Whatever deep meaning we are looking for in life, nature has its own answer to this question: the continuation of life. But how do we manage to adapt for so many thousands of years and find new ways to survive in the process of evolution? Humanity has an answer to this question: intelligence is probably the pinnacle of adaptation of a living being to nature. But how does this truly cosmic scale object function? Together with journalists from the Nauka TV channel, Alexander Kaplan tried to solve the mystery of the human brain. In this book, leading Russian neuroscientists, linguists, anthropologists, paleontologists, biochemists and evolutionary biologists express their opinions on the structure and evolution of the human brain.
