Nature Is Always Listening

From The Marginalian:

Fungi are the evolutionary cardinals of the Earth — the first to conquer it and the last to inherit it, composing the living substratum beneath every forest and every field and every backyard ecosystem. Each cubic inch of mycelium compresses eight miles of fine filaments folded unto themselves — the original superstrings of this terrestrial universe. Wildly unlike us, they are inseparable from our creaturely inheritance. Since the dawn of our adolescent species, they have been touching our cuisine and our consciousness in ever-evolving ways, the underlying mystery of which we are only just beginning to unravel. 

In the early 2000s, a series of groundbreaking studies began revealing yet another facet of that mystery — the way mushrooms respond to sound, despite having no auditory organs. One [PDF] found that high-frequency sounds inhibit spore generation and mycelial growth. Another [PDF] affirmed the correlation from the other side, finding that low-frequency sound waves stimulate mycelial growth. The aptitudes and abilities of every organism — ours included — are puppeteered by evolutionary adaptation. This means the curious relationship between sound vibration and mycelial growth must confer some substantive evolutionary advantage upon mushrooms, honed over the eons. Master-mycologist Paul Stamets, author of the millennial bible Mycelium Running: How Mushrooms Can Help Save the World (public library), set out to solve the enigma. (Read more.)
