5,500-Year-Old Colombian Fossil Challenges Syphilis Origin Timeline

A 5,500-year-old human fossil unearthed in Colombia is prompting scientists to reconsider the established timeline for the origin of syphilis. This ancient specimen suggests that the disease may have existed far earlier than previously believed, challenging the long-held theory that syphilis primarily emerged after the European exploration of the Americas.

The ancient bone lesion found on the fossil provides crucial evidence for paleopathologists. Researchers are now meticulously examining these signs of ancient infection to understand the evolutionary path of the causative agent, Treponema pallidum, and its long-standing relationship with human populations. This groundbreaking discovery could fundamentally alter our understanding of infectious disease history.
