Is it true that chimpanzees are strictly herbivorous animals?

No. Chimpanzees are not strictly herbivorous; numerous field studies demonstrate that they regularly hunt, consume vertebrate meat, and ingest animal protein as part of their natural diet.

Verdict: REFUTED · 0 sources for, 6 against · Last checked

The analysis

The claim states that chimpanzees are strictly herbivorous, but multiple peer-reviewed studies (e.g., [1], [2], [3]) document active hunting and regular consumption of vertebrate meat by chimpanzees. Therefore, the claim is clearly refuted by empirical evidence.
