Explanation:
The Chalcolithic Period
At one point, all human societies relied on stone tool technology. Eventually, some of these cultures started the process of developing agriculture, still with stone tools, which we call the Neolithic period, or New Stone Age. Then, many societies discovered bronze, which kicked off what historians call the Bronze Age. The transition from the Neolithic to the Bronze Age took experimentation, failure, and innovation, creating a society that actually relied on bronze tools.
The period between the late Neolithic and the early Bronze Age, during which human societies started experimenting with metal tools and slowly reorganizing their societies, is called the Chalcolithic period. Like the Stone Ages and the Bronze Age, it's also named after the material that changed everything. Welcome to the Copper Age.
Starting the Copper Age
The Copper Age was a time of profound social and cultural change. It should be noted that not all societies started this process at the same time, or in the same way. Some never adopted metal at all. However, many of these changes first occurred around the eastern Mediterranean. The story begins around the end of the 5th millennium BCE. The climate, which had been great for agriculture, became drier, and many societies returned to hunter-gatherer lifestyles. With the domestication of animals that had occurred, many also resorted to pastoral ranching rather than crop farming. All of this brought people into fiercer competition for resources and encouraged experimentation with new materials for more efficient tools.
Two metals suddenly became attractive candidates. One was gold. Gold is pretty and easy to work with, but is extremely soft and isn't great for tools; so, people used it for jewelry. However, gold is often found alongside another mineral: copper. Copper is relatively easy to heat and work into various shapes, but is much stronger than gold once cooled. Ancient craftspeople had their new material.
Social Changes in the Copper Age
The true Copper Age is considered to have lasted from around 3500 to 2300 BCE. During this time, human societies began widely utilizing copper for a variety of reasons. They used it to make metal tools for agriculture, construction, and other aspects of daily life. They were still using stone tools as well, but metal was becoming pretty appealing. They also used copper for weapons, to defend their resources in this era of competition. Warriors quickly rose to the top of society as elite and respected protectors of the village.
