These periods of history are known after the newly discovered/popular material – stone, bronze and iron.
This is because that particular material was easily worked or easy to get to, this is why stone comes first. As the people become more intelligent and experienced they move to things like metal. Bronze came before iron because the two metals that are needed to make bronze, copper and tin were readily available. iron is a lot stronger but harder to mine, smelt and work – so people needed more efficient fires for smelting because iron needs a much higher heat than copper and tin to smelt and work.
