This Is What Potatoes Look Like

This isn't exactly a fact I never knew, but the specifics of the fact... wow!


These are Peruvian potatoes, demonstrating the genetic diversity of a species in the area where it originated.

Go back to the source for the most genetic diversity -- that was a fact I never knew until I read Michael Pollan's The Botany of Desire. (The wellspring of apples, by the way, is the area where Kazakhstan, Kyrgyzstan and China come together.)
