What did the wheel mean for the peoples of the North Caucasus in the Bronze Age?

The climate of the North Caucasus was especially favorable for cattle breeding and agriculture, plus the mining of bronze and copper ore began. Archaeologists have found four-wheeled chariots with wheels in the form of a solid wooden disc. During the Bronze Age, the first four-wheeled chariots appeared, which significantly accelerated and facilitated the process of transporting mined ore, harvesting, and cultivating land. Chariots were also used in luxurious, for that time, burial rites to deliver the deceased and his belongings to the burial chambers.
