Evidence against traditional view ·Grooves on animal bone fossils
Markings made by stone tools on animal bone fossils are different from those made by carnivores' teeth or sedimentary abrasion. Animal bone fossils had carnivore markings underneath markings made by tools, and the tool markings were not systematically at joints. (The implication is that if our ancestors were hunters, we'd expect to see tool markings at joints and we wouldn't see carnivore marking underneath the tool markings.)

Not supported. Although we know that taphonomy has been applied to fossils and tools that were almost 2 million years old, that doesn’t imply taphonomy helped discover the age of the fossils.
