Sample Book Insights: #1 We had a very ancient ancestor that was very similar to a modern-day amphioxus. They inhabited the oceans about 550 million years ago. They had no brains, but they had senses like yours and could sense changes in light. #2 The emergence of predators during the Cambrian period transformed the planet into a more competitive and dangerous place. Creatures that could sense their surroundings and move efficiently were more likely to survive and thrive. #3 Allostasis is the process by which an animal prepares itself for a predicted event. It is the brain's ability to predict and prepare for the body's needs before they arise. #4 Your brain's most important job is to manage your body budget and keep you alive by predicting energy needs before you make decisions. Everything your brain creates is part of this mission.
