“Coffee and humanity both sprang from the same area in eastern Africa. What if some of those early ape-men nibbled on the bright red berries?
What if the resulting mental stimulation opened them up to a new way of looking at old problems, much as it did Europeans?
Could this group of berry nibblers be the Missing Link, and that memory of the bright but bitter-tasting fruit be the archetype for the story of the Garden of Eden?”
