iam having trouble with the fact of WHY trees being conscious would be
necessary(or if its necessary), evolutionary wise.
one of the big problems of consciousness is whether consciousness is evolutionarily necessary at all, even in humans. A great entry point into this problem which is related to to this question is that of philosphical zombies.
is it possible that trees can communicate on some sort of level that
we may not understand yet?many other creatures have strange ways of
communicating.is it possible/probable that trees can also have some
form of communications that we have yet not understood or realized?
as noted by Thomas Klimpel plants indeed have evolved a complex biochemical system for information exchange through pheremonal sygnals such as ethylene, which signals ripening, released in high quantities by ripe bananas, and which can be used as a really effective way of coaxing other nearby fruit to ripen ..
There is also a long history both within and outside of indigenous cultures of people who subscribe to the notion of 'plant teachers', the idea that ingestion of psychoactive plants imparts knowledge of a spiritual kind through the alterations they produce in perception. The most common of these fall into the category of hallucinogens, and are referred to by many their modern day devotees as entheogens. A few of the innumerable people who write on this area are Terrence Mckenna, Dr Rick Strassman MD, Carlos Castenada, and Aldous Huxley. Seeing as your question relates to how it can be proved, not can it be proved, would entheogenisis constitute a legitimate method for investigating this question ?
