Our ability to live for many decades is often viewed as a modern luxury made possible by clean water, improved living conditions, and advances in medicine. Yet, human longevity is actually part of our deep evolutionary history. The long-standing belief that life in the past was “nasty, brutish, and short” is a widespread misconception—one rooted in misleading averages and often repeated in textbooks and popular media.
In his book “Seven Decades: How We Evolved to Live Longer”, anthropologist Professor Michael Gurven challenges this myth. Drawing on extensive fieldwork, he presents compelling evidence that the capacity for long life first emerged among our hunting and gathering ancestors and argues that the human body is fundamentally designed to function for roughly seven decades. Combining vivid storytelling with rigorous science, Gurven shares insights from years of research among Indigenous societies whose diets and traditional ways of living more closely resemble how humans lived before industrialization. These communities, he shows, experience far lower rates of chronic diseases of aging—such as heart disease, dementia, and diabetes—than populations in industrialized nations.
In this episode of Bridging the Gaps, I speak with Professor Michael Gurven, Distinguished Professor of Anthropology at the University of California, Santa Barbara. For more than twenty years, he has worked closely with Indigenous groups in South America to better understand how traditional lifestyles can shed light on the evolution of human behavior, health, and psychology. His research uses an evolutionary framework to help explain modern health challenges and the origins of chronic diseases.
Our conversation offers a detailed exploration of the book and the science behind it. We begin by examining the myth that ancient people rarely reached old age, discussing how misleading averages have shaped this false narrative and why it is important to correct it. We then talk about a central idea in the book: that each stage of human life has an evolutionary purpose, and our bodies and minds have been shaped accordingly.
Another major theme is the evolutionary significance of post-reproductive life. While some biologists have argued that life after reproduction has no adaptive function, Gurven’s work shows that midlife and elderhood evolved for meaningful reasons and contribute to group survival.
At this point, the discussion turns to his fieldwork—what it is like to work with Indigenous communities, the unique challenges of this research, and how these challenges are addressed in study design and implementation. We then explore key findings from his work, including results that challenge assumptions in modern medicine. Gurven explains what these insights can teach us about improving healthcare and rethinking aging in contemporary societies.
Finally, we discuss the book’s broader message: that by understanding our evolutionary past, we can gain powerful new perspectives on aging, health, and what it means to live a long, meaningful, and productive life.
This conversation is wide-ranging, thorough, and deeply informative.

“Evolutionary Intelligence: How Technology Will Make Us Smarter” with Professor W. Russell Neuman
Artificial intelligence (AI) has emerged as one of the most remarkable advancements of our time. It is a powerful evolving technology that has transformed the way we interact with machines and perceive the capabilities of computer systems. However, with this newfound power comes a natural apprehension. There is a noticeable fear surrounding the unintentional consequences and unintended implications of Artificial Intelligence. As this technology becomes increasingly integrated into our daily lives, the question is: how justified are our fears and just how tangible, and how real is the threat posed by this revolutionary technology? Perhaps, the underlying cause of these fears is our tendency to unjustifiably attribute human traits to the machines we may construct.
A compelling new perspective suggests that human intelligence will evolve alongside digital technology, leading to a transformative coevolution of human and artificial intelligence. This augmented intelligence will reshape our thinking and behaviour. In his recent book “Evolutionary Intelligence: How Technology Will Make Us Smarter” Professor W. Russell Neuman offers a remarkably optimistic perspective where computational intelligence not only addresses the well-known limitations of human judgement but also enhances decision-making capabilities and expands our capacity for action. In this episode of Bridging the Gaps, I speak with Professor W. Russell Neuman. We discuss how our future depends on our ability to computationally compensate for the limitations of the human cognitive system. We explore Neuman’s viewpoint that “if intelligence is the capacity to match means with ends, then augmented intelligence can offer the ability to adapt to changing environments as we face the ultimate challenge of long-term survival”. Professor Neuman's distinctive approach to explain complex concepts through narratives and anecdotes adds an engaging layer of interest to this discussion. This highly informative discussion makes a powerful argument for the continued coexistence of humans and their machines.
W. Russell Neuman is Professor of Media Technology at New York University. He is a specialist in new media and digital education. He is a founding faculty of the MIT Media Lab. He served as a Senior Policy Analyst in the White House Office of Science and Technology Policy, working in the areas of information technology, broadband policy, and technologies for border security.
