The trees were acacias (there may be other species that do this, I don't know) and the pheromone was ethylene, which is a very simple gas that's used in development of other things in plants, famously like fruit ripening but likely more (can't remember, prob bud development). <https://asknature.org/strategy/leaves-signal-presence-of-predators/> https://asknature.org/strategy/leaves-signal-presence-of-pre... > If a single tree under duress is using its resources and energy to signal to other trees that have no way of directly helping the tree in question, what evolutionary advantage is being provided to the tree releasing the pheromones? Its genetic legacy is being enhanced, if the trees it's protecting are related, which likely they are (very elegant phrasing though! upvoted just for that) > thus reproduce more successfully", and that awareness may be a form of consciousness different than our own Hmm. Be careful here. I need to sit down and read and understand this so please recognise I'm dumping this on you, but "Michie’s design, called MENACE, was a large pile of matchboxes that contained a number of beads and learned to play tic-tac-toe." ... "MENACE could never win against the perfect algorithm, but ended up drawing every time after about 90 games, making it equally as perfect" <https://opendatascience.com/menace-donald-michie-tic-tac-toe-machine-learning/> https://opendatascience.com/menace-donald-michie-tic-tac-toe... I dunno. Where do you draw the line? HTH anyway.
