Step-by-step explanation:
Cooking, light, and warmth were advantages to indigenous people at Border Cave. Controlled fires provided warmth in cold climates, scared off predators, and enabled cooking. The use of fire also played a role in tool manufacturing and social bonding.
Archaeological finds suggest that controlled fires aided in the hardening of wooden spears and the treatment of stones to facilitate shaping. Gathering around the heat and light of the fire likely helped build social connections and enabled cooperative activities and group survival.
