Human Brain Evolution

Sharing stories and advice rooted in the science of evolutionary psychology, father and son authors Doug Kenrick and David Lundberg-Kenrick pinpoint the dangers of stone-age problem solving for our lives today, and present a new, systematic way to survive and be happy in the modern world.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. What saved us during that period of endangerment? The...

John Parrington draws on the latest research on the human brain to show how it differs strikingly from those of other animals in its structure and function at a molecular and cellular level. And he argues that this 'shift', enlarging the brain, giving it greater flexibility and enabling higher functions such as imagination, was driven by tool use, but especially by the development of one remarkable tool - language.

In this book, E. Fuller Torrey draws on cutting-edge neuroscience research to propose a startling answer to the ultimate question. Evolving Brains, Emerging Gods locates the origin of gods within the human brain, arguing that religious belief is a by-product of evolution. Based on an idea originally proposed by Charles Darwin, Torrey marshals evidence that the emergence of gods was an incidental consequence of several evolutionary factors.

Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25 percent of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals but not because we are evolutionary outliers.

Many of us know people whom society and doctors would consider personality disordered or mentally ill. We often use these labels for diagnoses and treatment. Sometimes the labels aren't accurate due to difficulties in testing for disorders and due to the differing views of the physicians and psychoanalysts. But are these people really disordered after all? Is there truly a normal personality that exists, and if it does exist - what is it?
