Jeremy Narby's Intelligence In Nature

627 Words2 Pages

While reading Jeremy Narby’s book, Intelligence in Nature, which was published in 2005, you will find a collection of work and theories from multiple scientists. Some of the scientists featured in the book try to support the idea of plants being intelligent, some argue that animals are intelligent, and some argue that nature is mechanical and has no form of intelligence. The majority of the evidence leads readers to believe that there is intelligence in nature, amongst both plants and animals. Animals, for the most part, have brains so it is easier for society to accept the idea that animals can be intelligent. Plants on the other hand, do not have a brain making it harder for people to grasp the idea that plants can be intelligent. Narby mentions …show more content…

Charles Darwin once compared the root tips of plants to “the brain of one of the lower animals” he even reported electrical signal systems in plants, much like a nervous system. More than a century after Darwin, a scientist named Mancuso discovered the center for the electrical signals, or action potentials, is located in the root tips. Even small plants had nearly 14 million root tips, all acting in a similar way to a nervous system. Humans and most animals have centralized brains, meaning it is all grouped together in one spot, forming what we envision as a brain. Plants may not have a centralized brain like humans, but that doesn’t mean they lack a brain, in fact plants have “decentralized intelligence” distributed throughout them. Since plants cannot react quickly, they have no way of defending themselves against predators, so by scattering the “brain” plants avoid dying off when damaged (Marinelli). The root tips and sensory cells allow plants to feel and react to different stimuli. It is uncertain as to whether plants feel pain, but they do respond to anesthetics and react to being damaged. For example, when a caterpillar eats a plant’s leaf, the plant begins to secrete defensive chemicals. The censor cells react to the damage being done and cause the leaf to secrete chemicals to fend off the predator, as well as repair the
