How did one Travel earlier?
In the Stone Ages, the man shifted from one place to another only when the food at the first location became scarce. Families carried their possessions with them with the help of dogs or other animals. In regions with abundant water, simple boats were made for transportation. After the invention of the wheel, new possibilities of transportation came up. The invention of carriages, wagons, and later cars made traveling easier and faster. The only requirement was a network of roads.
