Human Brain Evolution

Equal parts Sapiens, Behave, and Superintelligence, but wholly original in scope, A Brief History of Intelligence offers a paradigm shift for how we understand neuroscience and AI. Artificial intelligence entrepreneur Max Bennett chronicles the five “breakthroughs” in the evolution of human intelligence and reveals what brains of the past can tell us about the AI of tomorrow.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

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.

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. The human brain, and its evolutionary journey, is unlike anything else in history. In A History of the Human Brain, Bret Stetka takes listeners through that far-reaching journey. He also tackles the question of where the brain will take us next, exploring the burgeoning con­cepts of epigenetics and new technologies like CRISPR.

We’ve come a long way. The earliest human had a brain as small as a child’s fist; ours are four times bigger, with spectacular abilities and potential we are only just beginning to understand. This is How the Mind Changed, a seven-million-year journey through our own heads, packed with vivid stories, groundbreaking science, and thrilling surprises. Discover how memory has almost nothing to do with the past.

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.

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.

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?
