TWO WORDS.

Transportation has changed in many ways over the years. The oldest known form of transportation is the boat. Around 60,000 years ago, boats were made by hollowing out a tree trunk, also known as a canoe. Riders had to use paddles to control the canoe across the water. However, today boats are more convenient because they have an engine that powers them.

Next came horses. Surprisingly it took 55,000 years after the invention of the boat to discover horses as a means of transportation. At first, horses were ridden without a saddle, also called riding bareback. But over time, riders used saddles to make traveling more comfortable and easier to control the horse. After that, it didn’t take long for us to figure out we could use a wagon and a horse to help carry equipment and people.
