D. It allowed them to develop future hunting plans
Explanation:
The Stone Age or also the Lithic Stage is the period of prehistory that ranges from when human beings began to make stone tools until the discovery and use of metals. Wood, bones and other materials were also used (horns, baskets, ropes, leather, or others) but the stone (and, in particular, various conchoidal break rocks, such as flint, quartz, quartzite, obsidian ) was used to make tools and weapons, cutting or percussion. However, this is a necessary circumstance, but not enough for the definition of this period, since in it took place fundamental phenomena for what would be our future: human evolution, the great technological acquisitions (fire, tools, clothing), the social evolution, the climatic changes, the diaspora of the human being all over the habitable world (ecumene), from its African cradle, and the economic revolution from a hunter-gatherer system, to a partially producer system (among other things).
