At the bouri site in ethiopia, what did paleoanthropologists find accompanying the fossils attributed to australopithecus garhi? \

They found animal bones that had cut marks on them

This was of extreme importance because it meant that these hominids who lived very early in the human evolution cycles had ways of using tools made out of stones to hunt or in any way affect the animals around them. This showed how some early people managed to devise those tools and use them practically. 

Why do you have to ask such hard questions.
