Primitive structures refer to the basic forms of construction used by early human societies. These structures often include simple shelters made from natural materials like wood, stone, and animal hides. They were designed to provide protection from the elements and predators, reflecting the needs and resources of the communities that built them. Examples of primitive structures include wigwams, teepees, and thatched huts. These designs were typically temporary or semi-permanent, allowing for mobility as resources changed. Over time, these structures evolved into more complex forms, laying the groundwork for modern architecture and construction techniques.
