Final answer:
The faunal evidence associated with Oldowan tools suggests their use in processing meat, evidenced by cutmarks on animal bones, and indicates social cooperation in early hominins who may have transported their prey for shared consumption.
Step-by-step explanation:
Based on the faunal evidence found in association with Oldowan tools, it appears that the creators of these tools processed and consumed meat. Cutmarks on animal bones suggest that the Oldowan tools, which were simple and crudely made by chipping flakes from a stone core using hard hammer percussion, were used for butchering and possibly processing plants. The significant number of large animal carcasses found at sites such as Gran Dolina, with predominately Oldowan style tools, indicates that early hominins might have transported their prey to a common site for consumption. This behavior has been interpreted as evidence of social cooperation, possible division of labor, and food sharing among groups. The Oldowan tool industry, which dates back to around 2.6 million years ago, is credited mostly to Homo habilis and represents a substantial leap in human technological ability.
