The appearance of the car

When we walk on the streets and face the endless flow of colorful cars, when we travel and sit on fast trains and airplanes, do you know how our ancestors first invented transportation?

In ancient times, most people lived along rivers. With the application of fire and stone axes, the earliest water vehicle - the canoe - was created to meet the needs of fishing and crossing rivers.

More than 5,000 years ago, humans domesticated cattle, horses, donkeys, camels, elephants, yaks and other animals and used them for transportation to reduce their labor burden. At this time, livestock that could help people carry items became an important means of transportation on land.

With the need to transport items and hunt long distances, people invented the sled. The sled has a relatively complex structure and can be walked on snow, land or grass. It is said that the car developed step by step from the sled. People discovered that rolling was faster through sleds, so log rollers gradually evolved into axles and wheels. In this way, the wheel was invented.

The rickshaw is the earliest transportation vehicle that appeared. The original vehicles relied on people to push or pull. After the emergence of cars, in order to speed up transportation and increase transportation volume, there was a requirement to build roads.

This is how our ancestors continued to develop and improve transportation.
