Summary:

- Archaeologists have discovered evidence of ancient vehicles, potentially dating back 20,000 years, in New Mexico. This is one of the oldest known examples of wheeled vehicles discovered in the Americas.

- The artifacts include stone and bone fragments that appear to be the remains of a primitive sled or travois, a type of transport device used by ancient peoples to haul goods. This suggests these early inhabitants had developed basic transportation technology.

- The discovery challenges the commonly held belief that the first wheeled vehicles in the Americas emerged much later, around 3,500 years ago. This finding pushes back the timeline for the development of ancient transportation in the region.
