So, scientists have officially told us what catty adolescent and college-age girls have known for years: Women are copycats (ha!) when it comes to the men they choose to date. 

A study conducted by British scientists concluded that "when sizing up a man, a woman takes her cues from other women around him." Basically, you might not think that shaggy-haired junior in control of the keg is much of a catch – until you see a bunch of other girls flirting with him.

The whole idea relates to back to a Darwinian principle of evolution, that if a female has a hard time finding a mate, she looks to rival females to observe how she should behave. 

This isn't rocket science, and honestly, I could've made this conclusion as soon as I set foot in high school. But next time you find yourself lusting after your good friend's beau, you can blame it on human nature.
