The research group analyzed the ancient DNA extracted from 50,000 years old sedimentary feces (the oldest sample of fecal material available to date). The samples were collected in El Salt (Spain), a site where many Neanderthals lived.

Interesting...but I do wonder how (after 50000 years) fecal matter could remain preserved and identifiable as such.
Where's the guy always squawking about the firearm write ups when you need him for the 50000 year old poop articles?
How would one recognize 50,000 year-old poop?
Hey, Dad, I using that degree you paid for to play with poop.
Guessing Neanderthals didn’t have Cheetos when they got the munchies.
I am doing a time capsule and will include a “sample” now that I realize the importance.
I can’t fathom any more enthralling subject than Neanderthal poo!
Easy. By it's smell.
Fossilized crap is called coprolite and is just as distinctive as when in was deposited;
Or even how it could be (fraudulently) elected as president.
From the article:
“The gut microbiota is the collection of trillions of symbiont micro-organisms that populate our gastrointestinal tract. It represents an essential component of our biology and carries out important functions in our bodies, such as regulating our metabolism and immune system and protecting us from pathogenic micro-organisms.
“Recent studies have shown how some features of modernity - such as the consumption of processed food, drug use, life in hyper-sanitized environments - lead to a critical reduction of biodiversity in the gut microbiota. This depletion is mainly due to the loss of a set of microorganisms referred to as “old friends.”
“The process of depletion of the gut microbiota in modern western urban populations could represent a significant wake-up call,” says Simone Rampelli, who is a researcher at the University of Bologna and first author of the study. “This depletion process would become particularly alarming if it involved the loss of those microbiota components that are crucial to our physiology.”
“Indeed, there are some alarming signs. For example, in the West, we are witnessing a dramatic increase in cases of chronic inflammatory diseases, such as inflammatory bowel disease, metabolic syndrome, type 2 diabetes, and colorectal cancer.
“The research group analyzed ancient DNA samples collected in El Salt (Spain), a site where many Neanderthals lived. To be more precise, they analyzed the ancient DNA extracted from 50,000 years old sedimentary feces (the oldest sample of fecal material available to date). In this way, they managed to piece together the composition of the micro-organisms populating the intestine of Neanderthals. By comparing the composition of the Neanderthals’ microbiota to ours, many similarities aroused.
“Through the analysis of ancient DNA, we were able to isolate a core of microorganisms shared with modern Homo sapiens,” explains Silvia Turroni, researcher at the University of Bologna and first author of the study. “This finding allows us to state that these ancient micro-organisms populated the intestine of our species before the separation between Sapiens and Neanderthals, which occurred about 700,000 years ago.”
No way. Too many volatile compounds that would have outgassed over the centuries. 50,000 year old droppings would be totally inert and recognized only by visual inspection. Change my mind.
some people just can’t leave sh*t alone...
They probably stepped in it 😆
Scientists can’t even spellz, should be crapolite, sheesh!
We have the entire physical genome for Neanderthals.
It was recovered almost completely from fossilized teeth that are roughly the same age.
The poop is fossilized, just like the teeth.
Capsules of the full Neanderthaler gut biota will soon be available at your local health food store...
Twinkies. That is all.
Years ago I bought some dinosaur coprolite while in Arizona for my kids. They enjoyed playing with it more than with regular rocks. Poop millions of years old can be fun; can't be said about fresh poop.
"The assortments of bacteria that live within the intestines of isolated tribes are far more diverse than the microbes found in the guts of Americans."
A program and a place to store/warehouse the diversity of gut bacteria in the world has been started.

Well....here it is, I found it:
