How the Most Dramatic Genetic Change in Human History Holds the Keys to Vibrant Health.
Coming in 2027…
What if a little-known but remarkable Arctic genetic mutation could reveal a forgotten pathway to ancient America and hold the key to our overall health?
Early American historian Gideon Mailer and metabolic scientist Nicola Hale tell the story of how humanity’s fastest-developed genetic mutation helped protect energy flexibility during the migration from Northeast Asia to the harshest environments of Arctic America. The 6,000-year-old story of ketosis and glucose burning working together is directly relevant to how modern humans process fuel. It provides a plan for reconnecting with our metabolic roots and unlocking the secrets of Arctic survival, leading to improved energy, balance, and longevity.
We live under bright lights that imitate the Arctic summer, when the sun never sets and food is abundant. We believe we’ve finally won the Diet Wars with low-carb Keto plans and appetite suppressants like Ozempic. But beneath those lights, as we carefully balance our carbs and fats, our energy and hormones reflect those of a constant Arctic winter. Too many of us experience severe environmental stresses similar to those that led to humanity’s fastest and most dramatic genetic change, which happened 6,000 years ago in Polar America.
By tracing the appearance of the genetic mutation we name the Arctic Variant, our book tells a story of migration and survival along an overlooked route to North America, long after the famous Ice Age Bering Land Bridge from Northeast Asia had melted. By linking the latest archaeological and genetic discoveries to the science of human energy needs, we demonstrate how the mutation became dominant in its ancient community faster than more well-known mutations in recent human evolutionary history—such as lightening skin to produce Vitamin D from sunlight.
My co-author Nicola was a research scientist at Cambridge before dedicating the last decade to the biochemical and genetic story at the heart of the project that has led to Arctic Signal. Her 2020 peer-reviewed article for Molecular Genetics and Metabolism is titled: “Inuit metabolism revisited: what drove the selective sweep of CPT1a L479?”
Some of our past collaborative work has been cited as evidence in the journal Frontiers in Nutrition, to demonstrate how the United States Food Pyramid recommendations for high carbohydrate and low-fat diets have adhered to suboptimal guidelines that were not always based on evolutionarily sound principles.
Building on these projects, our book uncovers the story of the Arctic Variant, scientifically referred to as the CPT1a L479 variant, which resides on chromosome 11. As the swiftest “Selective Sweep” in history, it emerged between 23,000 and 6,000 years ago solely among the ancestors of Inuit people in Arctic America. Discovered in a living patient in 2001, it has since sparked a debate about whether it was supposedly selected to counteract a fat burning metabolism in a very low carb environment.
After a decade of research—including ancient DNA analysis, review of historical records, archaeological studies, and a thorough synthesis of the biochemical literature – we show how the mutation is better understood as protecting metabolic flexibility in an environment where periodic ketosis complemented glucose metabolism.
Rather than being defined as “for” or “against” ketosis, we show how the mutation reveals a larger story about metabolic flexibility in a healthy low carb framework, overlooked hormonal signaling mechanisms from Omega 3 fats, periodic but not chronic fasting, and the importance of overlooked nerve pathways.
That story sheds light on a forgotten migration to North America that took place long after the Beringia Land Bridge melted.
And we demonstrate how the narrative offers a template for us today to reflect the effects of the mutation.
