Evolution Control is an evolutionary process, in which inhabited planets try to undo the work of humanoid species. The process typically involves the planet forming the source of its core into a Foreteller, which then either destroys the work of the specie or the entirety of the specie it self. The Shape and The Mother are two examples of aggressive foretellers.
Evolution control varies from planet to planet and may even completely ignore the actions of a species, depending on the chemical properties of the planet's core. Procidens was the first known planet to cause evolution control.
