The most fit will survive to reproduce, passing on their genes to the next generation. This, of course, is Darwin's theory of natural selection. An individual pursues the most genetically fit partner to pass on favorable traits to offspring, increasing their chance of reproductive success.

But it is 2011, and with hair gel and a dearth of natural predators, humans function outside of these bounds. Fathers do not hunt for food, and mothers do not fight off tigers. The act of survival simply is not that difficult — most everyone lives to reproductive age. So how do humans choose a mate?

Natalie Villacorta at the The Brown Daily Herald has the answers.
