Final answer:
Fire improved the life of early hominins by providing warmth and protection, enabling cooking, aiding tool manufacturing, and serving a social function.
Step-by-step explanation:
Fire improved the life of early hominins in several ways:
- Warmth and Protection: Controlled fires provided warmth, which was crucial for early hominins living in cold climates. Fire also helped scare off predators, providing a sense of security.
- Cooking: Fire was used to cook meat, making it easier to consume and digest. The ability to cook allowed early hominins to access more nutrients and expand their diet.
- Tool Manufacturing: Controlled fires were utilized to harden wooden spears and treat certain types of stone. This made tools more effective for hunting and shaping, contributing to the advancement of early hominin technology.
- Social Function: Gathering around fires for heat and light fostered social connections and bonding, which were vital for cooperation and group survival.
