"before agriculture, mankind's main food source were animals (although they still gathered some fruits and vegetables)"
- this is actually not true, since there was a misinterpretation of the remainders of dead animals in human camps, because the great amount plant-based food did not preserve and fossilize like bones. however, with new methodology to examine fossilized plant remainders, scientists found that the ancestral diet contained an overwhelming amount of plant-based and not animal-based food.
