Answer:
Chimpanzees and early humans both used tools to make their everyday lives easier. Chimpanzees use tools to crack open nuts and even make wooden spears to hunt smaller primates called bush babies. Early humans fashioned stone hammers and other crude tools to assist in skinning and cutting food. However, chimpanzees don’t use tools to make other tools, as early humans did when they created the first stone knives. The creation and usage of tools requires advanced problem-solving skills and a high level of cognitive abilities, intellectual feats that, for a long time, seemed only accessible to humans.
