map room features

as the post before mentions, i think that there is ALOT going on that we dont see in the trailers, as is usually the case with great films, and something tells me that there are MANY different forms of parasites here. the thing that David pulls out of what seems like one of the urns could be (and it was alluded to by someone else) some sort of embryo/seed pod, where different species are hatched. the seat that David is seen sitting in in the navigation room could be a laboratory where they create DNA thats never existed before, manipulating it like David is, maybe with sounds and different encouragements, and they introduce them to the seeds in the urns to see what they can create. the pilots chair, if these things are true, may be used like a telescope, where they can search for planets to plant their new species...that would explain why the big map would be there. what hasnt been discussed, i believe, is why the space jockey would need to be strapped in to that chair to the extent that he is? i realize the need for seatbelts, but he's practically getting graphed to that thing. it could be that he controls the ship as if he's part of it, staying with the bio-mechanical theme, or something else.
