Gosis' species were a humanoid species who inhabited a pre-warp planet in the 22nd century. First Starfleet contact was made by Captain Jonathan Archer, Lieutenant Malcolm Reed and Ensign Hoshi Sato in 2152.
This species' physiology was particularly distinct from that of Humans. The differences were deeper than just outward facial ridges and spots. When Temec, a doctor, compared a scan of Human physiology to their own, he pointed out that his species did not have a liver. Indicating the Human liver on their version of an X-ray, he once said, "We don't even know what this organ does." He also used the X-ray to note that they only had one kidney, describing the second Human kidney as a "redundant renal organ." And his species' blood was neither red nor contained iron. Moreover, iron was a toxic element to their species.
By the 2150s, their race was divided into at least two 'major' political nation states, one of which was called "the Alliance." In 2152, Gosis' faction believed – based on propaganda – that war with the Alliance was inevitable. The war would have been based in part upon "ancestral claims" by the Alliance on Gosis' faction's capital.
The government of at least the area inhabited by General Gosis appeared to be in civilian hands, as evidenced by the attendance of the Enterprise away team at a political rally held by a "Chancellor Kutare". However, the influence of the military was strong.
In the 2150s, the technological level of the planet seemed to be on a rough par with late 20th century Earth, although they hadn't yet "split the atom". They possessed reliable artificial illumination, a knowledge of computers, familiarity with telecommunication, methods of observing internal organs, ways to photograph objects in planetary orbit, automatic projectile weapons, automobiles, trains, and jet aircraft.
As of the 22nd century, the species practiced (or at one time in their past, did practice) a well-developed religion, centered in elaborate temples.
Reed and Sato were impressed with the aesthetics of the architecture of the city they visited. Enterprise orbital scans of the city revealed a dense developmental pattern. Functionally, the architecture was of sufficient design to accommodate a high population density.
