What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into many diverse creatures over time. When you break down this theory into sections you get 6 factors: evolution, gradualism, speciation, common ancestry, natural selection and nonselective mechanisms of evolutionary change.
The first part of the evolution theory is evolution itself. Evolution itself is the idea that a species undergoes a genetic change over time to evolve into something that is very different. These differences are seen in our DNA and are considered mutations at first but slowly become the norm.
The second part of the theory of evolution is gradualism. Gradualism is the idea that it takes many generations to produce a substantial evolutionary change. An example of this change is birds gaining the ability to fly.
The third part of the evolution theory is speciation. Speciation means that different groups of creatures that cannot exchange genes with one another cannot interbreed with one another.
The fourth part of the evolution theory is common ancestry. Common ancestry is the...

Chapter nine is Evolution Redux. Creationists find evolution very convincing but at the same time they still don’t believe it. There is no lack of evidence that points toward evolution being the truth. Every day there is hundreds of observations and experiments that point to evolution being true. Every fossil and piece of DNA observed points to evolution being a fact. The evidence point to evolution being true is so overwhelming it is hard to believe people still believe in a creator.
Evolution is neither moral nor immoral it is just the truth. Once people understand that we are the only creatures that natural selection has created with a brain complex large enough to understand the laws that govern the universe, which is the amazing product of evolution.

- ... This then enables them to leave larger offspring. In turn, having a larger number of descendants means passing over a greater portion of one’s genetic material into the next generation. A greater concentration of a particular gene in future generations of offspring means that the particular species will slowly change its composition in such a way that it will have more and more members with a particular set of traits all of which have an adaptive value. The fossil record is one large pool of evidence supporting the evolutionary explanation for the origin of different species of living organisms.... [tags: religioius movement, ]
