In the last decade, there has been an explosion of work investigating non-human species’ behavior as it relates to the human sense of fairness and justice. This research has provided a much needed evolutionary perspective on humans, and highlighted ways in which humans’ behavior is both similar to and different from that of other species. In this concluding paper, we outline the major threads of the work highlighted in this and the previous special issues of Social Justice Research and provide thoughts on future directions for the field. This is a very exciting time in our exploration of the evolution of human justice and fairness, and we eagerly await the developments of the next decade.
