We humans are not the only species that design packages. Many of the plants we eat spent ages designing their own packaging for the fruit, roots, seeds and other parts of themselves that critters like us use for nourishment.

Take for instance the humble spud we know as the potato. Most of the plant, including the stalk, leaves and flowers are toxic to humans, however, the tuber which nourishes the plant is full of tasty starch. Covering that source of nutrition for the plant is a tough outer skin, which is occasionally eaten, but often it’s peeled off when preparing French fries.
