If you’re curious enough to go down the rabbit hole, watch this excellent talk by famed mycologist Paul Stamets exploring evolutionary biology, human evolution and the enduring mystery of consciousness.
“I see the mycelium as the Earth’s natural Internet, a consciousness with which we might be able to communicate. Through cross-species interfacing, we may one day exchange information with these sentient cellular networks.
Because these externalized neurological nets sense any impression upon them, from footsteps to falling tree branches, they could relay enormous amounts of data regarding the movements of all organisms through the landscape.
I believe that mycelium is the neurological network of nature. Interlacing mosaics of mycelium infuse habitats with information-sharing membranes. These membranes are aware, react to change, and collectively have the long-term health of the host environment in mind.
