The Venus of Lespegue from France (left) and the Venus of Willendorf from Austria (right) date from the same time period, yet their artistic styles reflect the distinct cultures of these two different Paleolithic societies. Venus of Willendorf photo by Matthias Kabel, Creative Commons.



This cuneiform letter, written with a wedge-shaped stylus in soft clay, was sent to the king of the Mesopotamian city of Lagash, informing him of the death of his son in combat.  


Writing began in the Indus Valley with symbols carved onto clay seals (A) often combined with imagery (B) and stamped onto soft clay or wax (C). The use of repeated symbols (D) is evidence that the Indus script was a true written language.

The global population of human hunters and gatherers stood at roughly five million people in 5000 BC and grew to 150 million over the next five thousand years. But when the industrial revolution began in 1800, the human population exploded, increasing from less than one billion to more than six billion people in slightly more than two hundred years.
