Discovering Intelligence in Unexpected Places
If our human intelligence has discerned over thousands of years which plants are edible and nutritious and healing, wouldn’t the evolutional ingenuity of plants which feed and sustain us and all life also constitute intelligence?
From the largest to the smallest and the oldest to the youngest creatures on Earth—Antarctic blue whales and coastal redwood trees, minute bacteria and human beings—we are all enmeshed in layers of relationships. We need each other, though some more than others.
Plants evolved hundreds of millions of years before the first humans and transformed the Earth—through their creativity in surviving predators—into a livable environment for all animals, including humans. We needed plants for our evolution and need them now for our survival from climate disaster. They, however, did not need us for their existence and would survive without us.
Putting humans at the top of the evolution chain as the crown of intelligent life, a Western worldview, is—as some keenly grasp—mistaken. The baleful consequences of this simplistic hierarchy are everywhere: out-of-control climate change; accelerating rates of animal and plant extinction; dead zones in the oceans and mass mortality of coral reefs; the vast pollution of land, air, and water; and the mounting likelihood of human extinction with nuclear war. All caused by humans, humans with financial and political power much more egregiously than others.
Perhaps you have you noticed that late summer asters and goldenrod tend to grow as companions. Why? Together—their combined beauty—attracts more pollinators.
Certain scientists who study plants—from the simplest to the exotic—are stirring controversy with their “ Are plants intelligent?” Consider that we humans owe our lives to plants for their food, medicines, and critical balance of 21% oxygen in the air we breathe. If our human intelligence has discerned over thousands of years which plants are edible and nutritious and healing, wouldn’t the evolutional ingenuity of plants which feed and sustain us and all life also constitute intelligence?
Studies have found that elephants recognize themselves in a mirror, crows create tools, dolphins demonstrate empathy and playfulness, and cats exhibit similar styles of attachment as human toddlers. The given explanation is that they have brains with neurological capacity for consciousness and intelligence.
But plants do not have a central brain. Could their mode of learning to evade insect predators and maximize their growth come from a diverse form of intelligence, possibly be distributed across their roots, stems, and leaves? Could the whole plant, then, function as a brain? Recent studies of plants have stirred the possibility that they are conscious and intelligent. Take communication, something we humans claim as our domain through language and more recently acknowledge that animals also possess.
Botanists have found that not only do alder and willow trees alter their leaf chemistry to defend themselves against an invasion of tent caterpillars, but that leaves of faraway trees also change their chemical composition similarly. Warned, as they are, by airborne plant chemicals released from the original trees under attack. Goldenrods signal an attack by a predator through strong chemical communication sent to all other goldenrod neighbors, just as humans warn their neighbors about a nearby fire or flood or crime.
Without any recognizable ears, plants sense sounds. The vibration of a predator insect chewing on its leaves causes a plant to make its own defensive pesticide. Beach evening primrose responds to the sound of honeybees in flight by increasing the sweetness of its nectar to attract them for pollination. Tree roots grow toward the sound of running water, including in pipes, where the roots often burst through causing great difficulties for municipalities. How do the various plants hear these stimulating sounds?
Plants have memory, some anticipating from past experience when a pollinator will show up for the plants’ pollen. Plants express social intelligence: Members of the pea family form relationships with bacteria living in their roots to have the bacteria supply beneficial nitrogen for the plants’ growth. Several kinds of plants provide a home and food for compatible ants who then attack the plants’ ant pests. Perhaps you have you noticed that late summer asters and goldenrod tend to grow as companions. Why? Together—their combined beauty—attracts more pollinators.
In finishing, I express my immense respect for the Indigenous worldview where wind, rocks, air, and rain are our kin, together with plants and nonhuman animals. We, humans, the most recent beings, depend on all of these elder kin; and this awareness, this worldview of connectivity among all beings, is our path back to Earth well-being.
Urgent. It's never been this bad.
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission from the outset was simple. To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It’s never been this bad out there. And it’s never been this hard to keep us going. At the very moment Common Dreams is most needed and doing some of its best and most important work, the threats we face are intensifying. Right now, with just three days to go in our Spring Campaign, we're falling short of our make-or-break goal. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Can you make a gift right now to make sure Common Dreams not only survives but thrives? There is no backup plan or rainy day fund. There is only you. —Craig Brown, Co-founder |
