinking there is evolution. We are not talking about the theory of evolution that says man started from an amoeba or as an ape and eventually began to walk upright; not that evolution, but evolution in the sense of development....

- What makes a primate a primate. A primate is defined by its many incredible features. A primate is a mammal that has certain characteristics such as: flexible fingers and toes, opposable thumbs, flatter face than other mammals, eyes that face forward and spaced close together, large and complex cerebrum, and social animals. What makes a primate a primate is its characteristics. Some of the physical features primates are identified by is their teeth, snouts, eyes, ears, arms, legs, fingers, and toes.... [tags: Evolution]

- The purpose of this essay is not to prove “Darwinian” evolution, as the writer would be performing a feat already done by others, but to examine a certain track of thought amongst Creation proponents. Specifically their noting certain improbabilities of evolution's ability to “design.” I'll evade defining the individual concepts because they've all been described before, and far better than I could manage, although I'll point out that micro/macro evolution distinction is largely Creationist lingo, as is the “kind” terminology....
