The theory of Evolution is now a widely accepted means of explaining the way that life has developed on this earth. It is now believed by the majority of the scientific community and it is often used to explain biological phenomenon. The Theory of Evolution was based on the fossil layer and experiments conducted by the founder of evolution, Charles Darwin. In Darwin's time certain points of his argument were flawed due to the lack of the development of science at that time. Since then, the renewed interest in the work of Gregor Mendel and other new discoveries in genetics have given evolution the necessary processes required to explain the specifics of inheritance. There have been other theories used to explain the development of life on earth but evolution has the most evidence and most followers in the modern scientific community.

To begin I would like to state the doctrine of which evolution is based on.

It can be surmised in four parts. These premises are used to derive the theory of evolution - that is the theory that less complex forms of life developed into larger, more complex ones. The first point is that there is stability in reproduction. That is, individuals produce offspring similar to their parents. I am of the species human and I have characteristics of my parents such as my eye color, hair color, height, and other phenotypes as well as the predisposition towards diseases expressed within my genotypes.

The second premise is that, all though organisms produce like organisms, there are variations. I am not an exact clone of my parents and have variations within both my phenotypes and genotypes. So while, there are similarities among progeny there are also differences. Also, these variations may be inherited among offspring. Just as I stated...
