Little attention has been paid to competitive dynamics from a political perspective, despite numerous instances of political competition across cultures and systems. In liberal democratic societies, political competition is legalized, allowing citizens to elect leaders who represent their ideas. Conversely, in totalitarian societies, citizens lack voting rights, and political authority is not challenged through democratic means. However, political competitions still occur among ruling elites, often through purges to seize power. This chapter explores political competition, particularly in totalitarian regimes, where purges eliminate rivals among ruling elites. The collapse of such regimes has marked an evolution toward freedom and equal opportunities for all individuals, regardless of background, which aligns with Darwin’s theory of evolution. Highlighting the lack of research on political competitions from an evolutionary psychology perspective, this chapter underscores the need for future research on human emotions and competitive behaviors in the political arena.

China’s property law framework is underpinned by a series of fundamental laws and statutory reforms that define the ownership, usage and transfer of both urban and rural property. These statutes not only reflect the evolution of property law in China but also highlight the country’s ongoing efforts to balance state control with private property rights, aiming to foster economic development while ensuring social stability and equity. The dynamic nature of China’s property law framework continues to evolve in response to domestic and international economic pressures, requiring continuous analysis and adaptation. Notwithstanding the ongoing signs of progress, Chinese property law faces several challenges that stem from rapid economic development, urbanization, ideological inertia and the legal complexities of transitioning to a market-oriented economy. Rather than a linear transition to private ownership, China’s institutional reform of rural land markets is more complex than orthodoxy economic theory, law and development theory suggests.

Chapter 3 explores open quantum systems, emphasizing their interactions with environments, unlike isolated closed systems. It introduces the concept of generalized measurements and mixed quantum states, reflecting the complex scenarios arising from these interactions. The chapter utilizes Positive Operator Valued Measures (POVMs) to describe generalized measurements, broadening the conventional approach to quantum measurements.

A significant focus is on the evolution of open systems through quantum channels, which illustrate the transfer or transformation of quantum information amid noise and external disturbances. This section underpins the dynamics open systems exhibit, critical for understanding quantum computing and information processing in realistic settings.

Through practical examples, the chapter elucidates how environmental factors influence quantum information, vital for applications in quantum technologies. It aims to equip readers with foundational knowledge of open quantum systems, highlighting their importance in the broader context of quantum mechanics.

Chapter 11 deals with the timescale of history and human evolution. It offers a complexity approach to the evolution of art that attempts to move beyond simplistic theories of the survival function of art, including the much-debated issue of the function of art in the context of sexual selection. After discussing the basic principles of evolution from a complex systems approach, the chapter outlines different evolutionary scenarios: the survival-enhancing function, on the one hand, and the view of art as an evolutionary by-product, on the other. By showing how both evolution and human activity are entangled, interaction-dominated dynamics, the chapter provides an alternative to simplistic gene-for-art assumptions.

This chapter of the handbook examines the complex relation between empathy and prosociality by drawing on evolutionary theory, neuroscience, psychology, and behavioral economics. The author begins by distinguishing three components of the broader phenomenon of empathy: emotional contagion, empathic concern, and perspective taking. He reviews evidence suggesting that emotional contagion of a conspecific’s pain often leads to helping behavior, but such contagion is modulated by group membership, levels of intimacy, and attitudes toward the other. Empathic concern, too, is a powerful motivator of prosocial behaviors but is also socially modulated – extended to some people more than others and to individuals more than groups. Effortful perspective taking, finally, can provide a better understanding of other people’s minds but does not always generate prosocial behavior, even when it facilitates empathic concern. In sum, various forms of empathy can motivate prosocial behaviors, but empathy is fragile and often stops short of its potential when people engage with large groups, people outside of their tribe, or anonymous strangers.

This chapter of the handbook proposes a developmental ethics, an organic moral theory grounded in (1) humanity’s deep evolutionary history, (2) the malleability of the child’s neurobiological structures that undergird moral functioning, and (3) the influence of cultural practices on neurobiological development. The chapter addresses the following questions: What kind of creature are we? What qualities do we need to live a full life? What kinds of capacities make each a proper member of the species? What influences our development? Answers center around perhaps the most critical influence on human development, our species’ evolved nest. In humanity’s ancestral context, nestedness is a lifelong experience with particular import in early life. Moral virtue emerges from holistically coordinated physiological, psychological, spiritual systems oriented toward holistic communal harmony, social attunement, receptivity, and interpersonal flexibility. Understanding how the evolved nest scaffolds biopsychosocial and moral development reveals why antisocial behavior is so pervasive in modern Western culture – and it provides a baseline for redesigning society to promote prosociality.

My biographical sketch describes how I became a cultural/cross-cultural developmental scientist as a complete autodidact. During the late 1960s in Germany universities were in a massive process of change which only later resulted in formal institutional structures and curricula. Until then, there was complete freedom for pursuing interests and selecting topics. I was generally interested in other cultures and found opportunities to study children and families abroad. Connecting with evolutionary theory prompted me towards being a universalist. In another direction, meeting great minds in the fields of cultural and cross-cultural psychology helped me find my point of view as a developmental scientist studying children’s developmental pathways in different cultural environments. Together with wonderful colleagues, I studied systematic contextual variations in solving general developmental tasks. My overall conclusion is that culture needs to be consistently introduced into developmental science and all its applications (in policy and practical interventions).
