Please note: This is a companion version & not the original book. Sample Book Insights:#1 Humans are the most intelligent beings on the planet, but we are also the most arrogant. Our intelligence falls short of reminding us of the truth that we may not know everything or be able to solve every problem.#2 The definition of intelligence is subjective. It can be used to learn new things, deal with new situations, and apply knowledge to manipulate your environment. It is often attributed to beings that possess it.#3 The human brain has evolved gradually over the passage of time. It is still true today that you can develop the parts of your brain that you train. The most important thing for developing intelligence is communication, which has helped us preserve the knowledge, learning, discoveries, and intelligence we have gained and pass them on from person to person.#4 Our intelligence as a species evolved. We all became smarter than our ancestors, and some of us became smarter than others. The intelligence of other species, such as the great ape or the chimpanzee, did not keep up with us.
