Because of course a community of people living on one food is so realistic. Even the Eskimos and Inuit, living in some of the harshest environments on earth, managed to have a relatively wide variety of foods in their diet. https://en.wikipedia.org/wiki/Inuit_cuisine But okay, let's run with this scenario... > One day, a man invents an automated way to sort good berries from > poisonous berries. Right, because it is totally realistic that a pre-agricultural society living on nothing but berries has mastered the technology to automate sorting berries. > Soon, all the villagers take their berries to him to be > sorted. Of course they do, because why pick only edible berries when it is so much more fun to pick both edible and poisonous berries, mix them together, and then play a game of "let's see if we missed any of the deadly berries and will die horribly after eating them accidentally". In this scenario of yours, is everyone in this a village a workaholic with a death-wish? Why exactly are they doing twice as much work as necessary picking poisonous berries and mixing them in together with the edible berries? > The man dies, but passes the secret on to his son before doing > so.

Even this city boy knows enough to tell the difference between edible blackberries, raspberries and strawberries and the many maybe-its-edible- maybe-its-not berries which grown on random trees and bushes. Are there a bunch of dead birds around the tree? Then its poisonous. Do birds happily eat the berries and keep coming back? Then its worth trying one or two and see if they give you a stomach ache, if not, they're probably safe. A more sensible example would have been mushrooms. And its true, I'm entirely clueless how to identify poisonous mushrooms from edible ones. However will I survive? Nor do I know how to smelt copper, or tan leather using nothing but dung, or perform brain surgery.
