Ancient DNA Rewrites the history of Syphilis
Table of Contents
For centuries, the origins of syphilis, a devastating sexually transmitted infection, have remained shrouded in mystery. The disease’s sudden and widespread impact on Europe in the late 15th century sparked intense debate: did it originate in the Americas, or was it already present in Europe before columbus’s voyages? A landmark study published in nature offers compelling new evidence, considerably shifting our understanding of this historical scourge.
The first documented syphilis outbreak ravaged Europe following King Charles VIII of France’s 1494 invasion of Naples. The disease, characterized by its disfiguring symptoms and high mortality rate, quickly spread across the continent. Interestingly, it was initially known by various names, such as the “French disease” in Italy and the “Neapolitan disease” in France – a testament to the historical tendency to blame neighboring countries for outbreaks.
The timing of the epidemic, shortly after Columbus’s return from the Americas, fueled the “Columbian hypothesis,” suggesting syphilis originated in the Americas and was introduced to Europe through transatlantic contact. Though,a competing theory proposed that the disease existed in Europe prior to the 15th century,only becoming more virulent during that period.
This new research, spearheaded by Kirsten bos and Johannes Krause of the Max Planck Institute for Evolutionary Anthropology, provides a powerful counterpoint. The team analyzed ancient DNA from skeletal remains unearthed in Mexico, Peru, Argentina, and Chile. Employing cutting-edge paleopathology techniques, they successfully reconstructed five genomes of Treponema pallidum, the bacterium responsible for syphilis and its related diseases, yaws and bejel. Remarkably, these genomes date back as far as 9,000 years, long before Columbus’s voyages.
This revelation strongly supports the hypothesis that syphilis and related treponematoses have ancient roots in the Americas. The study’s findings challenge long-held assumptions and offer a revised understanding of the disease’s global spread, highlighting the importance of interdisciplinary research in unraveling complex historical and medical mysteries.
Ancient DNA Rewrites the History of Syphilis
A groundbreaking study published by the Max Planck Institute for the science of Human History has overturned long-held beliefs about the origin of syphilis. Using advanced genomic analysis of ancient DNA, researchers have definitively traced the disease back to the Americas, centuries before its appearance in Europe.
“we’ve known for some time that syphilis-like infections occurred in the Americas for millennia, but from the lesions alone, it’s impractical to fully characterize the disease,” explained Casey Kirkpatrick, a postdoctoral researcher at the Max Planck Institute. the genomic analysis revealed that Treponema pallidum, the bacterium responsible for syphilis, originated in the americas during the middle Holocene epoch and subsequently diversified into the subspecies causing treponemal diseases today.
Dr. Kirsten Bos, a key researcher on the project, stated: “The data clearly support a root in the Americas for syphilis and its known relatives. Their introduction to Europe, which started in the late 15th century, is most consistent with the evidence.” The study suggests the global spread of syphilis was significantly accelerated by the transatlantic slave trade and European colonial expansion.
While the study provides strong evidence for an American origin,it doesn’t entirely resolve all historical debates. Skeletal remains in europe showing syphilis-like lesions predating 1492 challenge the commonly held “Columbian Exchange” theory. “The search will continue to define these earlier forms, and ancient DNA will surely be a valuable resource,” said Johannes krause, co-author of the study. He added, “Who knows what older related diseases made it around the world in humans or other animals before the syphilis family appeared.”
This research highlights the profound interconnectedness of human history and disease. Indigenous populations in the Americas lived with early forms of syphilis and related diseases long before European contact.“While indigenous american groups harbored early forms of these diseases, Europeans were instrumental in spreading them around the world,” Bos remarked. The devastating impact of European expansion extended beyond syphilis; it introduced entirely new diseases, such as smallpox, which decimated indigenous communities.
The study’s findings are a meaningful contribution to our understanding of global health history and the lasting consequences of colonialism. The research underscores the importance of continued inquiry into ancient DNA to further illuminate the complex history of human disease.

Ancient DNA Uncovers Deep History of Treponemal Disease in the Americas
A groundbreaking study published in Nature has rewritten our understanding of treponemal diseases in the Americas. Researchers analyzed ancient genomes, revealing a far more complex and ancient history than previously imagined. The findings challenge long-held beliefs about the origin and spread of these diseases, which include yaws, syphilis, and bejel.
The research team, led by Dr. Roberto Barquera, meticulously examined ancient DNA samples from across the Americas. Their analysis uncovered evidence of treponemal infections dating back centuries, significantly predating the arrival of Europeans. “This research fundamentally alters our understanding of the timeline and geographic distribution of these diseases,” stated Dr.Barquera. “We found evidence suggesting a much longer and more nuanced history than previously thought possible.”
The study’s findings have significant implications for our understanding of public health and disease evolution. The researchers identified distinct genetic lineages of treponemes, suggesting that different strains existed in the Americas long before contact with the Old World. this challenges the customary narrative that syphilis originated in the old World and was introduced to the Americas during the Columbian Exchange.
“This research fundamentally alters our understanding of the timeline and geographic distribution of these diseases,” stated Dr. Barquera. “We found evidence suggesting a much longer and more nuanced history than previously thought possible.”
While the study doesn’t definitively pinpoint the origin of syphilis, it strongly suggests that the disease’s history in the Americas is far more intricate than previously believed. the researchers emphasize the need for further research to fully understand the evolutionary relationships between different treponemal strains and their impact on ancient populations.
The implications of this research extend beyond academic circles.Understanding the ancient history of treponemal diseases can inform current public health strategies for managing and preventing these infections, which remain a significant global health concern. The study highlights the importance of interdisciplinary research,combining genetic analysis with archaeological and historical data,to unravel complex medical mysteries.

A New Look at an Old Mystery:
For centuries, the origins of syphilis have been shrouded in mystery and misinformation. Theories blamed everything from historical conquests to divine punishment. One prevailing theory, known as the “Columbian hypothesis,” proposed that syphilis was introduced to Europe from the Americas by Christopher Columbus and his crew in the late 15th century.
The Power of Ancient DNA:
Now, a groundbreaking study from the Max Planck Institute for the Science of Human History is shedding new light on syphilis’s history. Using cutting-edge techniques, researchers analyzed ancient DNA extracted from skeletal remains found in various sites across the Americas.This DNA analysis allowed them to reconstruct ancient genomes of Treponema pallidum, the bacterium responsible for syphilis.
Tracing Syphilis to the Americas:
The study’s findings are conclusive: the earliest known strains of T. pallidum date back as far as 9,000 years ago in the Americas. This discovery pre-dates Columbus’s voyages by thousands of years,definitively proving syphilis originated in the Americas.
