Early Transportation
- Early humans walked long distances and carried heavy loads.
- They discovered that some animals could be tamed and used for carrying loads and ploughing land.
- Animals made it easier for humans to transport goods.
Development of Rafts
- Early humans learned to tie logs together to make rafts that allowed them to travel and carry heavy loads by river.
Early Land Transportation
- Early humans created sledges or carts that could be pulled along the ground to transport goods.
- They used animals to pull the sledges, but this was not easy due to the limitations of the terrain.
- The sledges could only move where the ground was smooth.
