We watch as the Agricultural Revolution, the Scientific Revolution, imperialism, capitalism, and the Industrial Revolution change our species in lasting, and not always positive, ways. Along the way, we learn how our ability to create imagined realities led to our dominance over other species. Harari takes us on a journey that starts 2.5 million years ago, when Sapiens make their historical entrance, and ends in the future, when the creation of an artificially created superhuman race may mark the end of the Sapiens species. In Sapiens, Yuval Noah Harari uses concepts from biology, history, and economics to tell the story of us, Homo sapiens. Humans need something more-a shared belief system that helps them work with each other even though they don’t have constant one-on-one contact.

If the group is too large, personal communication isn’t enough to keep everyone working together toward a common goal. Humans and other animals like chimpanzees can’t form groups larger than about 50. The development of language made it easier for humans to share ideas with each other and collaborate on projects without being physically present at the same location. They could discuss things they’d never seen before, such as the supernatural or religion. This ability allowed them to communicate in new ways and tell stories that were not based on facts. Human beings developed language about 70,000 years ago. Part 1, Chapter 2: “The Tree of Knowledge” The most likely scenario is a combination of both theories. There are two theories about how we became dominant: interbreeding theory in which human species interbred until only one Homo sapiens remained and replacement theory in which human species fought each other for dominance. In this short period of time humans went from being insignificant to having a chance to eliminate natural selection altogether. During that time there were three major revolutions: cognitive, agricultural and scientific. Humans have evolved over the last 70,000 years.

This allowed us to develop larger brains that use 25 percent of our energy supplies this combination led to a rapid rise in power that disrupted the rest of the food chain as well as human development.

However, we began to hunt animals for food about 400,000 years ago and eventually became the top predators on Earth 100,000 years ago because we learned how to cook our food and digest it quickly through a shorter digestive tract. We were no more significant than any other animal or insect. Humans have evolved since the beginning of time. Part 1, Chapter 1: “An Animal of No Significance” Now we’re on the threshold of another revolution in human history because we’ve become like gods by transcending natural selection using genetic engineering and hastening the age of intelligent design. These ideas allow families to exist and flourish together. This is especially true when people are living in a community, but it’s also true for the billions of people on Earth who can interact peacefully because they have common ideas such as religion, empires, government, mathematics and writing. The concept of shared myths has helped humans cooperate with each other and unite. Therefore, it’s unclear how our species came to dominate the planet despite its many flaws and problems in today’s society. However, they also didn’t have technology or medical advances that help us live longer lives with less effort. They had more advantages that we don’t have now, such as a clear understanding of the world and what mattered most to them. Our ancestors were better off than we are. Finally, 200 years ago marked a revolution with industrialization that completely transformed Homo sapiens into what they are today. The Scientific Revolution brought about exploration, science, and capitalism 500 years ago. The Agricultural Revolution occurred 10,000 years ago and led to domestication of plants and animals. Humans developed cognitive abilities that surpassed other people during the Cognitive Revolution, which was 70,000 years ago. He also examined how humans have changed since the beginning and where we’re headed in the future. Harari began by describing the development of humans over time. It is particularly popular among academics because it was written by an academic. The book became a best-seller in America and won several awards. Israeli author Yuval Noah Harari’s book Sapiens: A Brief History of Humankind examines how humans have exploited capitalism, religion and politics to dominate the world. 1-Page Summary of Sapiens Overall Summary
