The Earliest Humans Primarily Used Tools to ____

Question

The earliest humans primarily used tools to ____.  
A) assist in locomotion
B) provide protection
C) facilitate the processing of food
D) ward off predators
E) construct shelters

Accepted Answer

The earliest humans primarily used tools to facilitate the processing of food, such as grinding, cutting, and scraping. This allowed for easier consumption and digestion of plants and meat. While tools may have also been used for other purposes such as providing protection, warding off predators, and constructing shelters, the primary use was for food processing. Locomotion would have been aided by bipedalism, a natural adaptation, rather than tools.
