Non sequitur response. We were debating need to eat animal protein for brain function. Elephants have good functioning brains without any animal protein.
You brought up animal protein, the article just references protein. There is plenty of protein in the grasses and leaves and bushes elephants eat. There is minimal protein in fruit but elephants eat that too.
Research has shown that all plants contain protein and at least 14% of the total calories of every plant are protein.
