| We're the smartest animal in the world. Fact. But, the human brain isn't the largest in the world. Fact. Nor do we have the largest number of neurons. Fact. So what explains our intelligence? This TED Talk dives deep into neuroscience and evolutionary theory and draws the conclusion that our extraordinarily, even bizarrely, dense cerebral cortex uses the most energy for its weight in the animal kingdom. And the only way to release all of that energy from food is through developing the ability to cook. The IB Biological Level of Analysis asks you to "Examine one evolutionary explanation of behaviour." Can you make the link? |
