Butchered animal residues discovered on 250,000-year-old tools

Protein residue from butchered animals has been found on 250,000-year-old tools found in Jordan. While stone tools have been found before, the residue of the kinds of animals found on these ancient tools brought back surprising results, linking rhinoceros, horse, wild cattle and duck to these hominins.

Fishing at this time must have involved considerable effort, the researchers think, because fossil records suggest humans were not using sophisticated tools —

Oldest Dinosaur Protein Found – Blood Vessels, More

The hints of hemoglobin remain speculative and are not covered in the new, peer-reviewed study, which appears in today's issue
