Evolution is the gradual change overtime of an organism. The belief is that the earth was changed and caused the animals to change along with it. It teaches that we were all once a different thing but through common ancestors we became what we are today. Evolution uses facts such as the fossil record, DNA, natural selection, similarity in structure, and geographical evidence to support it's theory.
The fossil record is used to support evolution by using fossils that have been found that possibly have characteristics of two different species that could be used as a transitional fossil. The fossil record shows that change in animals through out the years. There are also major gaps in the fossil record that show no fossils and no evidence for evolution. The fossil record can also be inaccurate due to natural changes and disasters that have taken place in the earth. Scientists use DNA evidence to show that humans and apes must have a common ancestor because they have such similar DNA. THis is the only way that evolution can be tested today. Although we have much of the same DNA we still have 120 million base pairs that are different. Natural selection is used as evidence for evolution because it helps explain why evolution took place and why it was needed. Natural selection can be used as evidence but it also is just a natural process for sustaining life and keeping population levels under control. Similiarity in structure shows that we have some of the same bones and placements as other animals even though we may use them differently. This shows that we changed to adapt to our needs. Geographical evidence shows that we change to our enviornment and the food sources we have available. Evolution uses this to explain why there are so many different species that are so different in different parts of the earth.
Natural Selection is a very strong point in evolution because it shows survival of the fittest. It shows that animals chnged to make themselves better able to survive in their new enviornments. This helps scientists use evolution to show that the earth changed and caused a major disruption this helps explain extinction. Extinction tells us that there were species that couldn't adapt fast enough so they were either taken out by other animlas or the climate caused them to die.
DNA is one of the most concrete ways to show the commonalities that different species have. Scientists like to prove evolution with DNA evidence because it is the only one that can be tested today. DNA is very complex and people think that when we have about 90% the same DNA as something that means we are very much the same. What the scientists don't tell use is that there are millions and millions of base pairs that aren't the same so we aren't as closely related as they would like us to believe.
Human evolution is the belief that we share a common ancestor with a monkey. Human evolution is often thought of the wrong way people look at the pictures that show monkeys evolving and think we came directly from monkeys when in the real truth that isn't what evolution teaches it teaches we have a common ancestor and are not directly from monkeys. Human evolution uses many skeletal remains as proof to show how we evolved. When reasearching the skeletal evidence I found that much of it has been changed to go along with the theory evolution presents. I don't think it is right for someone to change the skeletal remains and then pass them on as the truth. I don't believe in evolution for many reasons one of them being the lack of true evidence that hasn't been tampered with. I think we would need to find the real transitional fossils to prove evolution. I believe in the creationist viewpoint that we were created by God not in millions of years but in a matter of days. I believe in microevolution in the fact that it says species change within themselves to become better able to survive of have certain charateristics. I have learned so much that I didn't know about evolution practically everythin I talked about in this paper is the knowledge I have gained in the area of evolution. I know more and I will be better able to defend my views on evolution.
