it also infers(from the Chimps studied) that man could do well on a mostly veggie (dare I say Fruitarian) diet (of course detractors would say, 'just for a year').
But, it gets back more to what I always say that at least for me, to be happily vegan, I included more wild foods - our domesticated food crops just wasn't enough, be it nutritionally or whatever.
I am definitely intrigued about the Chimps use of piths - as nowadays Science is getting around to 'glyconutrients', and the chimps do this 'instinctively'.
