Hey, thanks for replying, your answer is excellent :)
Regarding the upright stance things, how do you see Alex the African Grey Parrot evolving towards becoming a spacefaring species without going towards an upright stance? He's smart, but he'll need to get smarter.
Regarding the upright stance thing, if you read again you'll notice that I qualified my assertion with "non-marine". Once we already ruled out the idea of marine organisms becoming spacefaring, there's no point arguing about things like whether giant squids can be spacefaring.
Naturally, I haven't answered your every point, because you made some valid points.
