Xurlan

The Xurlan are an extinct humanoid species. They were tall and thin with an moai shaped head. On their old homeworld, one scientist Ftruloi experimented on his own people in a psychic project to "create gods". Eventually the psychics turned on him and the normal population, destroying their people.

Doctor Franklin Jones tried to recreate the experiment on Earth after discovering the flaw in the experiment, the DNA was deteriorating when the subjects were injected. So he chose to try the experiment of newborn children. Which turned out to be mostly a success.
