Copper Age

The Copper Age succeeds the Neolithic Era of the Stone Age, and precedes the Bronze Age. During the Copper Age, humans gain the ability to extract and use the mineral when constructing tools and weapons on a relatively large production scale. Drier climate of the period also encourages innovation from basic crop farming to expansion of animal domestication.

Mass-scale mining of the previous era allows for metalworking technology in this age, predominantly in copper.

Mammoths and Woolly Rhinos become extinct with the opening of the Copper Age, shortly after you have acquired Copper Smelting.
