Evolution & entropy?

In class on Tuesday, we discussed evolution as a process that strives to get to newer places, exploring new possibilities rather than having a goal or aim. Life forms become progressively more complex over time and instead of this progression reaching perfection, it is simply moving forward with a single goal/aim in mind. When Professor Grobstein mentioned evolution as part chance and part causal relations, I think of entropy. Entropy is a measure of disorder and is also nature's way of creating the most probable outcome in a given environment or situation. If chemical reactions all around are guided by entropy and knowing that life is a combination of many chemical reactions, can we say that the development and change of life forms over time (evolution) is guided by entropy as well?
