I too get sick of the depictions of aliens as 'one culture societies' (Pretty much every race in star trek) or that they're humanoid with weird foreheads. On the other hand though, You look at things like Star Wars and then you have to question how species in that evolved. Suspension of disbelief can only go so far...
See, now this is something I feel I'd have to disagree with. I've read quite a few books on evolution and what I gathered from those is that the majority of evolutionists beleive that even if the exact same conditions occurred as they did on earth when life started, and I mean the EXACT same conditions, then life itself would evole entirely differently. Thats not to say the planet would be populated with entirely different forms of life (though we don't know, it is impossible for us to imagine an ecosystem without the different groupings of species we have here on earth) but its something we are in fact not capable of knowing.Valanthe said:You know, there was an article I read not that long ago, maybe it was a video, I'm not certain, I'll update this post if I can track it down. Anyway, this article stated that if life evolved on a planet that was similar to ours, with it's Nitrogen/Oxygen atmosphere and stable Yellow sun, that species would evolve in very simlar patterns to ours, with mostly superfluous alterations. This article went into much more detail than I'm able to, but the gist of it is that the OP isn't that far off in thinking that a "Mass Effect" style alien that is anatomically similar to humans isn't such an 'alien' idea.
However, all of that gets thrown out the window as soon as you get out of the physical world and start talking psychology or culture. There are so many variables and simple coincidences that drastically shape a person's, or alien's psyche that expecting an alien to behave like a human is like asking a fish to smell the roses.
I could kee going on about this but I think I'll stop and try to find that article
