Join Annabelle & Aiden as their friend Lucy retraces our first steps in Africa. We fan across the globe, encountering the strangest human (and nonhuman) creatures: from twenty-foot sloths to tiny dwarves in faraway lands. We learn to cook. Express ourselves. Farm, build empires, and fall in love. We dream of kings, gods, and monsters, and light our world with a scientific revolution. Discover how our shared story can overcome our differences. How it's etched deep into genes: we're all children of Lucy, and have far more in common than we think.
