Final answer:
Neandertals used Mousterian tools, while Modern Humans developed the Folsom point and Upper Paleolithic tools. Both groups used their teeth as practical tools, as evidenced by dental wear patterns.
Step-by-step explanation:
Neandertals are associated with the Mousterian tools, which were smaller hand-axes and tools made from stone flakes. These tools demonstrate the Neandertal's skill in generating small knives for cutting meat, scraping leather, and creating spearheads. Modern Humans, however, developed the Folsom point, a sophisticated technology for hunting large game such as mastodons, and they also created the Upper Paleolithic tools, including a variety of fine stone blades and burins.
Both Neandertals and Modern Humans used their teeth as tools for various purposes, which can be observed from wear patterns on dental remains. This usage was common before the sophisticated tool-making techniques that came to define their respective eras in technological advancements.
