What does new research suggest about doppelgangers beyond physical similarities?

Recent research reveals that doppelgangers share more than just physical appearance - they may also have similar genetic profiles. According to a study published in Cell Reports, individuals identified as lookalikes often possess similar genotypes that influence both their physical features and behavioral traits. This surprising connection extends beyond mere facial resemblance, suggesting a biological foundation for why some unrelated people mirror each other so closely. The research, which examined 32 sets of doubles documented by Canadian artist Fran Noir Brunel, also found intriguing overlaps in lifestyle choices and educational backgrounds among these lookalikes, indicating genetics may influence more than just appearance.
