Understand what makes us human! Unleash Your Primal Brain is about the commonalities all 8,000,000,000 people on earth share. Our ancestors were molded by ruthless survival pressures from the earliest days of life on the planet. Adaptations which worked long ago are still inside of us - also shared with insects and reptiles. Later additions are common to all mammals from the tiniest shrews to the most massive whales. Some capabilities were bolted on relatively recently and are only shared with our primate cousins. And the runaway explosion of humans on the planet can only be explained by our own bizarre species-level evolution. The only way to understand how our brains work is to examine the complete evolutionary arc.
