The air we breathe is a profound testament to our interconnectedness, a silent symphony of mutual dependence. With each inhale, we draw in oxygen, a vital gift from the plant kingdom, a product of their photosynthetic artistry. This oxygen embarks on a journey through our bloodstream, a complex exchange where it is traded for carbon dioxide, the very element plants require to sustain themselves. Our exhalations, in turn, nourish the flora around us, completing a cycle that underscores a fundamental truth: what we breathe out, plants breathe in; what plants breathe out, we breathe in. This constant, invisible exchange reveals that the air sustaining us is, in essence, the collective breath of all living beings. We are not isolated entities, but rather integral components of a vast, breathing biosphere, immersed in the world, and the world immersed in us.
This profound interconnectedness extends to our very bodies. Far from being singular, self-contained units, our physical forms are vibrant ecosystems, teeming with a staggering diversity of life. It is estimated that as many as one thousand different species, from bacteria and viruses to fungi and other microorganisms, inhabit our skin, mouths, and digestive tracts. Astonishingly, only about ten percent of our cells carry the human genome; the remaining ninety percent harbor the genetic material of these microbial inhabitants. This complex community, known as the microbiome, is not merely present but essential for our survival, facilitating critical functions such as digestion, metabolism, immune responses, and even neurological processes.
Delving even deeper into our composition, our bodies are comprised of approximately seven octillion atoms. Each of these atoms carries an immense history, forged in the fiery core of an ancestral star billions of years ago before embarking on a cosmic journey to become part of us. This perspective echoes the sentiment of naturalist John Muir, who observed, "When we try to pick out anything by itself, we find it hitched to everything else in the universe."
However, the prevailing narrative of evolution, as commonly understood, often fails to adequately reflect this intricate web of interconnectedness. The very way we conceptualize evolution shapes how we perceive ourselves and our place within the natural world.
The Persistence of the "Red in Tooth and Claw" Narrative
When the concept of evolution is introduced, particularly in early educational contexts, phrases such as "survival of the fittest" and "struggle for existence" frequently come to mind. These terms, rooted in the mid-nineteenth century, tend to evoke a paradigm of relentless competition and inherent selfishness within nature. This viewpoint, often sensationalized as "nature, red in tooth and claw," portrays organisms locked in a perpetual battle for resources, territory, and dominance.
Yet, a significant consensus among contemporary scientists posits that many of the most transformative events in the history of life on Earth were driven not by conflict, but by extensive cooperation and symbiosis. Mutualistic relationships, where different species benefit each other, are demonstrably abundant across the microbial, fungal, plant, and animal kingdoms. Cooperation, therefore, is neither an antithesis to conflict nor an anomaly in the evolutionary process. The enduring question remains: why does the stereotype of a fiercely competitive natural world persist so strongly in both the public and scientific imagination?
The emergence of evolutionary theory in the mid-nineteenth century coincided with the ascendant rise of industrial capitalism. Darwin’s seminal ideas were, in many instances, interpreted through the lens of this burgeoning economic system, resonating with its competitive ethos. This led to the development of Social Darwinism, a pseudoscientific ideology that sought to apply evolutionary principles, such as natural selection, to human societies. Social Darwinism posited that societal progress was intrinsically linked to competition, asserting that those who excelled in the competitive marketplace were inherently more "evolutionarily fit" and superior. Conversely, poverty and failure were attributed to the perceived inferiority of certain individuals or groups. This framework provided a seemingly scientific justification for existing social hierarchies and economic disparities, effectively legitimizing the status quo.
It is a critical point that the phrase "survival of the fittest" was not coined by Charles Darwin himself, but by the influential English sociologist and proponent of Social Darwinism, Herbert Spencer. Spencer, in an effort to align his economic theories with Darwin’s biological principles, suggested that social hierarchy was not only justifiable but also a reflection of the most advanced and resilient societies. Darwin, while more cautious about directly applying his theories to human society, nonetheless offered mechanisms of natural selection that were readily co-opted to support capitalist and imperialist narratives centered on competition and self-interest.
This individualistic, competitive worldview is further reflected in other popular metaphors, such as Richard Dawkins’ concept of the "selfish gene." While a powerful conceptual tool, the popularity of such metaphors can unfortunately lead to a loss of sight of their analogical nature. Dawkins himself has repeatedly clarified that "selfish genes" do not necessarily translate to "selfish individuals." In fact, genes that are "selfish" in an evolutionary sense can drive altruistic behaviors in the organisms that carry them.
Darwin himself emphasized that natural selection was not solely a process of independent organisms vying for supremacy. In his seminal work, On the Origin of Species, he clarified his use of the term "struggle for existence," stating, "I should premise that I use the term Struggle for Existence in a large and metaphorical sense, including dependence of one being on another." (emphasis added). In the concluding paragraphs of the same book, Darwin invoked the image of an "entangled bank" teeming with diverse species of plants, birds, worms, and insects to illustrate this profound interdependence. Years later, in The Descent of Man, he further suggested that sympathy is a fundamental evolutionary force in social animals, positing, "It will have been increased through natural selection; for those communities, which included the greatest number of the most sympathetic members, would flourish best and rear the greatest number of offspring."
Challenging the Competitive Paradigm
The co-option of evolutionary theory into a purely competitive and individualistic framework presented a narrow and often distorted view of Darwin’s work, one that mirrored the prevailing societal trends and ideologies of the time. However, even during this period, various scholars actively challenged this one-sided perspective.
A notable rebuttal came from the Russian anarchist Peter Kropotkin in his influential 1902 book, Mutual Aid: A Factor of Evolution. Kropotkin argued forcefully that cooperation is not only abundant in nature but plays a vital role in the overall well-being of both individuals and societies. He exclaimed, "Don’t compete! . . . Practice mutual aid! That is what Nature teaches us. That is the surest means for giving to each and to all the greatest safety, the best guarantee of existence and progress, bodily, intellectual, and moral." Kropotkin proposed that the contemporary emphasis on competition was anthropocentric, likely a projection of human strivings and failings rather than an accurate depiction of natural processes.
Competition or Cooperation: An Entangled Reality
The question of whether nature is fundamentally competitive or cooperative hinges on how we frame the answer. However, the necessity of choosing one over the other is increasingly being challenged. Animals, such as chimpanzees, are not inherently more violent and competitive than they are peaceful and cooperative. Reassurance behaviors, for instance, tend to increase when the potential for conflict is highest, demonstrating how cooperation and competition are intrinsically intertwined. One often begets the other; competitive challenges frequently necessitate cooperative solutions, and those who cooperate more effectively often compete better. Life, in its essence, requires the skillful management of both competitive and cooperative relationships.
Consider the individuals in your own life with whom you experience the most conflict, and then think of those with whom you cooperate most closely. For many, these lists will overlap significantly. Our most intimate and involved relationships—whether with partners, family, friends, or colleagues—often exemplify the entangled nature of competition and cooperation.
Despite this complex reality, popular literature and media frequently frame human nature as essentially cooperative or competitive, a dichotomy often exemplified by comparisons between bonobos and chimpanzees, our closest living relatives. Those advocating for a more peaceful view of human nature tend to highlight the bonobos’ reputation for "make love not war," while proponents of the "red in tooth and claw" outlook emphasize the stereotype of the aggressive, male-dominated chimpanzee. However, extensive research, including analyses of chimpanzee and bonobo sanctuary communities, indicates that the variation within each species is often greater than the differences between them. For example, behaviors like consolation and sociosexual interactions during consolatory acts, often expected to be more prevalent in bonobos, reveal a far more nuanced pattern. Some chimpanzee communities exhibit more bonobo-like behaviors, and vice-versa, underscoring the fluidity and context-dependency of social behavior.
So, are humans innately hostile and violent, or inherently friendly and peaceful? A glance at current events suggests that the answer is far from straightforward. Humans possess the capacity for both aggression and profound cooperation. It is therefore reasonable to extend this recognition of complex behavioral repertoires to our closest primate relatives, rather than confining them to rigid species stereotypes.
Both competition and cooperation are undeniable driving forces in evolution. The crucial insight is not to prioritize one over the other, but to recognize the intricate interplay between them. The question then becomes: how has the conventional emphasis on competition influenced our scientific approaches and, consequently, our understanding of nature’s deeper workings?
The Subversive Science of Interconnection
Suzanne Simard, a professor of forest ecology at the University of British Columbia, grew up immersed in the ancient forests of Canada, developing an intimate understanding of their complex ecosystems. As a young student in forestry, she was taught a prevailing dogma: forest life was a battleground of competition, with trees locked in a constant struggle for sunlight, water, and nutrients. This competitive view, unfortunately, often sanctioned destructive forestry practices, such as clear-cutting and the establishment of monoculture plantations. The underlying philosophy of "free-to-grow" initiatives was that by eliminating competition, newly planted trees would thrive.
However, Simard observed that trees in these plantations were more susceptible to disease and climatic stress compared to their counterparts in old-growth forests. She noted that when neighboring species like paper birch were removed, Douglas fir saplings often faltered and died, despite ample space and resources. Her research eventually unearthed a hidden underground support system.
Simard’s groundbreaking doctoral research, published in Nature in 1997, revealed that birch and fir trees engage in a collaborative exchange of carbon through underground fungal networks connecting their root systems, famously dubbed the "wood wide web." Her findings demonstrated that birch trees, when shading fir trees, would transfer carbon to them, effectively compensating for the reduced light. This research directly challenged the long-held view of species as perpetually competing entities.
Subsequent work by Simard and her students has illuminated the extensive mycorrhizal networks that connect trees within a forest, often orchestrated by older "mother" or "hub" trees that share nutrients with younger saplings. These networks not only facilitate nutrient exchange but also aid in protecting plants from pests and diseases. However, the system is not without its complexities; plants can also extract resources from others through these networks, and some can even distribute toxic substances to inhibit neighboring plants.
Despite her findings appearing in a top scientific journal, Simard faced significant backlash from a male-dominated forestry establishment. Her research, which challenged entrenched beliefs about plant competition, was sometimes dismissed as overly "girly." Skepticism persists, partly due to the deeply ingrained belief that humans are unique in their capacity for such elaborate cooperation. Furthermore, the narrative that trees always benefit from these networks, often amplified by media, overlooks the nuanced and sometimes competitive aspects of these relationships. The forest, as Simard emphasizes, is a dynamic ecosystem characterized by both collaboration and competition, an intricate interplay that defines all living, evolving relationships.
Simard has expressed frustration with the tendency of Western science to overlook these interconnected relationships, noting, "We don’t ask good questions about the interconnectedness of the forest, because we’re all trained as reductionists. We pick it apart and study one process at a time, even though we know these processes don’t happen in isolation."
This interconnected ecological perspective has long been a cornerstone of many animist and Indigenous worldviews, emphasizing reciprocity and relationality. Modern scientific findings increasingly align with these traditional perspectives. Throughout Western history, numerous scientists have defied reductionism, embracing a holistic approach. Charles Darwin himself viewed nature as a densely entangled web of subjects, not merely a collection of discrete objects. The German philosopher Johann Wolfgang von Goethe championed a holistic approach, stating, "In nature we never see anything isolated, but everything in connection with something else which is before it, beside it, under it, and over it." Similarly, Alexander von Humboldt believed in studying the intricate relationships between natural elements, asserting, "Everything is interaction and reciprocal."
The development of ecology in the late nineteenth century—the study of relationships among living beings and their environments—offered a formal challenge to scientific reductionism. Ecology earned the nickname "the subversive science" for its capacity to compel humans to re-evaluate their place in the natural world. A notable offshoot, deep ecology, conceived by Norwegian philosopher Arne Naess in the 1970s, explicitly rejects anthropocentrism, championing the intrinsic value of all living beings and acknowledging the profound interconnectedness of existence.
The intricate symbiosis between fungi and trees is so profound that some scientists propose viewing them not as separate organisms, but as components of an integrated forest entity. From the perspective of deep ecology, all beings are deeply entangled, with humans being no exception. This raises a fundamental question: where does nature end, and where do we begin?
A Wide and Deep Net of Symbiosis
The very language we use to describe the natural world can reinforce a dualistic understanding, subtly suggesting that "nature" exists somewhere beyond ourselves, distinct from human culture and society. This framing, while convenient, can obscure the profound integration of all life.
The humble lichen offers a compelling illustration of this interconnectedness. These hardy organisms, often found adorning trees and rocks, were once categorized as plants due to their photosynthetic capabilities. However, in the late nineteenth century, scientists discovered that lichens are, in fact, collaborations between fungi and algae. The fungus provides structure, nutrient absorption, and water retention, while the alga, through photosynthesis, supplies essential energy. This partnership allows lichens to thrive in extreme environments, demonstrating that a lichen is not a singular entity but a composite being, a testament to the power of symbiosis.
It was the study of lichens that led botanist Albert Frank to coin the term "symbiosis" in the late 1870s, referring to close, long-term physical associations between different species. When these associations benefit all parties involved, they are classified as mutualism. Since its introduction, symbiosis has been recognized as a fundamental feature of life, playing an essential role in the development and survival of nearly every organism.
The vibrant ecosystems of coral reefs, for instance, depend on a symbiotic relationship with microscopic algae living within their tissues. When ocean temperatures rise due to global warming, corals expel these algae, leading to a loss of color and nutrients—a phenomenon known as coral bleaching. This illustrates that it is not simply the elevated temperature, but the disruption of the symbiotic relationship itself that causes the damage.
Our own cells are powered by mitochondria, organelles that originated from free-living bacteria engulfed by an ancestral host cell approximately 1.5 billion years ago. Instead of being digested, these bacteria formed a mutually beneficial relationship, providing energy in exchange for a protected environment and nutrients. This process, known as endosymbiosis, was elegantly explained by evolutionary biologist Lynn Margulis. Her theory proposed that complex lifeforms, including animals, plants, and fungi, evolved from simpler symbiotic relationships. Margulis’s work directly challenged the prevailing emphasis on competition, asserting, "The view of evolution as a chronic bloody competition among individuals and species, a popular distortion of Darwin’s notion of ‘survival of the fittest,’ dissolves before a new view of continual cooperation, strong interaction, and mutual dependence among life forms. Life did not take over the globe by combat, but by networking. Life forms multiplied and complexified by co-opting others, not just by killing them."
Margulis’s theory, initially met with skepticism and rejection by the scientific establishment, is now a cornerstone of evolutionary biology, explaining the origin of eukaryotic cells. It underscores that nature is not a zero-sum game; one entity’s gain is not necessarily another’s loss.
The Web of Life: Beyond the Evolutionary Tree
Lynn Margulis’s endosymbiotic theory offers a paradigm shift from the traditional evolutionary tree, which depicts species diverging and branching off independently. Instead, her work emphasizes how organisms readily interact and influence one another, forming a complex web or net. Building on this, anthropologists Carla Hustak and Natasha Myers introduced the term "involution," suggesting a "rolling, curling, turning inwards" where living beings continuously intertwine through processes like symbiosis. This contrasts with "evolution," which implies outward progression. The image of an evolutionary tree, with its emphasis on individual branches, may itself reflect a cultural bias towards individualism and competition. We are not standing at the tip of a twig, but rather enmeshed in a wide and deep net of symbiotic relations.
Our co-evolution with plants, for example, has shaped our sensory experiences and dietary preferences. The delectable flavors of ripe fruits are a clever plant strategy to entice animals like us to consume them, thereby facilitating seed dispersal. This long-standing partnership has led to an astonishing diversity of fruit types, with different plant species adapting to the specific habits of various animals. Avocado plants, with their large pits, originally evolved alongside megafauna capable of dispersing their seeds. Our very eyesight, attuned to the vibrant colors of fruits and flowers, is a product of this shared evolutionary journey, enabling us to easily locate edible plants. As cultural ecologist David Abram eloquently states, "We are human only in contact, and conviviality, with what is not human."
Rethinking the "Biological Individual"
Advances in microbial sciences have further blurred the lines of what constitutes an individual organism. It is no longer tenable to view "you" as entirely distinct from the microbial communities inhabiting your body. You are, in essence, a "holobiont"—a whole ecosystem within yourself. By cell count, the vast majority of your body is not strictly "yours"; it hosts trillions of microorganisms, outnumbering human cells by a ratio of ten to one. The number of bacteria in your gut alone surpasses the number of stars in our galaxy, and those in your mouth are comparable to the total number of humans who have ever lived. Collectively, these microbes weigh approximately three pounds, equivalent to the mass of an average human brain, and wield a comparable, if not greater, influence.
Research indicates that the health of your gut flora is predictive of your ability to solve complex memory and learning tasks. Your mood, too, is influenced by the composition of your gut bacteria, giving credence to the colloquial notion of a "gut feeling." Interventions that alter the gut microbiome, such as probiotics, have shown promise in regulating mood and behavior associated with depression and anxiety.
Our immune system develops in constant dialogue with our microbiota, which helps mediate our responses to other organisms, influencing how we fight disease and derive nutrients from our environment. Microbes extend the capabilities of their hosts, which rely on this symbiotic relationship for their very existence. For instance, cows cannot digest grass on their own, but their microbial populations can. This intricate co-evolution has led to specialized bacterial strains adapted to specific animal niches; indeed, 90 percent of bacterial species found in termite guts are unique to that environment. This also highlights a poignant fact: for every animal species that goes extinct, a potentially unknown number of highly specialized bacterial lineages disappear with it.
These findings fundamentally challenge the concept of a discrete, autonomous "self." Our microbiome dynamically shapes who we are in ways we are only beginning to comprehend. While not all aspects of this relationship are harmonious—interests of symbionts can diverge—the interdependence is undeniable. A 2012 paper published in The University of Chicago Press Journals, titled "A Symbiotic View of Life: We Have Never Been Individuals," synthesized these discoveries, arguing for a re-evaluation of the "biological individual" in favor of recognizing interspecies interdependences. The article boldly concluded, "For animals, as well as plants, there have never been individuals. This new paradigm for biology asks new questions and seeks new relationships among the different living entities on Earth. We are all lichens."
The "God Species" and the Illusion of Dominance
A poignant cartoon by Dan Piraro, titled "The Year 3011," depicts two ants contemplating the ruins of human civilization, with one ant questioning the "success" of a species that eliminates itself in a mere few million years. Despite humanity’s apparent evolutionary "success," it is plausible that other lifeforms, such as ants and lichens, will endure long after our tenure on Earth. Science fiction often imagines a future where other species dominate the planet in the aftermath of human self-destruction. The question arises: would these future dominant species exert their influence to the same extent as humanity?
As previously noted, evolution is not solely characterized by ruthless competition; cooperation and symbiosis have been equally significant drivers throughout life’s history. Yet, prominent contemporary thinkers continue to equate evolutionary "success" with dominance over the rest of nature. An article in Scientific American, titled "What Makes Humans Different Than Any Other Species," exemplifies this perspective, questioning humanity’s success in populating virtually every corner of the planet and achieving remarkable technological feats, despite sharing nearly 99 percent of its genetic material with chimpanzees. While acknowledging humanity’s capacity to manipulate its environment, it is crucial to avoid framing endeavors like nuclear weapon development as indicators of species "success."
Even in our capacity to manipulate environments, we are not without precedent. Cyanobacteria, among the earliest photosynthesizing organisms, dramatically altered Earth’s atmosphere during the Great Oxidation Event. Billions of years ago, they set the stage for life as we know it, causing the extinction of anaerobic organisms and paving the way for the evolution of aerobic lifeforms.
Zoologist Luis Villazon, in a BBC interview, argues that humanity’s claim to ecological dominance is based on self-selected criteria. He notes that ants outnumber us, trees outlive us, and fungi outweigh us. Bacteria, he contends, win on all counts: they existed billions of years before us, created our oxygen-rich atmosphere, collectively outnumber us by an astronomical margin, and their total mass exceeds that of all animals combined. Measuring evolutionary success solely by dominance, particularly a form of dominance where humans happen to excel, is a self-serving perspective.
Consider mosses, which have thrived for over three hundred million years, far longer than Homo sapiens. Their remarkable longevity is attributed not to competitive prowess, but to collaboration—building soil, purifying water, and creating habitats for other forest creatures. This raises the question: what if cooperation, longevity, resilience, and the ability to sustain thriving interspecies communities were the true metrics of evolutionary "success"?
The notion of a natural hierarchy, with humans at the top of the food chain, is a simplistic, linear view. More realistic representations, such as food webs, depict interconnected ecosystems where organisms at different trophic levels mutually influence one another. From a producer standpoint, plants are at the apex, possessing the miraculous ability to convert sunlight into sustenance for animals. Without them, our existence would be inconceivable. Similarly, fungi play a crucial role at the top of the decomposition chain, recycling organic matter and promoting soil fertility. Establishing hierarchies based solely on consumption, a value deeply embedded in capitalist culture, overlooks the multifaceted and non-hierarchical relationships present in nature.
The Fallibility of "Inevitability"
The prevailing view of evolution, emphasizing competition for resources, can lead to the perception of human ascendancy as a logical and inevitable outcome of natural selection. Consequently, the ecological crisis is sometimes framed as an unavoidable consequence of this process, the logical result of humans acting in their own self-interest. This "inevitability narrative" suggests that inherent psychological barriers prevent humans from effectively addressing issues like climate change.
However, this narrative overlooks the profound variation in human cultural responses to climate change. There is no universal human response to this issue. Framing climate inaction as an inevitable part of human nature serves to justify the status quo and shifts responsibility from systemic issues to individual shortcomings.
The discussion around solar geoengineering, a proposed method to counteract global warming by reflecting sunlight, highlights the complexities and potential pitfalls of technological interventions. While such technologies might offer a rapid solution to rising temperatures, they also raise concerns about unintended consequences, such as impacts on pollinators, the potential for a "moral hazard" that disincentivizes emission reductions, and the unequal distribution of risks across different countries. Crucially, many of these proposed solutions, while ostensibly aimed at environmental protection, paradoxically reinforce the very mindset of human dominance over nature that has contributed to the crisis in the first place.
Elizabeth Kolbert’s Under a White Sky critically examines human attempts to actively manage and control natural systems. Her work reveals how even well-intentioned interventions often yield unintended consequences, disrupting ecosystems and global weather patterns, leading to a cascade of complex problems requiring ever more inventive, and potentially problematic, solutions. The more we attempt to defy nature, the more our limitations become apparent.
Darwin’s "entangled bank" serves as a potent reminder that humans are but one species within a vast, interconnected web of life. In these intricate networks of cause and effect, unintended consequences are an almost inevitable outcome of human interventions. As ecologist Frank Egler observed, "Nature is not only more complex than we think. It’s more complex than we can think." Consequently, human technology frequently struggles to replicate the invaluable capacities of intact, healthy ecosystems.
This does not negate the role of technological innovation in addressing ecological degradation. However, it is imperative that we first question the underlying principles of human dominion and sovereignty over nature. Many technofixes, deployed in the name of saving the environment, often reflect the very human exceptionalism that has driven its destruction. A truly sustainable path forward requires addressing the root causes of our ecological challenges, rather than merely treating the symptoms.
Conclusion: Embracing Interconnection for a Sustainable Future
Our anthropocentric, individualistic, and competitive view of life fosters a psychological detachment from the natural world. This detachment diminishes our understanding of ourselves and nature, limits our scientific inquiry, and reduces other species—and even entire planets—to mere commodities for exploitation. The ultimate consequence of this approach is self-inflicted harm. As Rachel Carson poignantly noted in Silent Spring, "But man is a part of nature, and his war against nature is inevitably a war against himself." By embracing a more holistic and interconnected understanding of life, we can begin to chart a course towards genuine sustainability and a more harmonious coexistence with the intricate web of life that sustains us all.
