This post has about as much science as Mythbusters... applaud the effort but in reality the amount of credibility is only slightly better than an old wives tale, a far cry from science. This is not me releasing frustration with Tali fans (I really like Tali's character) nor do I hate mythbusters (enjoy it a lot actually), but calling this science was something I felt obligated to clear up.
Some of the fundamental assumptions you make to determine traits are actually opposite of science, if applicable at all. For example your arguments regarding hair color and melanin are opposite of scientific logic. In order for evolution to occur in a species, there must be selective pressure for a certain mutation. Consider two male rabbits, one that can breathe water and one that can't. Imagine all the female rabbits are on an island in water deep enough to drown a rabbit. In this situation, the rabbit that can breathe water will be able to mate, but the other male rabbit won't. This will cause only water breathing rabbit children to be born because only that male passed on his genes. Consider the same rabbits, but this time the male and female rabbits are in a field with no water deep enough to drown in anywhere near by. In this situation both males will breed and the off spring will be just as much water breathing as not. This means there was no change in the % of each type of rabbit. How this applies to the Quarians is simple, there is no selection against melanin on the flotilla, therefore skin color would not change from what it used to be. Likewise because of the suits, the preference for certain hair colors is lost, meaning all hair colors are passed on equally. Since humans select for preferred hair color, we likely have less hair color diversity than the Quarians (if they have hair).
Secondly, mammal is a taxonomic term developed strictly to classify various forms of life based strictly on what exists on earth. The updated theory of taxonomy is based on the concept that all life diverged from a single common ancestor through genetic mutation, aka evolution. Taking note of the dextro amino acids (which just means their amino acids are bent a the opposite direction), it is clear that Quarians and Humans could not have evolved from a common ancestor. This would suggest that independently occurring development of life on each home planet, which makes sense, bacteria from one planet didn't space travel over to the other before sentient life evolved. Because of this independent development of life, the classification of mammal not only cannot apply to Quarians, there is zero reason to believe Earth mammal traits would collectively evolve convergently. So conclusions about having hair, being warm blooded, or any other mammal trait not expressly stated about Quarians is invalid.
Light emitting eyes is also incorrect, I won't bother getting into the actual science of how vision works and why light emitting eyes would not see anything, but to prove my point go shine a flashlight in your cat or dogs eyes in a dark room. They will "light up" just the same as a Quarian's. I would suggest your seeing this same reflection in Quarian eyes, caused either by a particular morphology unique to their eyes or reflection similar to dog eyes caused in part by refraction due to their visors.
Essentially the only evolution that will change how Quarians look since the time prior to suits are a result of increased fertility or mutations which improve adolescent survivability. Fertility is unlikely because they have laws limiting the number of offspring allowed. Only adolescent survivability is important because after that point they can reproduce and pass on their genes. However, improved immune systems and body control (tiny selective pressure to avoid accidents that would puncture the suit) are the pressures on adolescent children in the migrant fleet, but neither of these would alter physical appearance.
class dismissed.
