Based on the "Tool Use" section, which of the following statements about the earliest evidence of tool use by hominins is true?

  • A: It involves modified sticks and leaves used as "shoes."
  • B: It dates back to 3.5 million years ago and was found in East Africa.
  • C: It consists of cut marks on animal bones from Ethiopia, suggesting tool use before large brain evolution.
  • D: It was primarily associated with Homo habilis, who lived 2.4 to 1.6 million years ago.

Explanation

The 'Tool Use' section states, 'The oldest generally accepted evidence of tool use by hominins is 2.5-million-year-old cut marks on animal bones found in Ethiopia... If these hominins, which have been named Australopithecus garhi, were in fact the creators of the stone tools... that would suggest that stone tool use originated before the evolution of large brains in hominins.'
