Step-by-step explanation:
The discovery and use of fire by early humans provided several advantages. One main advantage was that fire was used for cooking, which improved nutrient availability. Cooking meat made it easier to consume and digest. Fire also provided protection against predators and competitors.
Additionally, fire was used as a tool for hunting, as it could be used to harden wooden spears or treat certain types of stone to make them more effective.
Furthermore, the use of fire had cultural and social implications, as gathering around the heat and light of a fire helped build social connections and aided in cooperative activities and group survival.
