Here's another excuse to allow men to be pervy..

Researchers from England and Netherlands scanned some brains of men and women and discovered men pick their partners based on how attractive a woman looks because it is an automatic response to how fertile a woman is. It's an ancient explanation and very animalistic result if you think about it.

Women however take longer to evaluate their potential partners, weighing in stability, security and future survival abilities. *whee, smart!

While the subjects were doing the task they were shown a series of photographs of faces of the opposite sex, ranging from attractive to ugly.

Men were easily distracted when they saw a pretty face but women stuck to the task.

Prof van Vugt said: "Men definitely have the most wandering eye but it is because they have evolved to pay attention to cues of fertility and one of those cues is facial beauty – it's not that men are shallow.

Are they saying men really can't help avoiding you (as a potential partner) if you're ugly and can't score a date. Ouch! Cue lesbianism?
