the hippies who made JCS would be proud
Last year, for a long term project, I studied speech patterns and compiled a report on the history and science of speech. One section required that I research theories as to the origins of speech. My favorite?
The Psychedelic Glossolalia Hypothesis"As the continent of Africa began to dry, grassland savannas opened, forcing humans out of the forests and into the plains where the dung of large herbivores was ubiquitous. Species of tryptamine-bearing fungi (symptom -- glossolalia, or nonsensical speech) which live on animal dung would have been very attractive to human populations seeking a new food source. Regular ingestion of the fungi could, over a long period of time, have stimulated complex vocalizations that eventually led to communicative speech."
In other words: Early humans, tripped out on drugs, developed speech through hallucinations.
I wonder if someone used that same method to come up with this sign. In any case, it's a shame we don't see this more often.
