Aristotle's Politics provides an example of what a biopolitical science might look like. Three key elements stand out: (1) an account of political structure as a multilevel society including kin and non-kin relationships; (2) an account of the human species that includes comparison with other social species that are capable of coordinated action; and (3) an emphasis on the human capacity to understand and communicate moral rules. Over the last 50 years, a number of research programs in evolutionary anthropology have provided the basis for a biopolitical science that maps onto the elements above. Schultz, Opie, and Atkinson describe the trajectory of human evolution from solitary to a pair bonded, familial species. Michael Tomasello's two-step account of the evolution of human cooperation shows how the ancestral humans went from merely gregarious to genuinely political animals. Christopher Boehm shows how the human capacity for moral emotions and decision making by consensus developed. Richard Wrangham provides evidence that the suppression of reactive aggression by ancestral human societies resulted in a self-domesticated species, a process that enhanced the human capacity for cooperation and communication. Bernard Chapais argued that the emergence of pair bonding among ancestral humans laid the foundation for both consanguineal and affinal kinship structures. That these bodies of research hold together can best be seen when they are viewed in light of Aristotle's biopolitical science.

The age diversity climate construct is gaining greater attention in the organizational literature due to the demographic changes in the workplace. While the few existing studies on age diversity climate (ADC) are rather encouraging, this construct is still at an early stage of conceptual and operational development. This chapter helps to advance this field of research by analyzing the conceptual issues stemming from the theoretical definition and empirical measurement of the ADC construct. We first review and compare ADC with other age-focused climate concepts, highlighting overlapping and diverging factors regarding their conceptual framework and operationalization. Subsequently, we consider several open issues related to the operationalization of ADC, including the level of analysis, the choice of referent, and the dimensions of analysis. We conclude the chapter by outlining possibilities for future research on ADC.

Over the past decade, the U.S. workforce has become increasingly diverse. In response, scholars and practitioners have sought to uncover ways to leverage this increasing diversity to enhance business performance. To date, research evidence has failed to provide consistent support for the value of diversity to organizational effectiveness. Accordingly, scholars have shifted their attention to diversity management as a means to fully realize the potential benefits of diversity in organizations. The principal aim of this chapter is to review the current wisdom on the study of diversity climate in organizations. Defined as the extent that employees view an organization as utilizing fair personnel practices and socially integrating all personnel into the work environment, diversity climate has been proposed as a catalyst for unlocking the full value of diversity in organizations. During our review, we discuss the existent individual- and aggregate-level research, describe the theoretical foundations of such work, summarize the key research findings and themes gleaned from work in each domain, and note the limitations of diversity climate research. Finally, we highlight the domains of uncertainty regarding diversity climate research, and offer recommendations for future work that can enhance knowledge of diversity climate effects on organizational outcomes.

Politics in human societies represents a variation, and elaboration, on a major evolutionary theme. Political processes have played an important functional role in goal-oriented, cooperative social systems in the natural world. This view of politics is also consistent with a causal theory – known as the Synergism Hypothesis – which explains the rise of complexity in evolution over time and, equally important, the frequent examples of devolution and dissolution. In addition to a brief discussion of this theory, the evolution of political systems in humankind will be described, from its possible origins among our remote australopithecine ancestors to the emergence of complex modern civilizations. Now, however, we confront an existential threat to our species, and to many others, due mainly to climate change. The future is very problematic. I will argue here that the only viable path going forward is a new social contract coupled with (democratic) global governance – a global “superorganism.”
