This disagreement highlights significant challenges in definitively determining the virus's source.

What evidence conclusively demonstrates the American origin of syphilis, challenging previous theories?

A study published in Nature suggests that syphilis originated in the Americas, predating Columbus's voyages. Researchers reconstructed five ancient genomes from pre-Columbian skeletal remains across the Americas, showing similarities to modern syphilis strains. This finding challenges the long-held belief that the disease was brought to Europe from the Americas.
