At least, it definitely seriously shocked me when I read that a French research team at the Institut des Sciences de l'Evolution de Montpellier printed in MedicalXpress that homogamy (a relationship between two individuals who share the same qualities) plays a LARGE role in how men choose their women.

Apparently, according to the study, 37 percent of men "picked the face which shared the most features with theirs" and researchers also analyzed photographs of real-life couples and found that "each one shared more facial traits than two random individuals would," according to Jezebel.com. Basically, it turns out that men like women who look just like them!
