Evolution and Devolution of Knowledge: A Tale of Two Biologies

The paradox of modern cognition: gaining specialized scientific expertise while losing fundamental biological wisdom

The Shrinking Naturalist: How Modern Life Is Eroding Our Innate Biological Wisdom

Imagine a world where you could name dozens of plants and animals in your immediate environment, understanding their relationships and uses. For most of human history, this was commonplace—a necessary form of intelligence passed down through generations.

Cognitive Paradox

Despite unprecedented access to scientific information, practical knowledge of the natural world is diminishing 1 .

Two Biologies

Specialized scientific knowledge vs. impoverished public nature literacy creates a concerning divide 1 .

The Rise and Fall of Folkbiological Knowledge

What Is Folkbiology?

Folkbiology represents our innate human capacity to recognize, categorize, and reason about living things. It's the pre-theoretical knowledge that allows us to intuitively understand biological relationships 1 .

"This cognitive framework provides the common ground upon which competing scientific investigations were built throughout human history 1 ."

The Documented Devolution

Groundbreaking research analyzing the Oxford English Dictionary from the 16th through 20th centuries revealed a startling pattern: after centuries of increasing specificity and knowledge about living kinds, the 20th century saw a precipitous decline in the use of biological terms 5 .

Knowledge Loss Across Biological Categories
Comparative Analysis

The decline was specific to biological categories—several non-biological categories continued to evolve and become more sophisticated during the same period 5 .

Technology: +85%
Psychology: +65%
Economics: +80%
Biology: -55%
Context Analysis

When researchers analyzed sentences where biological terms were incidental rather than the main topic, the same decline was evident. This suggests a genuine loss of everyday familiarity with the natural world, not just changing literary conventions 5 .

This isn't merely a change in writing styles but reflects a fundamental shift in human-nature relationships 5 .

Why Losing Nature Knowledge Matters

Cognitive Consequences

Research shows that results on categorization and reasoning from "standard populations" fail to generalize to humanity at large. Our understanding of basic cognitive processes is thus skewed 1 .

This knowledge loss affects child development, yielding misleading results about the relationship between understanding biology and understanding psychology 1 .

Environmental Decision-Making

Groups living in the same habitat can manifest strikingly distinct behaviors, cognitions, and social relations relative to it. The loss of folkbiological knowledge has novel implications for environmental decision making 1 .

When people lack basic understanding of ecological relationships, they struggle to make informed decisions about conservation and resource management 1 .

Reversing the Trend: From Knowledge Devolution to Revival

The documented decline in biological knowledge might seem discouraging, but understanding this trend is the first step toward addressing it.

Early Nature Education

Introducing children to biological concepts before the design stance becomes entrenched

Cultural Integration

Respecting and incorporating indigenous and local ecological knowledge

Citizen Science

Engaging the public in biological monitoring and research initiatives

Urban Nature Planning

Designing cities that facilitate everyday interaction with diverse species

Cognitive Hope

What makes the loss of folkbiological knowledge particularly concerning is that it represents more than just forgetting facts—it signifies the erosion of a fundamental human capacity. The good news is that cognitive capacities, even when neglected, can be revived and retrained 1 .

Conclusion: Bridging the Two Biologies

The tale of two biologies—the specialized knowledge of science and the waning wisdom of everyday nature literacy—represents one of the quiet cognitive revolutions of our time. As we move further into the Anthropocene, recovering our connection to and understanding of the natural world becomes not merely nostalgic but essential 4 .

The Path Forward

The challenge ahead lies in bridging these two biologies—connecting the powerful tools of modern biological science with the engaged, practical understanding that has characterized human relationships with nature throughout most of our history 1 .

Our future may depend on whether we can reverse the devolution of knowledge and forge a new relationship with the living world.

The paradox noted by researchers—that biological science advances while public understanding recedes—need not be our permanent condition. By recognizing the value of both forms of knowledge, we can work toward a future where scientific sophistication and public nature literacy grow together 1 .
