Plants are very intelligent and far more capable than what we give them credit for. Research from 2010 published in Plant Signaling & Behavior hypothesizes that since they cannot escape environmental stresses in the manner of animals, they have developed a “sophisticated, highly responsive and dynamic physiology,” which includes information processes such as “biological quantum computing” and “cellular light memory” which could be described as forms of plant intelligence. Titled, “Secret life of plants: from memory to intelligence,” the study highlights one particular factor of plants showing their success as intelligent beings:
“There are living trees that germinated long before Jesus Christ was born. What sort of life wisdom evolved in plants to make it possible to survive and propagate for so long a time in the same place they germinated?”
According to the researchers, “plants actually work as a biological quantum computing device that is capable to process quantum information encrypted in light intensity and in its energy.” This information processing includes a mechanism for processing memorized information. For example:
“plants can store and use information from the spectral composition of light for several days or more to anticipate changes that might appear in the near future in the environment, for example, for anticipation of pathogen attack.”
According to the study, “plants can actually think and remember.”
rover Cleveland Backster Jr., was an interrogation specialist for the Central Intelligence Agency (CIA), who became well known for his experiments with plants using a lie-detector machine. Through his research, he believed that plants feel pain and have extrasensory perception (ESP). Author Michael Polan describes his experiments quite well in a piece he wrote for the New Yorker a few years ago regarding plant intelligence:
(Cleve) hooked up a galvanometer to the leaf of a dracaena, a houseplant that he kept in his office. To his astonishment, Backster found that simply by imagining the dracaena being set on fire he could make it rouse the needle of the polygraph machine, registering a surge of electrical activity suggesting that the plant felt stress. “Could the plant have been reading his mind?” the authors ask. “Backster felt like running into the street and shouting to the world, ‘Plants can think!’ ”
Backster and his collaborators went on to hook up polygraph machines to dozens of plants, including lettuces, onions, oranges, and bananas. He claimed that plants reacted to the thoughts (good or ill) of humans in close proximity and, in the case of humans familiar to them, over a great distance. In one experiment designed to test plant memory, Backster found that a plant that had witnessed the murder (by stomping) of another plant could pick out the killer from a lineup of six suspects, registering a surge of electrical activity when the murderer was brought before it. Backster’s plants also displayed a strong aversion to interspecies violence. Some had a stressful response when an egg was cracked in their presence, or when live shrimp were dropped into boiling water
His (Backster’s) work on this was published in the International Journal of Parapsychology.
Monica Gagliano, a thirty-seven-year-old animal ecologist at the University of Western Australia has conducted multiple experiments with plants that suggest they are a living, thinking, feeling and emotional beings.
