About 1.7 million years ago we see evidence of a new technology for manufacturing stone tool. Called the Acheulean, it was an industry of symmetrical tools, and it indicates the preconception of a desired form.

The earliest human ancestors outside Africa show up at 1.8 million years ago, and are referred to by most as early Homo erectus or Homo erectus ergaster
