Scientists discovered a strange and foreign protein, which they named HEMO, in the blood of pregnant women. What makes this protein unusual is that the mothers-to-be do not create this protein, which is different than other proteins found in a person’s bloodstream. Instead, only the fetus and the placenta, both in the womb, produce the HEMO protein. While investigating the reason for this, the scientists discovered a direct link between the protein and a human gene that originally was a virus that infected our mammalian ancestors more than 100 million years ago.
In fact, research has found that around 100,000 bits and pieces of alien, as in not-originally-human, viral DNA now makes up about eight percent of our DNA. That means that eight percent of the genetic material that determines who we are as biological human being descends not from our human ancestors, not directly at least, but instead from ancient viruses. In comparison, that is more inherited DNA than any of your great great grandparents provide, which is about 6.25 percent.
