Final answer:
Between 4000 and 3000 BCE, humans made significant technological advances, most notably the invention of the wheel and simple water irrigation systems. These advances greatly improved transportation, productivity, warfare, and agriculture.
Step-by-step explanation:
One of the most important technological advances humans developed between 4000 and 3000 BCE was the invention of the wheel. This invention significantly impacted human society as it made transportation of goods much easier, faster and more efficient. Prior to this, humans had to carry items manually or use animals. The wheel enabled the birth of innovative concepts such as the chariot and the potter's wheel, which advanced industries and warfare. Also, many societies began to develop simple water irrigation systems during this period. This allowed societies to practice agriculture more effectively and establish permanent settlements, instead of leading a nomadic life. Hence, the development of the wheel and water irrigation systems were crucial leaps in human technology within this time frame.
