Prehistoric wheeled transportation

Some of the world's first farmers may have sped around in two-wheeled carts pulled by camels and bulls, suggests a new analysis on tiny models of these carts that date to 6,000-5,000 years ago.

The cart models, which may have been ritual objects or children's toys, were found at Altyndepe, a Chalcolithic and Bronze Age settlement in Western Central Asia near Ashgabat, Turkmenistan. Together with other finds, the cart models provide a history of how wheeled transportation first emerged in the area and later developed.
