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?<br><br>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.<br><br>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.
