Edit: looking at all the elaborate replies, I cannot help being amazed. Here I thought the Fedi is overrepresented by computer geeks (such as yours truly) but obviously they’ve got NOTHING on the biologically inclined here! 🥰😍
If poisonous mushrooms are poisonous because it is advantageous for the survival of the specific species, are non poisonous mushroom relatively speaking weaker, less well equipped for the furthering of their species? I suppose that the ability to survive and further a species is multifaceted and that being poisonous or the lack thereof is just one of many parameters?


THC is also a detterant
it’s usually not good for your survival if you’re stoned (if you’re a wild animal)
And now it’s suddenly a reproductive strategy. The same with what chili intended as poison. Hemp and chili wouldn’t grow a tenth as much as they do if it wasn’t fornus liking their poison.
