When women are asked what they look for in a man, the answer usually is "sense of humor" or "animal lover," but the truth is there is something else, and it is pretty disturbing.
According to a study by the Journal of Human Behavior and Evolution Study, women want men who resemble their brothers.
Researchers had participants look at photos of men and rank them by how similar they were. Among the photos were pictures of women's brothers and the same women's boyfriends. The study showed "clear evidence for perceptual similarity in facial photographs of a woman's partner and her brother" meaning females tend to pair up with guys who look like their brothers.
According to the scientists, one possible reason for this is that familiarity is attractive - so in the same way you might like someone with similar interests, you'll like someone who resembles your brother.
