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.

In the Middle Stone Age, change happened everywhere, but at different times in different places.

The first known plague victim dates from this era, and so do the earliest temples. Each chapter includes attention-grabbing photos and fascinating facts.
