Are significant numbers of humanity the product of an ancient and advanced alien civilization? Have we, across the millennia, been periodically modified and refined as a species? In short, has our genetic make-up been manipulated by otherworldly beings that view human civilization as one big lab experiment? These are controversial and thought-provoking questions. They are also questions that demand answers, answers that may very well be found by examining those people whose blood type is Rh negative.

The vast majority of humankind-85 to 90 percent-is Rh positive, which means a person's red blood cells contain an antigen directly connected to the Rhesus monkey. This antigen is known as the Rh factor. Each and every primate on the planet has this antigen, except for one: the remaining 10 to 15 percent of humans. If the theory of evolution is valid-that each and every one of us is descended from ancient primates-shouldn't we all be Rh positive? Yes, we should. But we're not. The Negatives are unlike the rest of us. They are different. They are the unique individuals whose bloodline may have nothing less than extraterrestrial origins.
