Today I was thinking about how it's said the Gungans' technology is mainly organicly grown. Now obviously this would be a very sophiscated thing to develop for a species as primitive as them and they just live in Naboo's Swamps. Then we have Kamino, a vast water planet in which we only saw a couple of surface complexes. So we're led to believe that everything that we saw was just out of those surface networks. Doubtful.
If the Gungans could have the sort of technology they have, then what could the highly advanced, sophisticated and very alien Kaminoians have under the surface? For all we know they've surpassed the Gungans in organic technology and have mega-underwater cities under the surface.
Maybe the Gungan's technology isn't original, Kamino doesn't seem as if it would be far off from Naboo, considering Obi went from Kamino to Geonosis pretty quick, and Anakin and Padme were able to go from Naboo, to Tatooine to Geonosis rather quickly as well. Could the Kaminoians have evolved on Naboo, been able to form Kamino, and then leave ancient technology behind? Obviously they couldn't have used organic material for space travel because it would die from the vaccuum of space, but the Nabooians could have also evolved after the Kaminoians left. The Kaminoians could possibly also leave ancient technology on the surface as well, maybe this technology being for space travel rather than water travel.
