Evolution Evidence

A detailed Summary of Evolution Evidence

Evolution is the process of developmental unfolding that takes place over a long period of time, and starts with a simple form then gradually grows into a more complex organism. Humans, for example, have been evolving for about eight million years to mold us into what we are today. Evolution has been an extraordinary adventure through time: the evidence is the storyteller. All life started from a simple being and has stemmed to become more complex by two dominating factors-- natural selection and mutation. These are the key to evolutionary change and result in the complexity of the organism, therefore increases the survival rate. An example of this is used on girraffes. It starts with a mutation, imagine them before their long towering necks; the first giraffe that ever began to have one, was able to survive better than the one's that did not. This mutation is now beneficial to the giraffe because the food source on the ground was beginning to become scarce. By natural selection, the giraffe with the mutated long neck has a better chance of survival. They reproduce and pass down their modified genes, and eventually obtaining the leaves on the high trees are the only way to survive. This proc

Evolution is a fact of life. There is much debate whether evolution is fact or fiction. Fictions explanation for how the world is to the present date, begins with all humans were created in the image of God. The first two humans he created was a male and female: Adam and Eve. This theory has been proven false. There is a whole timeline of changes that humans have gone through since they had their first mutation, and stood on two feet instead of four like their closest relative: the ape. Three factual evidences that supports evolution's records in the journey through time are-- fossils records, biochemical similarity, and vestigial organs.

In conclusion, Adam and Eve were not the first creature on earth; nor did they start out in that form. 4.6 billion years bacteria was the only life on earth, humans are the newest part of the collection to that timeline at 8 million years. Further learning on this topic can be found in the book The Sciences by James Trefil and Robert Hazen and web site- http:whyfiles,org/095evolution/bibiol.html. Also various displays at the Museum of Natural History gives an remarkable visual display of the journey through evolution.

Each organism carries a record in their DNA, or deoxyribonucleic acid. It stores all the genetic information-- this is what the biochemical evidence it traced from. In fact, "Molecular similarities on DNA, the genetic memory molecule, indicate a common heritage. Since chimps and humans share about 99 percent of their DNA, we know we shared an ancestor in the fairl
