So, uh, back to Destiny. Humanity's origins are obvious as are the Exos. Humanity evolved on Earth, and when the Traveler came around, they also created the Exos. However, the Awoken are an entirely different matter. We know that there are definitely members outside the City whom don't exactly appreciate its confines, and the same may apply to some Humans and Exos, but we've only seen it with an Awoken so far.

If the Exos came about during the Golden Age, perhaps the Awoken did as well? There was talk of the Human lifespan being tripled during this Golden Age. However, perhaps there is more to it than that. Maybe the Awoken are the ultimate culmination of this effect, since one of the main inspirations for them are magical beings like elves, whom as we know have very extended lifespans outside of non-natural death causes.

By no means should any of this be taken with more than a grain of salt, but it's my own personal idea, as is with all the others I've posted below.
