One Wheel Transport Evolution

The Latin word rota is from the Proto-Indo-European rotā-, the extended o-grade form of the root ret- meaning "to roll, revolve".
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.
