They might have been simply the product of evolving under extreme conditions, and therefore need to be able to adapt and survive... so it's just possible that they could have just evolved without genetic engineering. Remember, Halo 04 was built to study and research the Flood... not test different types. If they were engineered, then how come we don't see many different types? Hm?... other than the fact that some subspecies may have died off during their long confidement.
