So I'm playing the story again for the 10th time and I've noticed something that bothered me. What is with the lack of hair on aliens? Are you telling me that none your planets were cold enough that your prior evolutionary forms wouldn't need it?
No they may be better against the cold
I think quarians have hair. But you are right id like aliens with hair
And maybe we are so alien for them to have hair 😉
I'll say only this - it's genetics. Reptile species (Salarian/Krogan/Batarian/Prothean) by definition do without hair. I would also consider Turian as a reptile just by looking in the eyes. But hey yahg have some rudimentary hair 'concept'. :P
Asari IMHO are some evolutionary middle ground between reptiles (skin surface) and mammals - in the words of lovely Liara 'other tentacle creature'. They lack obvious genetic trait of reptiles - inborn aggressiveness (yeah Salarian is not really good example, but at least we know they are reptiles and they 'eat flies' :) ).
I think that Bioware didn't actually thought about all races coming from evolution point of view, but it's hard to disagree that outside Humans & Quarians you'll be hard pressed to find more 'hairy ones' - at least in the established (so far) boundaries of the ME Universum.
Look at it that way: It's a the opposite of Star Trek, where almost all alien races looked like Humans, with some addition.... but they all had hair.
Romulans, Vulcans, Klingons, Cardassians, Bajorians´, Andorians, Changelings...ok.. Ferengi not, but they got ears too....
I find this way of evolution fine.
Remember Turians and Krogan have a decent radiating sun in their homesystems..... no need for a sleigh here.
Surkesh is a massive Jungle World, very humid and warm aswell.
Thessia is full of Element Zero. Even the wildlife shows signs of biotic behaviour. Maybe all those millennia in direct Eezo proximity mutated the hair into the semi-flexible cartilage-based scalp-crests we know (as a form of natural organic biotic amplifier.......)
And the Quarians.... well what you don not need, you won't keep.
Maybe they had long seething hair 300 years ago, but that might have been reduced to Rudiments due to living in suits all life long. Their skin has to be quite pale too. But that is academic, as we haven't seen one outside a suit anyway. Why is there no medical database btw???
Salarians have their legs bend similar to Quarians and Turians as I currently realized.
What bothers me is that all are bipedal..... except the keepers and the Rachni.
And why do humans, asari, drell and batarians have 5 fingers, while prothean, krogan, salarian, quarian, yahg, volus, and turian have 3 fingers per hand.....
But then again... only 1 % of the Galaxy is known as are the Mass Relays opened accordingly.
What do you think?
