It's very important first to understand that evolutionary processes do not have a causative role in all evolved behaviors or traits. Often species responses to various stimuli are simply that responses to either stimuli in presence or absence and not a behavior that has evolutionary causation. Grief is a perfect example of such a response. It is a reaction to the end of a continuous stream of signals that otherwise would come from an individuals (or items) presence and represents a momentary set of *shocks* at the re-realization at the loss when need presents. "Need" can be as simple as the desire to talk to a person who is gone or hear their laughter. Unlike the things we surround ourselves with...which we experience sensorially only in a limited band of ways (and thus impress networks in our brain in an equally limited way) The influence of individuals we've been close to on our brain networks is extensive...especially when those histories go back to childhoo...

The revolution is being accelerated by an additional recent factor about our ability to survive on this planet that is due to our ability now to directly modulate the genetic information of living beings without risk of cancer.
