What similarities do doppelgangers share beyond physical appearance?

According to the study mentioned in the podcast, doppelgangers share remarkable similarities that extend far beyond physical appearance. These lookalikes were found to have similar levels of education, height, weight, and even smoking history, suggesting deeper connections than mere coincidental resemblance. The research, published in Cell Reports by Manel Estella and colleagues, examined 32 pairs of 'virtual twins' using advanced facial recognition software and comprehensive DNA testing. The findings revealed that these doppelgangers possess shared genetic variants that influence both their appearance and behavioral traits, highlighting the fascinating intersection of genetics, epigenetics, and environmental factors in human resemblance.
