Answer by Carissa Bruno:
In the DBT (dialectical-behavioral therapy) model developed by Marsha Linehan, emotions are cited as serving three primary purposes: motivation, communication, and self-validation. The first two are most approachable from an evolutionary perspective. Sadness, or any avoidance-driving emotion like anger or fear, can motivate one to alter one's environment to be more conducive to thriving. Secondly, because humans are social animals, exhibiting signs of distress associated with sadness can communicate to others that a person is in need of assistance.
