Like all evolutionary psychology you can argue forever about the 'adaptive value' of any behaviour and characteristic and never know whether what you're saying is true or just completely and utterly wrong. It has a reputation for a reason. I could make a list full of hundreds of reasons why depression might be adaptive - that it's so darn easy should serve as a warning why it's often a bad idea to theorise like this.
