  • Bronze Age – The evolving ability of man to work with metal gave the ability to form stronger tools, and the introduction of the wheel allowed people greater ability to travel and communicate.
  • Iron Age – The ability to work with harder metals than copper and tin, to smelt iron, and to be able to remove iron from ore allowed for rapid increases in weapons making, brought the development of tools that benefit civilization and gave greater ability to perform tasks, such as manufacturing and transportation.
  • Computers and the Internet – The ability to perform basic thinking processes much faster enables business, science and commerce to proceed much more efficiently.
