The population of Morgs on the planet were primitive, but plentiful. Because they possessed no organized civilization, they remained widely scattered throughout the planet's surface.
Around 8000 BC, when a glacial age reoccurred, an underground complex was developed for the women, while the men remained above, causing a male-female schism.
- These men would become the primitive beings known as the Morg.
When the crew of the USS Enterprise, NCC-1701 encountered the Morgs in 2268, they did not know the meaning of the word "female" or "mate", and feared "the others", whom they called the "givers of pain and delight".
- These "others" were later determined to be their female counterparts, the Eymorgs.
- Captain Kirk, Dr. McCoy and Chief Engineer Scott were forced to fight two enslaved Morg guards in order to retrieve their equipment.
- The status of this rejoined civilization is currently unknown.
