How psilocybin evolved has more to do with sending insects on terrifying trips than it does making Phish sound good.


  • Fungi species that produce psilocybin—the main hallucinogenic ingredient in "magic" mushrooms—aren't closely related to one another.
  • Researchers have discovered that the way these fungi independently gained the ability to produce psilocybin is because of horizontal gene transfer.
  • Based on how uncommon horizontal gene transfer is in mushroom-producing fungi and the types of fungi that produce psilocybin, it seems likely that the hallucinogenic chemical is meant to scramble the brains of insects competing with fungi for food.

Throughout our history, human beings have demonstrated a powerful and committed love of tinkering with our brain chemistry. We drink the waste of sugar-eating bacteria, smoke the leaves of garden-variety weeds, and munch on mushrooms whose chemicals give us such a strange experience we have to call it magic.
