I've heard it said more than once that everyone has an evil twin out there somwhere.
By "evil twin" I mean someone who is non-genetically related but bears a striking, (I realize that term is subjective but try to work with me) if not identical resemblance to ourselves. Of course, they don't necessarily have to be evil.
For fun, websites like this are using facial recognition software to compare the faces of their users to those of celebrities.
- What is the likelihood of two random, unrelated people sharing identical features? Has anyone studied this?
- Have there been documented cases of this occurring?
