Because of the shortness of the Arabic language in scientific terms, we will use the term "human" to refer to the Sapiens and Humans to refer to Homo Sapiens.

In his book "Summary of Human History", the author speaks of the evolution of the human race and tells us the first stages of the evolution of the human race to our present time. His book ends with some scientific expectations for the future of human civilization.

The writer is looking for the reasons that humans survived alone among the rest of the human species from extinction, and why this group - alone among the other monkeys - dominated the planet and managed to dominate its resources.

Harari considers that the advantage of humans that outweigh other beings is their ability to communicate through ideas, not because they are real. Although many beings have developed communicative abilities, humans are the only species that have been created and continued with pure imagination. This has opened the way for the creation of legends of money, shared by all factions, facilitating cooperation between large groups of foreigners and strangers.

Harari considers that the history of mankind is divided into four fundamental revolutions.

The cognitive revolution.

1. Agricultural Revolution.
2. Scientific Revolution.
3. The Industrial Revolution.

1. Knowledge Revolution:

It began about 70 thousand years ago, when the wise man was able to develop his cognitive ability, which exceeded the ability of the other human beings in stages. This revolution allowed humans to dominate the earth, although our complex language was used for more chatter than for development. We began to create legends. From the belief and belief in the imagination that we have created ourselves, and allowed us to share the myths of collective cooperation and work in large numbers, previously were tribes, and today became States and nationalities.

.

2. Agricultural Revolution:

Began about 10 thousand years ago in the area between the Levant and western Iran and south-eastern Turkey, "Harari" that "the agricultural revolution is the biggest historical trick - the agricultural revolution was history of biggest fraud," a stage in which the wise man of planting plants and domestication Animals in groups.

The benefit of agriculture has been to increase the food resources of the cultivated area, which has allowed the population to multiply significantly, just like the modern-day accessories. Agriculture over time has become a necessary need to support the steady increase in population and nowhere to return.

3. Scientific Revolution:

Began about 500 years ago where the age of discoveries and modern science began, and many of the foundations of society today.

Before the scientific revolution was a Muslim that the religious books contain everything we need and content is real without controversy, while science has admitted that we do not know much, and even what we know can fall into the circle of error if it was revoked by a new evidence.

4. Industrial Revolution:

Began about 200 years ago and was complementary to the scientific revolution and its main reason the ability to convert energy to the movement and invention of electricity, which freed us from the natural cycle of day and night, winter and summer, and industrial agriculture to inflation in production and the emergence of capitalism, which prevailed because of human orientation towards the concept of consumption

The book urges reflection on the future. In recent decades, we have begun to bend the laws of natural selection that have governed life on the planet for four billion years. Our ability not only to dominate and redesign the world but to transform it today into ourselves.

What will these developments lead us to? What will we become later with these transformations?
