Makes me wonder what it was that made them evolve to look humanoid, instead of going for something reptile-looking, like salarians or...(I don't really know what turians classifies as, but similar to them)
It would largely depend on what sort of creature they were descended from on an evolutionary basis. Humanity, ofr example, has body hair as a throwback to our ancestors that required thicker hair/fur to survive the environments.
If there was no Ice age like event to require that sort of evolution, then hair would likely
not be present on the creature. Examples: turians, salarians. During their evolution, hair was unnecessary or counterproductive.
Unfortunately, we have too little information available to create a valid, evidence based theory from speculation. We know that Rannoch had a
very different way of transmitting diseases and pollens/pathogens. And that it is more arid than earth. We do not know if quarians are descended from predators (though given their body shape, this is a viable if unsupported conclusion); we do not know what actual environment spawned them. Temperate, Tropical? Land based? Water based (since it is more arid, water locations would be more important)?
We simply do not have the information to reach non-speculative conclusions.
Of course, we can speculate all we want. And fill in the blanks as fic writers (I'm looking at you, Buddha and Cal. Glaring at you, Red!) with our favorite theories. I know I do. Because let's face it - quarians are fascinating, Tali especially, and it is
fun to speculate!
