Question

What is the evolutionary aspect behind crying? Simply, why have we adapted to crying when we are sad?

Answer

Crying is a bit of a mystery, but there's an argument that crying serves as a visible signal of our feelings to others ... and signally your feelings would help bring the social group together, in that they would be more likely to empathize with you. Not totally convinced by this. Crying is as mysterious as the contagiousness of yawning.
