One Wheel Transport Evolution

History
Evidence of wheeled vehicles appears from the mid 4th millennium BCE, near-simultaneously in Mesopotamia, the Northern Caucasus (Maykop culture) and Central Europe, so that the question of which culture originally invented the wheeled vehicle remains unresolved and under debate.
The earliest well-dated depiction of a wheeled vehicle (a wagon—four wheels, two axles), is on the Bronocice pot, a ca. 3500–3350 BCE clay pot excavated in a Funnelbeaker culture settlement in southern Poland.
