Tenets

Common attachment behaviors and emotions, displayed in most social primates including humans, are adaptive. The long-term evolution of these species has involved selection for social behaviours that make individual or group survival more likely. The commonly observed attachment behavior of toddlers staying near familiar people would have had safety advantages in the environment of early adaptation and has similar advantages today. Bowlby saw the environment of early adaptation as similar to current hunter-gatherer societies. There is a survival advantage in the capacity to sense possibly dangerous conditions such as unfamiliarity, being alone, or rapid approach. According to Bowlby, proximity-seeking to the attachment figure in the face of threat is the "set-goal" of the attachment behavioral system.
