Gomez's people

Just some useless trivia, but isn't it strange that the hexahedron expects you to be zu'ish? If you look at the evolutionary chart you also don't see Gomez's people on it. Even most of the pictures/paintings in the starting village are of zu'ish people. Does anyone have any idea where they came from??? Even the Hexahedron, who should be some kind of deity, is confused when one of Gomez's kind shows up...
