Final answer:
The historical classifications for artifacts in North America have evolved over time based on geographic designations and the influence of European invasion and colonization. The availability of materials and the type of indigenous animals in each area influenced the style of pottery and clothing ornamentation.
Step-by-step explanation:
The historical classifications for artifacts in North America have evolved over time. Prior to 1600, the cultures were generally grouped into geographic designations such as Arctic and sub-Arctic, Northeast Woodlands, Southeast, Plains, Southwest, Great Basin, California, Plateau, and the Northwest Coast. These groupings were based on the availability of materials and the type of indigenous animals in each area, which influenced the style of pottery and clothing ornamentation. After the 1600s, European invasion and colonization also had an impact on the artwork in every region. It is important to avoid using terms like Prehistory, which suggest that Native peoples didn't have a history prior to European contact.
