In 1958, Demitri Belyaev and Lyudmila Trut started an experiment on domestication. From a large group of foxes, they selected the ones that reacted to humans with more curiosity and less aggression. In each generation, they selected only the friendliest pups to become parents — hoping to recreate the process that originally led to domestication thousands of years ago.

In The Fox Experiment, you’ll breed your own domesticated foxes. In each round you’ll select a pair of fox parents, then you’ll assign their pups traits through a unique drafting mechanism that simulates the uncertainty of genetics.
