Actually, according natural selection, evolution is an accidental process. It happens as a result of "how particles happen to bounce around" and according to unthinking rules.
Evolution and natural selection are two different things so they should be discussed seperately.
Evolution is not an accident, it is a physical change by an organism driven by it's will to survive. A fish didn't just happen to grow legs, a tiger didn't just happen to get stripes, it's physiology changed over time through the need to better allow it to survive in it's unique environment.
Natural selection is what an organism does conciously or unconciously whose decisions (selections) are at base driven by the will of that organism to survive and as I have said, the only law we seem to be bound to is the law of survival.
I do agree however, that there are many people who do what they do simply because of the way "particles bounce around in their head" with little or no understanding of the whats and why's or even care.
Plato said "The unexamined life is not worth living" which I agree with, if we simply believe that what we percieve we are is all we will ever be, then one is reduced to an animated entity that lives and dies with little or no reason or purpose for it. That is why religions were created in the first place IMO, It was an attempt to give some meaning or explanation for life and the world. The drawback of many religions however (those that support the view of creationism) is that they were written by human beings whose understanding of themselves was that we were at the highest point of evolution itself (not that they even acknowledged it), either through ignorance of evolution or their own egos, I think they miss the mark completely. In that world view, forward movement, evolution or development of the psyche cannot occur, the mind stays in a sort of statsis under the understanding that the only purpose in life is to serve or do the will of an outside entity instead of developing oneself compounded by the fact that thought outside of those frameworks of belief are discouraged, which keeps them in that state. Since evolution occurs from need and not by accident, evolution of the psyche does not and cannot occur under those circumstances.
Overall, the origional article appears to have been written by someone who believes in creationism and they attempt to use the argument of physics to support their claim all tempered by their own understanding and beliefs of our humanity. Debate within those parameteres is really the only strength of that argument, outside of those parameteres- it falls short.
