But what we’re really after with this study is we’re trying to understand the evolution of the gut microbiome. We know that the communities of bacteria that live in our gut are highly responsive to the diets that we eat. And we know that industrialized diets have really changed the way that our microbial communities are structured. When I was growing up in suburban Chicago in the 1950s, after Sunday afternoon dinners that often centered on rare roast beef, my parents would take all four children on car rides into the countryside. We were grossed out by the smells of the dairy farms and incredulous that, as my father was happy to insist, our delicious dinner could have come from those animals. We had a mantra for the moment we got the first whiff: “Red meat from a cow? Pee-YOO!”

So overall, while the Cloaca Massima solved Rome’s sewage removal problems, it didn’t solve the city’s health issues. It carried the filth out of the city and dumped it into the Tiber, polluting the very water some citizens depended on for irrigation, bathing, and drinking. And so, while the Romans no longer had to see, or smell, their excrement, they hadn’t done much to eliminate its hazardous nature. Through the next several centuries, as humankind kept concentrating in cities, it would find itself in a bitter battle with its own waste, seemingly with no way to win.

The youngest ones that we looked at are actually just a few centuries old and come from Surrey, England.

Title: CoproID predicts the source of coprolites and paleofeces using microbiome composition and host DNA content The Harappans and the Minoans were probably the first people who really flushed, albeit without metal levers attached to gleaming white bowls. This approach worked for twenty-something-thousand inhabitants pooping on some 300 acres, but cities were going to grow much bigger than that. The Romans and the Cloaca MassimaChristina Warinner, assistant professor of anthropology at Harvard University in Cambridge, Massachusetts, joins Science Friday producer Kathleen Davis to talk coprolites, and what ancient feces can tell us about our ancestors, and ourselves. These mutations are in Europe, parts of the near east, and parts of East Africa. And so these populations are called lactase persistent. And they’re milk tolerant. But what’s really interesting is that we see that while these societies in these areas have long practiced dairy production, we also see that other populations, for example, in Mongolia, also have very long histories of dairying. CHRISTINA WARINNER: So that is the focus of a study that we’re still doing. I mean, we found some basic information. So, for example, from the human feces, we’re able to reconstruct aspects of information about those individuals. We could tell if they were male or female. We could reconstruct their ancestry profile and show that it matched the region of the world that they came from. Uses humour and science to discuss its evolutionary, ecological and cultural perspectives. He shines a light on a subject many people would rather not think about, thank you very much.” — The Record

CHRISTINA WARINNER: Well, it really depends on the preservation. So sometimes, they actually resemble turds, and they’re very visibly recognizable. Other times, they’ve been really squashed and flattened by the sediments around them. And so you can look at them visually and often identify them as coprolites. They have a different texture and consistency than the soil around them. CHRISTINA WARINNER: Exactly. They almost always come from some sort of context that’s extremely dry or frozen. So places like dry caves in the American southwest or in northern Mexico, or salty deposits in mountainous areas. Those are typically where we find coprolites. Foricae remains may look beautiful and clean to us today, but that was hardly the case when these facilities were operational.

So we took it to a second level and we looked at the microbial communities as well. And the microbial communities within the human gut microbiome and the dog gut microbiome, although similar in many ways, are distinct. And so we were able to use these two different lines of evidence to distinguish them. The appearance of human fecal matter varies according to diet and health. [11] Normally it is semisolid, with a mucus coating. A combination of bile and bilirubin, which comes from dead red blood cells, gives feces the typical brown color. [1] [2]

Elephants, hippos, koalas and pandas are born with sterile intestines, and require bacteria obtained from eating the feces of their mothers to digest vegetation. And in many ways, these changes are associated with health consequences and chronic inflammation. So the big question we wanted to ask was, historically or pre-historically, when did these changes start to happen? Is it really associated with industrialization? Or might it begin earlier with more intensive agriculture, or maybe with the beginnings of agriculture? These ancient poops are called coprolites, and they’re quite rare. Despite their less-than-glamorous-origins, each one is a gold mine of information about who left it behind. That’s because fecal fossils are a snapshot of the microbiome from which they came. Some researchers say studying these ancient records of diet and bacteria could help us learn about modern problems such as lactose intolerance and gut inflammation.

One unexpected finding of our study is the realization that the archaeological record is full of dog poop,” says Professor Christina Warinner, senior author of the study. But Warinner also expects coproID to have broader applications, especially in the fields of forensics, ecology, and microbiome sciences.
