The theory of evolution is one of the best-known scientific theories around. Try to make it through a day without using or hearing the word "evolution" and you'll see just how widespread this theory is.

Evolution is fascinating because it attempts to answer one of the most basic human questions: Where did life, and human beings, come from? The theory of evolution proposes that life and humans arose through a natural process. A very large number of people do not believe this, which is something that keeps evolution in the news.

­In this article, we will explore the theory of evolution and how it works. We will also examine several important areas that show holes in the current theory -- places where scientific research will be working in the coming years in order to complete the theory. The holes are considered by many to be proof that the theory of evolution should be overthrown. As a result, quite a bit of controversy has surrounded evolution ever since it was first proposed.

Let's start off by taking a look at the basic principles of the theory of evolution, look at some examples and then examine the holes.
