The website discusses the discovery of 60,000-year-old poison arrowheads in South Africa, suggesting early humans used poison in hunting much earlier than previously thought.
The claims regarding the use of poison arrows 60,000 years ago in South Africa are well-supported by multiple credible sources, including CNN, Live Science, and New Scientist. These sources confirm the discovery of ancient arrowheads with traces of poison, marking the earliest known use of such weapons. The claim about the poison being derived from the gifbol plant is also corroborated by scientific studies. However, the statement about prehistoric hunters' cognitive abilities is an opinion and cannot be factually verified. Overall, the evidence strongly supports the historical claims, leading to a high factual score.
