The Stone Age, the Bronze Age, and the Iron Age are three period of history identified by the way people made tools and weapons. Different ancient civilizations developed at different speeds. So you might have one group of early people using bronze tools, while another group was still using stone tools. Those with better tools had a much easier time conquering other groups of people. The material used to make tool and weapons most definitely had an influence on daily life in ancient times.
Very Early Humans lived in the Stone Age. To survive, early humans invented and created stone and bone weapons and tools. With these tools, early humans could kill and trap those animals they needed for food. With stone axes and spears, they could defend against those animals that thought they were food. Tools made of bones, shells, and stones all fall under Stone Age tools ecause they are not made of metal. The Stone Age is considered to have begun about two million years ago, and ended sometime after the end of the last ice age, about ten thousand years ago.
