Background knowledge to deeply understand ‘Sapiens: A Brief History of Humankind’ by Yuval Noah Harari
**1. Basic understanding of evolutionary biology and the timeline of life on Earth**
Harari’s book begins with the appearance of Homo sapiens and traces its journey to become the dominant species on the planet. Understanding the basics of evolutionary biology, including concepts like natural selection, adaptation, and speciation, is crucial for grasping how humans evolved from earlier hominids and how they interacted with other species. A basic understanding of the geological timescale and the major eras of life on Earth (Paleozoic, Mesozoic, Cenozoic) helps contextualize the emergence of humans within the broader history of life. Key events like the Cambrian explosion, the Permian extinction, and the rise and fall of dinosaurs provide a backdrop for understanding the conditions under which humans evolved.
**2. Familiarity with different hominid species and their characteristics**
Sapiens were not the only human species to have existed. Harari discusses several other hominid species like Neanderthals, Denisovans, and Homo erectus that coexisted with Sapiens at various points in time. Having a basic understanding of these different species, their physical characteristics, geographical distribution, and cultural practices (if any evidence exists) is helpful in understanding the complex interactions between human species and the eventual triumph of Sapiens. Resources like the Smithsonian National Museum of Natural History’s Human Origins Program provide detailed information on various hominid species.
**3. Knowledge of the Cognitive Revolution and its implications**
One of the central arguments in Sapiens is the importance of the Cognitive Revolution, a period around 70,000 years ago when Sapiens underwent a significant leap in cognitive abilities. This revolution enabled Sapiens to develop complex language, abstract thought, and the ability to cooperate in larger groups. Understanding the potential causes of the Cognitive Revolution, its impact on human behavior, and its role in the development of culture and technology is crucial for understanding Harari’s narrative. This includes exploring theories related to genetic mutations, changes in brain structure, and the development of symbolic thinking.
**4. Understanding of the Agricultural Revolution and its consequences**
Harari argues that the Agricultural Revolution, which began around 10,000 years ago, was a pivotal moment in human history, but not necessarily a positive one. He discusses how the shift from a hunter-gatherer lifestyle to settled agriculture led to significant changes in human societies, including population growth, the rise of cities, the development of social hierarchies, and increased workload and disease. Understanding the pros and cons of the Agricultural Revolution, its impact on human health and well-being, and its role in shaping subsequent historical developments is crucial for appreciating Harari’s perspective.
**5. Basic knowledge of major historical empires and civilizations**
Harari’s narrative covers a vast sweep of human history, from the ancient empires of Mesopotamia and Egypt to the modern nation-states. Having a basic understanding of major historical empires and civilizations, their rise and fall, their political and economic systems, and their cultural achievements, provides a framework for understanding the broader historical context of Sapiens’ journey. This includes understanding the development of writing systems, the spread of religions, the growth of trade networks, and the emergence of different forms of government.
**6. Familiarity with concepts like money, empires, and religion**
Harari explores how certain “imagined orders” like money, empires, and religion have played a crucial role in shaping human societies and enabling large-scale cooperation. Understanding the nature of these imagined realities, how they emerged and evolved, and their impact on human behavior and social structures is central to understanding Harari’s arguments. This includes exploring the psychological and sociological mechanisms that allow humans to believe in and adhere to shared fictions and the consequences of these shared beliefs.
**7. Basic understanding of the Scientific Revolution and its impact**
Harari discusses the Scientific Revolution, which began in the 16th century, as a major turning point in human history. He explores how the development of the scientific method, the emphasis on empirical observation and experimentation, and the growing understanding of the natural world led to unprecedented technological advancements and transformed human societies. Understanding the key figures and ideas of the Scientific Revolution, its relationship with other historical developments like the Enlightenment and the Industrial Revolution, and its impact on human knowledge and power is important for understanding Harari’s narrative.
**8. Awareness of contemporary issues like globalization, capitalism, and bioengineering**
Harari concludes his book by discussing the challenges and opportunities facing humanity in the 21st century, including globalization, capitalism, and the rise of bioengineering and artificial intelligence. Having an awareness of these contemporary issues, their potential impact on human societies, and the ethical dilemmas they raise is essential for engaging with Harari’s concluding reflections on the future of humankind. This includes exploring different perspectives on these issues and considering the potential long-term consequences of current trends.
**9. Openness to interdisciplinary perspectives**
Harari’s book draws on insights from a wide range of disciplines, including history, biology, anthropology, psychology, economics, and philosophy. Being open to considering different perspectives and integrating knowledge from various fields is crucial for fully appreciating the scope and depth of Harari’s analysis. This includes recognizing the limitations of any single disciplinary approach and being willing to consider alternative explanations and interpretations.
