By almost every objective measure, this is the best time in human history to be alive.
We live longer. Fewer children die in infancy. War is rarer than it has ever been. Food is more abundant. Billions of people now have access to clean water, sanitation, education, and safety from predators. These are no longer privileges. They are baseline expectations for a large portion of humanity.
And yet.
Depression, anxiety, and loneliness are skyrocketing. Over a billion people live with chronic health conditions that were virtually unknown a century ago. Type 2 diabetes has exploded to epidemic proportions, even in children. Fertility is declining. Suicide is now among the leading causes of death in many countries.
This is not just strange. It is deeply disturbing.
How is it possible that we are safer, wealthier, and more comfortable than at any point in history, and simultaneously more miserable, more disconnected, and more sick?
That question changed the trajectory of my life. It took me from corporate boardrooms to barefoot treks through East Africa. Over the past 30 years, I have studied health, behavior, and evolutionary history. I have spent 15 of those years visiting one of the last true hunter-gatherer tribes on Earth, the Hadza, who made me an honorary member of their tribe.
And what I came to understand rewired the way I think about everything.
The Real Cause of Our Modern Struggles
The answer is not laziness. It is not bad genetics. It is not some collective moral failing.
The answer is evolutionary mismatch.
We are trying to live modern lives in bodies, minds, and emotional systems that were designed for the Stone Age.
For 99.9% of our evolutionary history, we lived in small tribal groups. We moved daily. We ate whole, seasonal foods. We fasted naturally. We bonded deeply. We slept in sync with the sun. We made decisions face to face. We did not have constant access to sugar, screens, or mass media.
We were wild. And we were well adapted to that life.
But almost everything has changed in the last few hundred years. Some of it in the last few decades. Now we live in an environment our biology simply does not understand: artificial light, ultra-processed food, algorithmic stimulation, isolated nuclear families, and an attention economy that was engineered to exploit our evolutionary vulnerabilities.
The result is stress, sickness, disconnection, and confusion.
What looks like a mental health crisis, a chronic disease epidemic, or global burnout may actually be one underlying issue with many symptoms. Our environment has changed faster than we have. This is the core tension I explore in The Gap book, and it is the lens through which nearly every modern struggle starts to make sense.
What If Type 2 Diabetes Is Not a Disease?
Let me give you one concrete example.
For decades we have been told that Type 2 diabetes is a lifelong, progressive disease that must be managed with medication. But what if that framing is wrong?
What if Type 2 diabetes is actually a repetitive stress injury? The predictable result of long-term mismatch between our dietary environment and the metabolic systems we evolved?
That is the premise behind PostDiabetic, a book I co-authored with Dr. Ruben Ruiz. He reversed his own Type 2 diabetes and got off nine of his ten medications. Not through pharmaceutical intervention. Through realigning with our evolutionary biology.
He changed what he ate. When he ate. How he moved. How he slept. And the results were profound.
We have since helped thousands of others do the same. Not by treating symptoms, but by addressing the cause: evolutionary mismatch. This is what real behavior change looks like. Not willpower. Not restriction. Realignment.
From Personal to Global
Mismatch theory is not just about diet or diabetes.
It applies to nearly every modern challenge:
- Personal: burnout, anxiety, chronic illness, fertility struggles
- Family: disconnection, screen time battles, sleep disorders
- Social: addiction, loneliness, polarization
- Global: unsustainable economies, ecological collapse, political division
The more you understand evolutionary mismatch, the more clearly you see that many of our most frustrating problems are not mysterious. They are predictable. And the solutions are not always complicated. They are often just misaligned.
We keep trying to solve ancient biological problems with modern technological fixes. More apps. More medications. More productivity systems. More diets. And we wonder why the needle barely moves.
The real leverage is not in adding more complexity. It is in understanding the mismatch and closing the gap between how we live and how we evolved to live.
Where This Leads
If you find yourself nodding along, you are not alone. Millions of people feel the tension between their modern lifestyle and something deeper that they cannot quite name. That tension is the Evolution Gap. And once you see it, you cannot unsee it.
The good news is that closing the gap does not require moving to the wilderness or abandoning modern life. It requires understanding where the friction points are and making deliberate adjustments. Sometimes small ones. Sometimes profound ones.
This is the work I have devoted my life to. Whether it is through health & wellness programs like WILDFIT, keynote presentations on stages around the world, or the books and frameworks I have developed over three decades, the throughline is always the same: help people understand the mismatch so they can stop fighting their biology and start working with it.
Because the real question is not "Why is there so much suffering?"
The real question is: "Now that we understand the cause, what are we going to do about it?"
Frequently Asked Questions
The paradox is explained by evolutionary mismatch. Our bodies and minds evolved for small tribal groups, natural movement, whole foods, and deep social bonds. Modern life delivers artificial light, ultra-processed food, algorithmic stimulation, and social isolation instead. The gap between our biology and our environment produces stress, anxiety, and depression as predictable symptoms, not mysterious diseases.
The Evolution Gap is the growing distance between the environment our biology was designed for and the environment we actually live in. For 99.9% of human history we lived as hunter-gatherers. Almost everything about modern life, from diet to sleep to social structure, has changed faster than our bodies can adapt. That gap drives chronic disease, mental health struggles, and widespread disconnection.
Growing evidence and thousands of real-world cases suggest that Type 2 diabetes can often be reversed by addressing the underlying evolutionary mismatch rather than just managing symptoms with medication. Changes to diet, meal timing, movement, and sleep that realign with our evolutionary biology have helped many people normalize blood sugar and reduce or eliminate medications, as documented in the book PostDiabetic.
