The design principles for solving the tragedy of the commons can be applied to all groups.

“As an evolutionary biologist who received my PhD in 1975, I grew up with Garrett Hardin’s essay “The Tragedy of the Commons,” published in Science magazine in 1968. His parable of villagers adding too many cows to their common pasture captured the essence of the problem that my thesis research was designed to solve. The farmer who added an extra cow gained an advantage over other farmers in his village but it also led to an overgrazed pasture. The biological world is full of similar examples in which individuals who behave for the good of their groups lose out in the struggle for existence with more self-serving individuals, resulting in overexploited resources and other tragedies of non-cooperation.

Is the so-called tragedy of the commons ever averted in the biological world and might this possibility provide solutions for our own species? One plausible scenario is natural selection at the level of groups. A selfish farmer might have an advantage over other farmers in his village, but a village that somehow solved the tragedy of the commons would have a decisive advantage over other villages. Most species are subdivided into local populations at various scales, just as humans are subdivided into villages, cities and nations. If natural selection between groups (favoring cooperation) can successfully oppose natural selection within groups (favoring non-cooperation), then the tragedy of the commons can be averted for humans and non-human species alike…”
