What Biology Reveals About Us, Our World, and Our Dreams
Exploring the fascinating insights from Gottfried Schatz's interdisciplinary journey through biochemistry, evolution, and the mysteries of life
Begin ExplorationWhere do we come from? Is our destiny written in the genes we inherit? Do we all see the same blue color when we look at the sky? These universal questions find surprising, lucid answers in Gottfried "Jeff" Schatz's A Matter of Wonder: What Biology Reveals About Us, Our World, and Our Dreams 1 .
This collection of elegantly written essays takes readers on a fascinating journey across scientific disciplines, proving that the key to understanding life is no dry endeavor and certainly not devoid of beauty 1 .
Schatz, a world-renowned biochemist and co-discoverer of mitochondrial DNA, was also a professional violinist—a unique blend of talents that informed his broad perspective on science and the arts . His book, originally a series of articles for a Swiss newspaper, offers thought-provoking highlights on topics ranging from mitochondria and intestinal bacteria to circadian rhythms and the twilight of iron, all within a remarkably accessible framework .

Schatz's groundbreaking work on mitochondrial DNA gives him unique authority to discuss these cellular powerhouses. He reveals how mitochondria are far more than simple energy producers; they are dynamic entities with their own genetic material that play surprising roles in our health and aging 1 .
He illustrates their importance through compelling examples, such as a woman with overactive mitochondria who was constantly hot and sweating, even on cold days, and who burned through food at an astonishing rate .
One of the most fascinating themes in Schatz's work is how Earth's ancient history is written into our present-day biology. He explains that in the early, oxygen-poor oceans, microorganisms evolved proteins bound to cobalt, nickel, iron, and manganese .
When oxygen levels rose, sulfur eroded from rocks and caused most of these elements to precipitate . This historical shift explains our modern biological dependency on vitamin B12.
Schatz had a particular talent for highlighting biological paradoxes that we often overlook. He notes the oddity that iron deficiency represents a common human problem despite the abundance of iron on Earth .
The explanation reveals much about biological systems: animals cannot extract iron directly from minerals but must rely on eating plants that have absorbed it, creating a dependency chain that limits our access to this crucial element .
While Schatz's book doesn't detail traditional laboratory experiments, it presents a compelling narrative of what might be called "evolution's great experiment"—how life adapted to Earth's changing chemistry. The vitamin B12 story represents a crucial case study of this process .
Primordial oceans were oxygen-poor, allowing microorganisms to freely use cobalt, nickel, iron, and manganese in their protein structures .
Rising oxygen levels caused sulfur to erode from rocks, leading to the precipitation of most cobalt, nickel, iron, and manganese from ocean waters .
Microorganisms evolved new proteins using zinc and copper, which remained available .
The ability to synthesize cobalamin (vitamin B12) became restricted to only certain bacteria, while all animals remained dependent on it for crucial brain functions .
This natural experiment resulted in what we might call "evolutionary baggage"—biological dependencies that persist despite changing environmental conditions.
The most significant finding is that our brain function depends on a chemical relationship with bacteria that represents a direct link to Earth's primordial past .
| Evolutionary Stage | Environmental Conditions | Biological Adaptation | Modern Manifestation |
|---|---|---|---|
| Early Oceans | Oxygen-poor waters | Proteins using cobalt, nickel, iron, manganese | Ancient metabolic pathways |
| Great Oxidation Event | Rising oxygen, sulfur release | Precipitation of key metals | Loss of accessible cobalt |
| Biological Shift | Changed availability of elements | New proteins using zinc, copper | Modern enzyme varieties |
| Specialization | Stabilized new conditions | Only certain bacteria retain B12 synthesis | Our dependency on gut bacteria and dietary sources |
Schatz's work, particularly his discovery of mitochondrial DNA, relied on various biochemical tools and natural systems that reveal life's complexities.
| Tool/Element | Primary Function | Biological Significance |
|---|---|---|
| Mitochondrial DNA | Genetic material of mitochondria | Enables study of maternal inheritance, evolutionary relationships, and energy metabolism disorders |
| Cobalamin (Vitamin B12) | Cobalt-containing enzyme cofactor | Critical for understanding brain function and evolutionary dependencies between animals and bacteria |
| Iron Compounds | Oxygen transport, energy production | Reveals biological limitations in nutrient absorption and metabolic adaptations |
| Retroviral Vectors | Gene delivery mechanism | Allows study of genetic expression and potential gene therapies |
| Intestinal Bacteria | Symbiotic microorganisms | Model system for understanding host-microbe relationships essential for health |

What makes Schatz's approach distinctive is his resistance to reductionist thinking. While he acknowledges the importance of understanding life's chemistry, he consistently emphasizes that this understanding must be enriched by perspectives from philosophy, cultural history, and art 1 .
This perspective represents what some modern biologists call "poetic ecology"—an approach that regards feeling and expression as necessary dimensions of existential reality, not as irrelevant epiphenomena 2 . Schatz's work similarly bridges the gap between rigorous science and the deeper human experience of wonder at life's complexities.
Schatz demonstrates that the true poetry of science lies not in ignoring its details, but in understanding them—and recognizing that what happens in single-celled organisms or ancient chemical processes ultimately happens in us, too 1 .
| Aspect | Traditional Mechanical View | Schatz's Integrative Approach |
|---|---|---|
| Organisms | Sophisticated machines | Meaning-creating centers with historical depth |
| Evolution | Primarily competitive struggle | Complex interplay of competition, cooperation, and historical accident |
| Metabolism | Biochemical pathways | Layered historical record of Earth's changing environment |
| Humanity's Place | Separate from nature | Connected to all life through shared biological heritage |
A Matter of Wonder succeeds not by providing exhaustive detail on any single topic, but by offering provocative glimpses into biology's most compelling mysteries .
Through Schatz's interdisciplinary lens, we come to see that our very bodies are living records of Earth's history—carrying within us the chemical legacies of ancient oceans, dependent on bacteria for brain function, and governed by cellular powerhouses with their own genetic agendas.
Understanding that our need for vitamin B12 connects us to primordial seas transforms our perspective on daily existence.
Biology doesn't diminish wonder but deepens it, revealing the poetry in scientific details and connections.
In an age of increasing specialization, Schatz's work stands as a testament to the power of interdisciplinary thinking, connecting biochemistry to philosophy, music to genetics, and ultimately, connecting us more deeply to the living world of which we are a part.
