Well, it is sort of explained with an indication that the Reapers are responsible for evolution taking place along similar lines. And I suppose theoretically having one's arms free to undertake more complex tasks is a sign of being further along the evolutionary scale.the_dancy_vagrant said:Check out the smartest animals on Earth. Hominids are all semi-bipedal with the exception of humans. And even then, there's that first year where we are technically quadrupeds. Corvids and parrots are bipeds. The only crafty/clever animals that aren't bipedal all live in the ocean.Soviet Heavy said:I'm wondering why we don't see more quadrupedal species. There are millions of different species of them on earth, with very few bipeds in comparison. What makes two legged animals so much better? The Elcor get along fine walking four legged, but nobody else.
But in the end, it's all just sci-fi and there are going to be come inconsistencies here and there. Admittedly the Mass Effect universe is very well engineered to deal with most of those, which is why it's so much harder to swallow that all of the alien races speak English and it never goes explained. Our English, or in the case of the Mass Effect universe, English that's 100 years old. I mean, even here on Earth dialects and accents vary from nation to nation.
