Human race

There are seven distinct human races. A human race is defined as a human species that evolved separately from other human species, but is able to prorecreate with other races.

The seven races are:
 * Harvian race
 * Hularian race
 * Liosannian race
 * Mienupian race
 * Mithridhian race
 * Sgesensian race
 * Terran race

There are two cases where prorecreation is not possible: Mienupians with Liosannians, and Sgesensians with either Mienupians or Hularians. These races are able to have sexual relations naturally, however. They can prorecreate by means of artificial impregnation.
