"What was life on earth like two million years ago? A thousand years ago? The years in between? When did people start wearing clothes? When did farming begin, and how did that change things? This series takes you back to the time of the earliest humans. The dinosaurs were long gone, but the world was still strange and wild."--Back cover
In the final stage of the Stone Age, humans' use of stone tools was coming to an end. People started farming, at different times in different places. Chapters cover how plants and animals were domesticated, how pottery production boomed, and how farming meant that people could settle down, stay put, and build great cities like Jericho. The first known plague victim dates from this era, and so do the earliest temples. Each chapter includes attention-grabbing photos and fascinating facts. Sidebars go deeper, and prompts invite readers to think for themselves. A Timeline of the Neolithic Era gives a big-picture view.
The Old Stone Age was the time of the earliest humans. Chapters cover how these early people left Africa and spread around the world, how they made tools to solve life's problems, and the role of Paleolithic women, who probably did a lot more than stay home and care for the kids. Each chapter includes attention-grabbing photos and fascinating facts. Sidebars go deeper, and prompts invite readers to think for themselves. A Timeline of the Paleolithic Era gives a big-picture view.
Exposes 12 of the most enduring myths about the Earth. Full-color spreads give readers essential information about each myth, including why it exists, the key players who proved it wrong, and what the truth really is.
The Bronze Age was a time of growth. Chapters cover how people used bronze to make tools and weapons, how empires grew in Mesopotamia and China, how writing appeared in several cultures, how complex social structures gave rise to rules and laws, and how religion, science, and medicine all grew. Then the Bronze Age collapsed, and researchers still don't know exactly what happened. Each chapter includes attention-grabbing photos and fascinating facts. Sidebars go deeper, and prompts invite readers to think for themselves. A Timeline of the Bronze Age gives a big-picture view of the era.
