In the early 1990s, psychedelic advocate and ethnobotanist Terence McKenna published his book Food of the Gods in which he surmised that homo sapiens' cognitive leap forward was due to their discovery of magic mushrooms. The scientific community never took McKenna's theory very seriously, considering it mostly trippy speculation — these days, his ideas have largely been relegated to the spacier corners of Reddit. Now, however, the idea has acquired a new advocate, psilocybin mycologist Paul Stamets, who's suggesting McKenna was right all along.
