The cognitive revolution introduced new ways of thinking and communicating. An accidental mutation altered the inner wiring of the brain enabling these new ways to interact among one another (Harari p.21). This gave homo sapiens the ability to imagine new worlds and ideas and eventually form imagined orders which have been relevant since. By introducing the concept of growing food, the agricultural revolution sparked a new way of life for homo sapiens. This encouraged people to to create stationary societies opposed to the nomadic way of life.
Homo sapiens became so dominant as a result of our abnormally sized brains. Our brains gave us the skills and reason to develop as the premier species in todays world. Homo sapiens have overtime created an inter-subjective (Harari p.116) order that exists in the shared imagination within us. This would be called imagined orders. I think that imagined orders have created a social structure within societies around the world. These structures include but are not limited to religion, government, and money. The concept of money is quite fascinating if you think about it. You take something without any inherent value such as paper and you create a story behind it to make it a desired aspect of life. By having these imagined orders in our society it gave us more inspiration in life opposed to simply surviving. Also a part of homo sapiens thriving as a species has to do with the domestication of fire. Fire gave us the ability to cook, stay warm, and protect ourselves against predators which ultimately led to survival. Harari’s arguments were valid because they were backed by reason and scientific facts. Homo sapiens became dominant because our their ability to interact with each other and therefore exchange ideas on all aspects of life.
