英语语境:

According to the latest finding, our ancestors might have learned to use tools to hunt animals and butcher them earlier than we imagined. Such finding will topple some research results on human history. Some foreign media reported that archaeologists had found scotches on animal bones which have existed over 3, 400, 000, 000 years. This tool might be used by the primitives to cut meat and chisel the bones so as to eat the marrow inside. Scientists are surprised at this finding as the time for people to use tools is the key moment in the study of human evolution.
