Is Plant Intelligence Real

The goal of this blog is to create a list of what I call super facts. Super facts are important and true facts that nevertheless are very surprising to many, misunderstood, or disputed among the public. They are special facts that we all can learn something important from. However, I also make posts that are not super facts but feature other interesting information, such as this book review and book recommendation.

“A masterpiece of science writing.” ―Robin Wall Kimmerer, author of Braiding Sweetgrass

“Mesmerizing, world-expanding, and achingly beautiful.” ―Ed Yong, author of An Immense World

“Rich, vital, and full of surprises. Read it!” ―Elizabeth Kolbert, author of Under a White Sky and The Sixth Extinction

Award-winning Atlantic staff writer Zoë Schlanger delivers a groundbreaking work of natural history and popular science that probes the hidden world of the plant kingdom, “destabilizing not just how we see the green things of the world but also our place in the hierarchy of beings, and maybe the notion of that hierarchy itself.” (The New Yorker)

It takes tremendous biological creativity to be a plant. To survive and thrive while rooted in a single spot, plants have adapted ingenious methods of survival. In recent years, scientists have learned about their ability to communicate, recognize their kin and behave socially, hear sounds, morph their bodies to blend into their surroundings, store useful memories that inform their life cycle, and trick animals into behaving to their benefit―a fascinating display of plant behavior and sensory abilities, to name just a few remarkable talents.

The Light Eaters is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In this captivating exploration of plant intelligence, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system. What is intelligent life if not a vine that grows leaves to blend into the shrub on which it climbs, a flower that shapes its bloom to fit exactly the beak of its pollinator, a pea seedling that can hear water flowing and make its way toward it? Zoë Schlanger takes us across the globe, digging into her own memories and into the soil with the scientists who have spent their waking days studying these amazing entities up close.

What can we learn about life on Earth from the living things that thrive, adapt, consume, and accommodate simultaneously? More important, what do we owe these life forms once we come to understand their rich and varied abilities? Examining the latest epiphanies in botanical research, Schlanger spotlights the intellectual struggles among the researchers conceiving a wholly new view of their subject, offering a glimpse of a field in turmoil as plant scientists debate the tenets of ongoing discoveries and how insights into plant communication influence our understanding of what a plant is.

We need plants to survive. But what do they need us for―if at all? An eye-opening and informative look at the ecosystem we live in, this book challenges us to rethink the role of plants―and our own place―in the natural world, tackling the enthralling question of plant consciousness along the way.

This is my five-star review for The Light Eaters

It is a truly great and fact filled book

Plant Behavior and Communication is Real. What about Plant Intelligence?

This is a very interesting book that describes the ways plants behave and communicate via chemicals, fungus, sound, electric signals and light. Many plants even exhibit memory functions and are able mimic the look of other plants from a distance. A leaf is the only thing in our known world that can manufacture sugar out of materials, light and air, that have never been alive. They can produce complex chemicals, like caffeine, that humans and animals can’t produce. If weighed, plants would amount to 80% of Earth’s living matter. Plants can regrow virtually any amputated part. Some plants inject poisons into the ground around their roots to prevent anything else from growing nearby. Plants can recognize and protect their kin. Many plants will rearrange their leaves to avoid shading siblings. One of the points of the book is that we may have underestimated plants.

The book also discusses the possibility that plants may have a type of intelligence, perhaps even consciousness, depending on how you define it. This is a philosophical discussion. It should be noted that there was a very popular book in the 1970’s that made outlandish and pseudoscientific claims about plants. In the long run this book created a lot of skepticism towards claims within botany that seemed far-fetched despite collaborating evidence. The author laments this conservatism at the same time as she understands it. There is a problem with getting unconventional work published in botany, at the same time the arduous peer-review process is an essential safeguard against false paths.

However, it has been established that plants do a lot of amazing things, and we are just beginning to realize the extent of plant behavior and communication. Some examples are, plants can communicate with each other even when they are too far apart to be passing information through their roots (perhaps pheromonal substances). Plants produce electrical impulses and seem to have nodes at the tips of their roots that serve as local command centers. Plants can react to an attack of munching insects by summoning those insects’ specific predators to come and pick them up. Plants can perceive gravity, but we don’t know how. Primrose increases the sweetness of its nectar within three minutes if you play an audio recording of honeybee flight to it. Pea plants and many other plants grow their roots toward the sound of running water.

Other examples are, Tomatoes make thirty-five sounds per hour when drought stressed. Goldenrod can sense the volatile signals of nearby gall-forming flies and jump-start its immune system before the flies even make contact. Researchers who played tones at different frequencies to alfalfa sprouts for two hours saw that they increased the plants’ content of vitamin C. Plants can hear the caterpillars or pick up the vibrations they cause. Trichomes allow plants to sense the footsteps of moths and caterpillars.

Nasa poissoniana can store and recall information. It can remember the time intervals between bumble bee visits and anticipate the next time their pollinator was likely to arrive. Bittersweet nightshade recruit ants as bodyguards. Cornish mallow, a pink-flowered plant, will turn its leaves hours before sunrise to face the horizon in exactly the direction its expects the sun to rise. A common vine in this rainforest was capable of spontaneously morph into the shape of almost any plant it grew beside. Plant mimicry is not that unusual. Scientists have long observed that virtually all plants are highly sensitive to touch of any kind and will change their growth accordingly. The book features several dozen more amazing examples of plant behavior, communication, sensing, and forms of memory including generational memory.

The book also delves into some other topics such as the importance of microbes for both plants and animals, including humans. Microbes influence our immune systems, our smells, and our attractiveness to mosquitos. Emerging research suggests that they may play a role in autism, depression, anxiety, and possible even who we are attracted to. The author also notes that pollution steadily filling the air appears to sabotage plants ability to send and interpret each other’s signals.

This is a book that is filled with interesting and perhaps even shocking information, and it certainly made me more interested in plants and botany. I think the book made the outlandish ideas about plant intelligence and conscience appear almost plausible. Plants are all around us and they are more interesting than I thought. The book is also well written and well organized. I should say that I did not think the first three chapters were very interesting, but it got better the further I read. I highly recommend this book.
