A fascinating ethnography of microbes that opens up new spaces for anthropological inquiry

 

The trillions of microbes in and on our bodies are determined by not only biology but also our social connections. Gut Anthro tells the fascinating story of how a sociocultural anthropologist developed a collaborative “anthropology of microbes” with a human microbial ecologist to address global health crises across disciplines. It asks: what would it mean for anthropology to act with science? Based partly at a preeminent U.S. lab studying the human microbiome, the Center for Genome Sciences at Washington University, and partly at a field site in Bangladesh studying infant malnutrition, it examines how microbes travel between human guts in the “field” and in microbiome laboratories, influencing definitions of health and disease, and how the microbiome can change our views on evolution, agency, and life.

As lab scientists studied the interrelationships between gut microbes and malnutrition in resource-poor countries, Amber Benezra explored ways to reconcile the scale and speed differences between the lab, the intimate biosocial practices of Bangladeshi mothers and their children, and the looming structural violence of poverty. In vital ways, Gut Anthro is about what it means to collaborate—with mothers, local field researchers in Bangladesh, massive philanthropic global health organizations, with the microbiome scientists, and, of course, with microbes. It follows microbes through various enactments in scientific research—microbes as kin, as data, and as race. Revealing how racial categories are used in microbiome research, Benezra argues that microbial differences need transdisciplinary collaboration to address racial health disparities without reifying race as a straightforward biological or social designation.

Gut Anthro is a tour de force of science studies and medical anthropology as well as an intensely personal and deeply theoretical accounting of what it means to do anthropology today.

At the close of the 1970s, the two-domain classification scheme long used by most biologists—prokaryotes versus eukaryotes—was upended by the discovery of an entirely new group of organisms: archaea. Initially thought to be bacteria, these single-celled microbes—many of which were first found in seemingly unlivable habitats like the volcanic hot springs of Yellowstone National Park—were in fact so different at molecular and genetic levels as to constitute a separate, third domain beside bacteria and eukaryotes. Their discovery sparked a conceptual revolution in our understanding of the evolution of life, and Patrick Forterre was—and still is—at the vanguard of this revolution.

In Microbes from Hell, one of the world’s leading experts on archaea and hyperthermophiles, or organisms that have evolved to flourish in extreme temperatures, offers a colorful, engaging account of this taxonomic upheaval. Blending tales of his own search for thermophiles with discussions of both the physiological challenges thermophiles face and the unique adaptations they have evolved to live in high-temperature environments, Forterre illuminates our developing understanding of the relationship between archaea and the rest of Earth’s organisms. From biotech applications to the latest discoveries in thermophile research, from microbiomes to the communities of organisms that dwell on deep-sea vents, Forterre’s exploration of life-forms that seem to thrive at the mouth of hell provides a glimpse into the early days of Earth, offering deep insight into what life may have looked like in the extreme environments of our planet’s dawn.

We live in a time of unprecedented scientific knowledge about the origins of life on Earth. But if we want to grasp the big picture, we have to start small—very small. That’s because the real heroes of the story of life on Earth are microbes, the tiny living organisms we cannot see with the naked eye. Microbes were Earth’s first lifeforms, early anaerobic inhabitants that created the air we breathe. Today they live, invisible and seemingly invincible, in every corner of the planet, from Yellowstone’s scalding hot springs to Antarctic mountaintops to inside our very bodies—more than a hundred trillion of them. Don’t be alarmed though: many microbes are allies in achieving our—to say nothing of our planet’s—health.
           
In Planet of Microbes, Ted Anton takes readers through the most recent discoveries about microbes, revealing their unexpected potential to reshape the future of the planet. For years, we knew little about these invisible invaders, considering them as little more than our enemies in our fight against infectious disease. But the more we learn about microbes, the more it’s become clear that our very lives depend on them. They may also hold the answers to some of science’s most pressing problems, including how to combat a warming planet, clean up the environment, and help the body fight off a wide variety of diseases. Anton has spent years interviewing and working with the determined scientists who hope to harness the work of microbes, and he breaks down the science while also sharing incredible behind-the-scenes stories of the research taking place everywhere from microbreweries to Mars.
           
The world’s tiniest organisms were here more than three billion years before us. We live in their world, and Planet of Microbes at last gives these unsung heroes the recognition they deserve.
