Syphilis, the infamous sexually transmitted disease that has plagued humanity for centuries, may have a far more ancient origin than previously thought. A 5,500-year-old fossil from Colombia has shed new light on the evolutionary history of Treponema pallidum, the bacterium responsible for syphilis.
According to researchers at Southern Methodist University, the discovery of an ancient Treponema pallidum genome in a human skeleton excavated from a rock shelter in Colombia suggests that pathogens causing treponemal diseases like syphilis, bejel, or yaws are several millennia older than we thought. This finding challenges our traditional understanding of syphilis' origins and could lead to a reevaluation of the "Columbian" theory.
The story of syphilis began in Europe around 1495, when King Charles VIII of France occupied Naples, sparking a massive outbreak that would go on to claim up to 5 million lives. For centuries, the siege of Naples was considered the first recorded case of syphilis, but researchers now believe this event may have been just one part of a much larger and more complex relationship between humans and Treponema pathogens.
According to Elizabeth Nelson, an anthropologist at Southern Methodist University, the evolutionary history of Treponema pallidum stretches back at least 13,700 years. The discovery suggests that the bacterium was already diverse and capable of infecting people by then, with various subspecies spreading globally with early human migrations out of Africa.
However, much remains to be learned about syphilis' origins before we can say for certain how it evolved, spread, or mutated over time. Researchers hope to explore these questions by analyzing other ancient pathogen genomes from different parts of the world and social contexts, such as hunter-gatherers, farmers, and city dwellers.
In conclusion, the discovery of an ancient Treponema pallidum genome in Colombia has opened up new avenues for research into syphilis' origins. By examining the evolutionary history of this bacterium and its interactions with humans, researchers may uncover a more nuanced and complex understanding of how syphilis emerged and spread across the globe.

i mean we already knew that our ancestors were super messy and stuff but to think that we might've been dealing with this gross bacteria for 13k years is wild. and now they're saying it could've spread with people migrating outta Africa which is like half of humanity so yeah that makes sense. but still can't believe it's gonna be all over the news, gotta tune in tomorrow to see what else comes out 
I gotta think about this for a sec... If we're talking 5,500 years old, that's wild 
. It makes you wonder if our ancestors were already dealing with these kinds of diseases back in the day. Like, how did they even know how to fight them off? 
And it's crazy to think about all those people dying from syphilis back in the 1500s... 5 million lives? That's a lot 
. I'm just glad that we've made some progress in understanding and treating these diseases now 
. We should keep studying this stuff to learn more about how our bodies interact with pathogens 
. Maybe one day we'll find a cure or something 
. This finding makes sense, especially considering how fast pathogens can spread when humans are in close proximity. Still, it's a bit mind-blowing to think that our understanding of syphilis has been skewed for so long 
. Now we're talking about 5,500-year-old fossils and ancient genomes... this is some next-level stuff 
. It makes sense that it's more ancient than we thought, considering how fast diseases can spread when humans start moving around and interacting with each other. This discovery is gonna be super interesting to learn about - what else do they think they might find out from analyzing those old pathogen genomes?
...i wonder what other secrets are hidden in the fossil record, waiting to be uncovered 
...this discovery is like a key turning in a lock, unlocking new questions and possibilities about our shared human experience 
This discovery is giving me major goosebumps!
. It's going to be a wild ride exploring the ancient history of syphilis 
.
. Seriously though, this just proves that our ancestors were way more messed up than we think. 5,500 years old? That's like ancient times, fam! 
And now we're trying to figure out how syphilis spread across the globe? Like, good luck with that. They should just be happy they didn't have TikTok back then 
. The fact that it was already diverse and spreading globally with human migrations makes total sense. And now researchers are gonna dig into other ancient pathogen genomes to learn more 
That's wild and honestly kinda creepy 
. What else have we been lied to about? I mean, I always knew this stuff was gonna be way more complex than what we learn in school... but 5,500 years old is just crazy talk 
. We need more research ASAP!
5,500 years old? That's even older than my fave brand's existence 
And now we know that it was already spreading globally over 13,700 years ago? 
. And btw, my fave brand has been around for even longer than this 
.
.
that's crazy! i mean, who knew ancient humans were already dealing with treponema pathogens?
