I hate too get in too this late (hate to get into it at all) but i have one question, has science explained morality or evolution of the spirit? does it explain the feeling of good and evil inside us all (or most of us)? I have not read all the post's on this thread so I may be asking questions that have already been answered. I still havent got too see the movie yet but i am planning on going soon!
You have to appreciate the best-guess quality of Science. It's not about a 100% certainty, it's about producing explanations and putting them to the test like some industrial assembly line of a certain object, where at the end of the assembly line is an assessment test of the object's fitness to satisfy certain criteria.
The criteria is reproducing the characteristics of some phenomena that's being studied, and the assembly line is science's iteration of any and all imaginable explanations, commonly called hypothesies and theories. The assembly line is running at full output, trying to come up with the best possible "object".
Does this pattern sound familiar? It is, because it's analogous to evolution. Survival of the fittest.
The best answer to your question I have is that the nearest thing to what you describe that I've heard of are a sort of "evolutionary" (I forget what they called it exactly, sorry) robots, or software, that will (much like 1000 chimps at 1000 typewritters) sort of crank out random solutions to the problem they're presented, and be designed to keep track of which traits of the software are most efficient to accomplish their purpose.
I think it was some guy's pet project, made in his garage, called an "invention machine", or something like that.
Back to your question though, you could read up on "memes" or "memetics", or just general psychology, or pretty much any and all of epistemology or maybe even metaphysics. The problem you're going to run into is the same that some people are running into here: indiscriminate mixing of actual science and abstract philosophy, or even religion.
"has science explained morality or evolution of the spirit? does it explain the feeling of good and evil inside us all (or most of us)?"
"Morality" is pretty subjective, "spirit" is pretty much undefined, and "good and evil" too.
