Culture solves problems much faster than genes ever could
At the University of Maine, two researchers are proposing that humanity has quietly crossed a threshold: the forces shaping who we are and how we survive have shifted from the slow grammar of genetics to the faster, more fluid language of culture. Like the ancient leap from single cells to cooperative organisms, this transition suggests that the tools, institutions, and shared knowledge we build together now do more to determine human fate than the genes we inherit. It is not a claim about progress, but about the changing nature of what it means to be human in a world increasingly shaped by collective invention.
- Cultural evolution is outpacing genetic adaptation at a speed researchers describe as not even close — innovations like eyeglasses and cesarean sections are overriding biological limitations that natural selection would have taken millennia to address.
- The argument challenges a foundational assumption of evolutionary biology, drawing skepticism from scientists who question whether a transition of this magnitude is truly underway in a single species.
- The stakes are disorienting: if where you are born and what systems surround you matter more than your DNA, then the individual human body is no longer the primary unit of evolutionary survival — the group is.
- Waring and Wood are racing to build mathematical models and launch long-term data collection to move their theory from compelling argument to empirical science.
- The researchers caution that understanding this shift is not the same as celebrating it — cultural evolution has produced both remarkable solutions and devastating inequalities, and the transition carries no guarantee of a better outcome.
Two University of Maine researchers — economist Timothy Waring and ecologist Zachary Wood — are making a striking claim: human evolution has fundamentally changed its engine. Where genes once drove adaptation across generations, cultural systems — technologies, institutions, shared knowledge — now do the work faster and more powerfully.
They frame this as a major evolutionary transition, comparable to the emergence of multicellular life or the rise of ultra-cooperative insect colonies. The key difference is speed. When a person learns a skill, adopts a tool, or benefits from a medical innovation, they are inheriting an adaptive advantage without waiting for genetic change. Eyeglasses, cesarean sections, fertility treatments — each one is a cultural workaround to a biological limitation that genetics would have addressed only slowly, if at all.
The deeper implication, as Waring frames it, is a question of what actually shapes a life: the genes you were born with, or the country and institutions surrounding you? Increasingly, the answer points toward culture. Humans are becoming more group-dependent, more reliant on collective systems, and less defined by individual biology.
The researchers are careful not to cast this as progress. Cultural evolution produces both breakthroughs and brutalities, and they explicitly reject any hierarchy between societies. Their hope is that understanding the transition might help humanity navigate it with greater care.
For now, the work is theoretical, and biologists remain skeptical. The team is developing models and planning long-term data collection to test their ideas. But if they are right, the rules of human survival have already quietly changed — and the systems we build together have become more consequential than the biology we inherit.
Two researchers at the University of Maine are arguing that human evolution has fundamentally shifted. It is no longer primarily driven by the genes we inherit, but by the cultural systems we build together—the technologies, institutions, and shared knowledge that spread from person to person, generation to generation.
Timothy Waring, an associate professor of economics and sustainability, and Zachary Wood, a researcher in ecology and environmental sciences, contend that this represents a major evolutionary transition, comparable to the moment single cells merged to form multicellular organisms or when social insects developed their ultra-cooperative colonies. The difference is that this time, humans are the ones undergoing the shift. Culture, they argue, solves adaptive problems at a speed that genetics simply cannot match. When you learn a skill or adopt a technology from someone else, you are inheriting something that helps you survive and thrive—without waiting for your genes to change across generations.
Consider the evidence they point to: eyeglasses allow people with poor vision to function fully in society. Cesarean sections enable women whose bodies cannot deliver vaginally to have children. Fertility treatments help couples who would otherwise remain childless. Each of these innovations overcomes a biological limitation that, in an earlier era, would have reduced someone's chances of survival or reproduction. Genetics would have slowly selected for different traits. Culture simply invented a workaround. "Cultural evolution eats genetic evolution for breakfast, it's not even close," Wood said, emphasizing that this shift has been underway for thousands of years and may be accelerating now.
The implications are profound. Waring posed a question that cuts to the heart of their argument: What matters more for your life outcomes—the genes you were born with, or the country where you live? In the modern world, the answer is increasingly clear. Your access to education, healthcare, technology, and economic opportunity depends far more on the cultural and institutional systems around you than on your genetic inheritance. This means humans are becoming more dependent on collective systems, more group-oriented, more reliant on the knowledge and innovations of others. It is a fundamental change in what it means to be human.
The researchers are careful to note that they are not claiming this represents progress in any moral sense. Evolution produces both elegant solutions and brutal outcomes. Cultural evolution is no exception. Wood emphasized that they are not suggesting wealthy societies with advanced technology are somehow superior to others. Rather, they believe understanding this transition might help humanity navigate it more thoughtfully, potentially avoiding the harshest consequences of cultural-evolutionary competition.
The work remains theoretical for now, though the team is developing mathematical and computer models to test their ideas. They plan to launch a long-term data collection project to gather evidence. Biologists have been skeptical that such a major evolutionary transition is actually occurring in humans, so the burden of proof is substantial. But if Waring and Wood are right, we are living through a pivotal moment in human history—one where the rules of survival and adaptation have fundamentally changed, and where the systems we create together matter more than the biology we inherit.

Culture solves problems much more rapidly than genetic evolution— Timothy Waring, associate professor of economics and sustainability
What matters more for your personal life outcomes, the genes you are born with, or the country where you live?— Timothy Waring
La Conversación del Hearth Otra perspectiva de la historia
When you say cultural evolution is now the dominant force, do you mean genetics has stopped mattering entirely?
No, genetics still matters—it's the foundation. But it's no longer the primary constraint on human outcomes. A person born with genes for poor eyesight faces no real disadvantage anymore because we invented glasses. Genetics set the starting point; culture now determines what you can do with it.
But doesn't this assume everyone has equal access to these cultural innovations? Doesn't inequality complicate the picture?
Absolutely. That's why they emphasize geography and institutions matter so much. Two people with identical genes will have radically different life outcomes depending on whether they're born in a place with functioning schools, healthcare, and economic opportunity. Culture is powerful, but it's not evenly distributed.
You mentioned this has been happening for millennia. What changed recently that made them notice it now?
The acceleration is visible. In the last century alone, we've solved problems—infertility, vision correction, childbirth complications—that would have been evolutionary dead ends for most of human history. The pace of cultural innovation is outpacing anything genetics could do.
Is there a risk in this? If we're all depending on shared systems, what happens if those systems fail?
That's implicit in their caution about not treating this as inevitable progress. Cultural evolution can produce brilliant solutions or catastrophic ones. We're more interdependent than ever, which is powerful but also fragile.
So they're saying we should be more intentional about how we shape these cultural systems?
Exactly. If culture is now the primary driver of human development, then the choices we make about institutions, technology, and knowledge-sharing become evolutionary choices. They matter in ways previous generations couldn't have imagined.
