Archaeologists and historians attribute the invention of the wheel to the ancient Sumerians of Mesopotamia around 3,500 B.C. It's most probable that the wheel came about as a series of slow incremental advances to existing technologies, rather than one giant leap.
The first wheels in ancient Sumer were used as potters' wheels to form ceramics, such as pots and jugs, before use in transportation. The wheel and most forms of circular motion aren't visible or present in nature. Wheels as transportation tools likely arose from the practice of rolling heavy objects long distances on logs and sledges. The wheel gave its inventors definitive advantages in trade, pottery production, transportation and warfare.
