Humans Ate Fish 40,000 Years Ago
At least one of our ancestors regularly ate fish 40,000 years ago, a new study finds.
Scientists analyzed chemical compositions of the protein collagen in an ancient human skeleton from Tianyuan Cave near Beijing to reach their conclusion.
Fishing at this time must have involved considerable effort, the researchers think, because fossil records suggest humans were not using sophisticated tools — beyond crude stone blades — until about 50,000 years ago.
