Fossilized feces from Mexico's ancient 'Cave of the Dead Children' have provided a unique glimpse into the intestinal parasites and diet of people living over 1,000 years ago. The findings suggest that intestinal infections such as pinworm and Shigella were common among the Loma San Gabriel people who inhabited the cave around 1,200 to 1,400 years ago.
The study used a new technique called qPCR to analyze DNA from 10 of these ancient fecal samples, which is more targeted than traditional DNA sequencing. The analysis revealed the genetic signatures of various gut parasites, including Blastocystis and multiple strains of E. coli, as well as pinworms in the majority of samples.
The discovery was surprising given that the DNA from these pathogens had been expected to degrade over time, and it highlights the potential for modern molecular methods to inform studies of the past. The study's authors believe that this technique could be used to analyze other ancient fecal samples, potentially revealing new insights into the health and living conditions of our ancestors.
The Cave of the Dead Children, also known as La Cueva de Los Muertos Chiquitos, is a site in northern Mexico where archaeologists have uncovered over 500 ancient desiccated fecal samples and more than a dozen skeletons of children who died under mysterious circumstances. The cave's dry climate has helped preserve these ancient samples for thousands of years.
The study's findings offer a fascinating glimpse into the lives of people living in the past, highlighting the challenges they faced with regards to health and sanitation. While the study was limited to 10 samples, it provides a proof-of-concept for using qPCR to identify intestinal parasites in ancient feces, which could be applied to larger studies in the future.

. Can you believe that ancient poop is giving us clues about what people ate and how they lived over 1k years ago? It's wild! I mean, we always think of our own poop as private, but it seems like scientists are just happy to get their hands on some old feces and analyze them 
. The fact that the DNA didn't degrade like expected is crazy, and now they're hoping to use this technique to study other ancient samples. That's just mind-blowing!
. I'm not saying they had it worse or better, but it's wild to see that some things never change, right? 
. If we can learn from the past and figure out ways to prevent these kinds of intestinal infections, maybe we can make a real difference in people's lives today 
.
. If scientists can use this method to analyze ancient samples and learn more about our ancestors, we might just uncover some new insights into how to tackle health issues in the future 
.
I mean, can you imagine living without antibiotics and antiparasitic meds? It's crazy to think that our ancestors were dealing with all these gut issues and still managed to thrive. The fact that they were able to survive for so long is a testament to their resilience, but also highlights the importance of having access to proper healthcare. I guess it's a reminder that we're not as evolved as we think we are 
. It's like, what can we take away from this? That even back then, people were dealing with the same kind of issues as us? I mean, it's not exactly reassuring, but it's also kinda humbling 
. We're not so different, you know? And on a bigger scale, this whole thing just highlights how little we actually know about our own biology and health 
. but seriously, this study shows how far we've come with technology & science. it's mind-blowing that they were able to extract DNA from something thats been around for so long
