*Clears throat*
Um, since we're apparently making a ruling that recreating earthlike flora and fauna is a statistical impossibility, this actually means that no humans on SP would have a source of nutrition (since the same logic would apply to any of the multitudinous complex strings of amino acids and hydrocarbons it takes to make your body function), and as such, any humans on the board who have lived longer than, let's say...
25 weeks, assuming you're really fat, should be dead.
Equally, the same principle should be applied to parallel technology curves making cross-planet technology incompatible (and as such rendering most universal communications useless, along with 99% of any trading that could possibly happen), and I'm sure I don't need to point out how it applies to linguistics. Perhaps this is one of those areas where we brush over the statistical probabilities in favour of good roleplaying? Hm?
Also, Hiro, be aware that I am more than happy to read over every request you've ever made and find every scientific inaccuracy you've left in them. >=D
