Scientists found that the magic behind so-called “magic mushrooms”—psilocybin, a psychedelic compound—has evolved at least twice in mushrooms, and in very different ways.
Researchers in Germany and Austria examined two different types of magic mushrooms. They showed that while both kinds make psilocybin, the biochemistry each relied on to produce the natural compound were entirely distinct. The findings suggest psilocybin may be an example of convergent evolution, in which two, unrelated forms of life nevertheless evolve to develop similar traits or features.
“Mushrooms have learned twice independently how to make the iconic magic mushroom natural product psilocybin,” the authors wrote in the paper, published last month in the journal Angewandte Chemie International Edition.
Cattle or other grazing animal would be a prime candidate for loitering and then for some extended loitering. (Sorry for the shorts link, but it's for science and it's a time lapse of cattle in a field: https://youtube.com/shorts/hXPw-mxEBIY)
A side thought is that kind of movement would be perfect for spore distribution in a smaller area with similar growing conditions. It probably would increase the chance that similar strain momma and daddy spores meet. (Large dung piles also happens to be a decent medium for some mushroom strains.)
That still doesn't prove anything scientifically or even build a case, but at least you got a time lapse video of cattle in a field.
