Traditional education taught that human economic development progressed from hunting to stock farming and then to agriculture. However, the only real difference is that stock farming is an economic method of obtaining food by domesticating livestock, while agriculture involves domesticating plants. Therefore, this three-stage development theory is no longer accepted. Instead, the development of human civilization can be seen in the evolution of transportation. To understand the nature of how the world changes, we should observe the development of transportation. The increasing speed of movement is the main evidence that society is changing rapidly. - Joseph’s “just my thoughts”
Approximately 85% to 90% of the global population is right-handed, while the remainder is left-handed, with very few being ambidextrous. Throughout history, horses have served as a primary mode of transportation for humans. Typically, right-handed individuals mount a horse from the left side, relying on their right hand to grasp the saddle for support. If a person approaches the horse from the edge of a busy road on the left, this naturally orients the horse’s movement toward the left side of the road. Consequently, human anatomical tendencies have influenced the direction of road traffic. This practice led to the establishment of the left-hand shipping rule for vehicles, ships, planes, and even space shuttles. Thus, our civilization on Earth represents a legacy shaped by human anatomical traits. - Joseph’s “just my thoughts”
