Answer:
Ever since the first hunters exchanged animal skins, people have been involved with trade. Whether buying, selling, or bartering, people groups found a way to exchange the goods and services they had for those they wanted from another group.
The first kind of trade that took place between people was bartering. For example, a hunter might barter a bear skin for a flint ax. If each person needed what the other person had, they would trade straight across. There is evidence of trade by bartering as early as 4000 B.C.
As hunter-gatherers settled down and formed communities, other items, such as farming equipment, became valuable. People began to learn the value of ores such as gold, silver, and copper for making jewelry. As communities grew, they learned of faraway places. They took items to trade and returned with things that people were willing to barter for.
