What Is a Doppelganger?

Bruno: There are only so many ways you can rearrange a face until you're bound at some point to get someone who maybe favors somebody a little bit or even more. A researcher named Manel Esteller from Spain said, I want to try to figure this out. He took 32 pairs of doppelgangers and ran them through three different facial recognition programs. They were as genetically unrelated as two random strangers would be on the street,. But they shared some very similar genes and some key places, especially like facial construction.
