Sapiens: A Brief History of Humankind, by Yuval Noah Harari

Review by Melanie Holmes

In Sapiens: A Brief History of Humankind, Yuval Noah Harari asks the question: Will the three major historical revolutions that have shaped the world we see today bring about the end of the species we call Homo sapiens? As Harari contemplates this question, he takes us on a “brief” 13.5 billion year tour of physics, biology, politics, religion, culture, and science. In four major parts, he does so in a way that ensures readers won’t get lost.

The Cognitive Revolution

Harari starts us out two and a half million years ago when Sapiens existed as just one of many species in the genus Homo that existed in different parts of the world. As he continues on the timeline, he astutely examines how things changed 70,000 years ago with the advent of the Cognitive Revolution. Harari gives a fascinating account of how the development of sophisticated language created collective belief systems, “cultures” and/or “shared myths,” and why extinction of many species followed. While Sapiens’ flood into new lands brought about this “First Wave Extinction,” Harari also walks us through Sapiens’ switch from foraging to farming as a way of life, and how this switch brought about the “Second Wave Extinction.”

The Agricultural Revolution

In Part Two, Harari delves into why the Agricultural Revolution exposes “history’s biggest fraud” and its many voiceless victims; and how it resulted in a population explosion of humans that continues today. He unravels how history set in stone (literally) the first unjust laws that divided humans along the lines of class and gender in order to serve “the few.” Even with such divisions, Harari gives an interesting examination of how rulers sought to unite humankind.

The Unification of Humankind

From the imperial ideology of Cyrus the Great of Persia (550 B.C.) to the inexorable march to “enlighten the barbarians,” in Part Three, Harari shows how commerce, empires, and universal religions eventually drew Sapiens on every continent into the global world we live in today. Through these movements, we learn how the world has evolved from many small cultures to a few large cultures, and finally to a single global society. As Harari ponders whether history has unified humans in a way that is “best,” he makes a crucial case for studying history—to understand that our present situation isn’t necessarily “natural.”

The Scientific Revolution

As rulers saw new knowledge as a path to becoming masters of the world, the third historic revolution fueled expeditions to new continents. Harari tells sad tales of how some of these expeditions turned into genocide and many civilizations disappeared. He makes us look at how on one hand, empires, with their technological improvements and accomplishments, have made life easier for humans. Yet the means by which those accomplishments were achieved resulted in a long list of crimes against humanity, and the plundering of many other of Earth’s life forms.

Harari brings together various disciplines as only a historian can, and asks: Did all the progress/advancements make things better? And if so, for whom? Also, what will it mean when science “tinkers with our genes” to the point that the definition of what it means to be human changes forever?

Given a Choice…

In reading this book, I cried when I read about calves on a modern meat farm, separated from their mothers at birth, crammed into small stalls, who take their first long walk en route to the slaughterhouse. And I laughed at matriarchal bonobo chimpanzees with all-female social networks who gang up on uncooperative males to keep them in line. If given a choice between reading a tome on the scientific developments over the past century, a book on world politics, or a summary of the world’s religions, I would choose Harari’s book. It incorporates physics, chemistry, biology, religion, culture, geography, economics, and the ethics of domesticating a select number of living things for the advantage of one animal—Sapiens.
