How Culture Wins Over Genetics in Driving Human Evolution: Insights from Researchers

Researchers at the University of Maine are exploring a fascinating idea: human evolution might now be driven more by culture than by genetics. Timothy M. Waring, an associate professor of economics and sustainability, and his colleague Zachary T. Wood argue that cultural practices are changing how we adapt and evolve.

In their recent paper published in BioScience, they suggest that cultural evolution is outpacing genetic evolution. Waring explains, “When we learn skills or ideas from each other, we inherit useful cultural practices.” These practices, such as farming or legal systems, can spread much faster than genetic changes. This trend may reshape humanity for thousands of years.

Culture vs. Genetics

Wood states, “Cultural evolution eats genetic evolution for breakfast.” In today’s world, cultural solutions often solve problems more quickly. Consider how eyeglasses fix vision problems that once would have relied on natural selection. Medical advances like cesarean sections allow people to survive and have children in ways that genes alone couldn’t manage.

Waring poses an intriguing question: Is your well-being determined by your genes or where you live? He believes that, increasingly, our success hinges on our society and cultural systems rather than our individual biology.

The Shift Toward Group Dependence

The researchers note that cultural adaptation often favors group solutions. For example, improvements in health and longevity largely come from collective efforts, like healthcare systems or education, rather than individual traits. This shift might mean we’re evolving to rely on one another more than ever.

Waring and Wood argue this cultural transition may also change the definition of what it means to be human. If we continue evolving to depend on culture, our individuality may transform into a more group-oriented context. This echoes past evolutionary milestones, like the transition from single-celled organisms to multicellular life, signaling a profound shift in how life adapts and reproduces.

Looking Ahead

The researchers emphasize their theory can be tested. They plan to gather long-term data to study this cultural evolution. They acknowledge that cultural evolution isn’t inherently good or bad; it can lead to both helpful solutions and harsh outcomes.

As they delve deeper into this dynamic, they aim to harness insights about human evolution to promote positive social change. Waring believes our future as individuals—and as a species—might increasingly depend on our societies’ adaptability and strength. “The next stage of human evolution may be found in the stories and systems we create together,” he asserts.

Recent studies back this shift. A 2023 survey by the Pew Research Center shows that over 70% of people believe access to technology significantly impacts their quality of life today, further supporting Waring and Wood’s findings.
