Evolution of Human Aggression and Morality
Humans exhibit unique capacities for both benevolence and aggression, with a capacity for extreme ruthlessness. The evolutionary story of human aggression reveals a mix of aggressive and tolerant behaviors being inherent to our biology, rather than solely a result of societal influences. Dr. Richard Rangam discusses the concept of humans selectively breeding themselves to become less aggressive over time, leading to the coexistence of aggressive and kind tendencies in our species.
Development of Human Aggression and Self-Domestication
Over the last two million years, humans developed hunting and killing abilities that could be turned inward, leading to intergroup rivalries and coalitional killings. Around 300,000 years ago, the development of advanced language allowed groups to coordinate efficiently, enabling the execution of tyrannical individuals within the group. This process of self-domestication, through the collective removal of aggressive members, contributed to reducing reactive aggression in humans over time.
Impact of Power Dynamics on Morality
The emergence of power dynamics within human groups, notably the Alpha Alliance capable of executing individuals, coincided with the evolution of moral principles based on concepts of right and wrong. Humans formulated moral codes that benefited the group as a whole and the dominance of the men within the group. This morality stemmed from evolutionary pressures to conform to survival strategies and avoid punishment, highlighting the impact of power dynamics on the development of human morality.
Bonobos vs. Chimpanzees: Contrasting Aggression and Social Dynamics
Bonobos exhibit less proactive aggression compared to chimpanzees, suggesting selection against such behavior in bonobos. The female-led, coalitionary self-domestication route in bonobos is unique, aiming to prevent males from being aggressive towards females. In bonobos, when a male challenges a female, females come to her aid against the male, highlighting a shift in social dynamics towards female protection.
Evolution of Morality and Male Power Dynamics
The narrator delves into the concept of morality being shaped by what benefits male groups historically. The podcast explores how male roles are changing in modern society, with women achieving more independence economically and socially. Discussions touch on the evolving nature of aggression, the role of fathers in raising sons, and the potential future where reproduction may not require males, prompting reflections on the future role and relevance of males in society.
Dr Richard Wrangham is an anthropologist and primatologist, a Professor of Biological Anthropology at Harvard University and an author whose research focuses on ape behaviour, human evolution, violence, and cooking.
Humans have the capacity for incredible benevolence and kindness, but also are able to be execute other members of our species with a uniquely effective ruthlessness. Why would evolution give us such differing capacities to chimps and apes and what can this tell us about our nature?
Expect to learn the fascinating evolutionary story of human aggression through the ages, how humans actually selectively bred ourselves to become less aggressive, how our capacity for violence informed the evolution of morality, the true reason for why humans might have a sense of right and wrong, what would have happened to a hyper aggressive male ancestrally and much more...
