One interesting way to look at/remember this it is through history. Evolution by some early thinkers was thought of often as Ernst Haekel's tree of life[1]. In this representation of life it is directed and goal based. This is a misunderstanding of evolution that was common in a world that saw humanity as the peak of the process of evolution. For this reason Darwin perferred to think of it as a directionless bush rather than a directed tree. 1: http://en.wikipedia.org/wiki/File:Tree_of_life_by_Haeckel.jpg http://en.wikipedia.org/wiki/File:Tree_of_life_by_Haeckel.jp...
