What If Evolution Selects Relationships, Not Just Organisms?

The Living Field Hypothesis by Carol Walden
An Introduction to The Living Field Hypothesis
For years, I have been circling around a question…
What if evolution has not only been selecting organisms, but relationships?
We are accustomed to thinking about evolution in terms of individual living things, with organisms surviving, reproducing and passing their characteristics to the next generation as life gradually adapts over immense spans of time. Yet the more closely I have looked at the natural world, the more incomplete that picture has begun to feel, because no living thing truly exists in isolation.
A tree lives in relationship with fungi beneath the soil, microorganisms around its roots, insects among its leaves, birds in its branches, animals that disperse its seeds, neighbouring plants, rainfall, sunlight and the atmosphere itself. A forest, therefore, is not simply a collection of trees standing together, but an extraordinarily complex living network created by the relationships between them.
The same pattern appears almost everywhere we look. Corals depend upon intimate partnerships with microscopic algae, flowering plants and pollinators have influenced one another across evolutionary time, and fungi and plant roots exchange nutrients beneath our feet. Animals alter landscapes, landscapes influence waterways, waterways create habitats, and those habitats support communities of life that alter the landscape again.
Even our own bodies are communities, living in continual relationship with trillions of microorganisms that participate in processes essential to our health and survival. Again and again, life appears to become more resilient, complex and capable through relationship.
This led me to wonder whether some of the great advances of evolution might arise not simply because individual organisms become better adapted, but because new relationships become possible between them.
This question lies at the heart of what I call The Living Field Hypothesis, which proposes that the resilience, complexity and evolutionary potential of living systems may arise not simply from the organisms within them, but from the richness, diversity and coherence of the relationships connecting them.
Competition, predation, disease, scarcity and death remain part of the evolutionary story, but they are not the whole story. Cooperation, symbiosis, communication, reciprocity and interdependence are also woven deeply into the history of life, and once we begin looking through the lens of relationship, another possibility emerges.
Perhaps the health of a living system depends not only upon how many species it contains, but upon the richness and resilience of the relationships between them.
A woodland can still contain trees while many of its ecological relationships are collapsing, just as a river may continue to flow while the intricate web of life it once supported is disappearing. Species can remain present long after some of the relationships that sustained the larger system have been broken, while restoring an important relationship can sometimes initiate changes that ripple throughout an entire ecosystem.
Seen this way, conservation becomes not only a question of which species we need to save, but also which relationships we need to restore.
This leads inevitably to another question, and perhaps the one that matters most to us: What is the human role within those relationships?
Much environmental thinking understandably concentrates on reducing the damage humans cause through lowering our ecological footprint, consuming fewer resources, producing less waste and interfering less destructively with natural systems. These things matter enormously, but I wonder whether our ambition could extend beyond simply becoming less harmful.
Humans are extraordinarily powerful participants in ecological systems. We alter landscapes, redirect water, cultivate plants, move species, build settlements and influence the conditions under which countless other organisms live. That power can impoverish living systems, but it can also be used consciously to restore and enrich them.
Regenerative agriculture, habitat restoration, wildlife corridors, ecological gardening, living architecture and the restoration of damaged waterways all suggest that human activity can create new possibilities for other forms of life.
This brings me to a question I find far more hopeful than simply asking how much damage we can prevent:
How much life can flourish because we are here?
Imagine designing a garden, farm, town or city around that question, measuring success not only by what humans produce or consume, but by the relationships our presence makes possible. We might create landscapes with more pollinators, healthier soils, cleaner waterways, greater biodiversity and connected habitats, while building human communities that understand themselves as participants within living systems rather than separate from them.
Perhaps our task is not to remove ourselves from the Living World, but to learn how to belong within it.
That possibility is where The Living Field Hypothesis begins.
It is not presented as an established scientific theory, but as a framework for inquiry that brings together ideas from ecology, evolutionary biology, systems science and our growing understanding of the extraordinary interconnectedness of life.
Beneath it lies a deceptively simple proposition: life may evolve not only through what organisms become, but through the relationships they become capable of creating.
If that is true, perhaps one of the most important questions we can ask about the future is not simply what life will evolve next, but what life might become capable of when we learn to strengthen the relationships between us.
