The Stone Age
The Stone Age started around 2.5 million years ago when early humans first produced the first stone tools. The Stone Age is split into three different parts: the Paleolithic (Old Stone Age), the Mesolithic (Middle Stone Age), and the Neolithic (New Stone Age).
During the Old Stone Age, humans evolved from Neanderthals and other groups into modern humans. People survived by gathering wild nuts, fruits, and berries. They also hunted wild animals. The tradition is that women did the gathering and men did the hunting. When the food ran out, these hunter-gatherers moved on.
The Middle Stone Age began at the end of the last Ice Age when sea levels rose and Britain became an island. In the New Stone Age, the way people lived changed significantly. People began building settlements instead of moving from place to place. They built walls around their settlements to protect themselves and started to grow their own crops and domesticate animals. Tools for grinding, cutting, and chopping were also introduced. People used bones for fishhooks so that they could catch fish as well as animals.
