Final answer:
The Edwards Plateau lithic outcrops provided Native Americans with materials for making various tools and resources for art and everyday life, including harpoons, woodworking tools, and materials for trading, which contributed to social transformations.
Step-by-step explanation:
The Edwards Plateau lithic outcrops provided Native Americans with a variety of resources ideal for making tools. The information provided mentions that Native Americans designed harpoons out of bone for hunting marine mammals and polished rocks into woodworking tools for creating items such as dugout canoes. They also developed sophisticated woodcarving techniques for art, crafted special fishhooks, and used tree bark to create cloth and baskets. Stones, copper materials, and shells were traded, leading to social transformations over time. Similarly, indigenous peoples of the plains used animal materials for decoration, such as bison bones to hold paint, dyed porcupine quills, and leather for clothing. As European settlements expanded, Native Americans began incorporating European goods into their daily lives, such as textiles, metal cookware, and flint and steel for fire starting.
