This seafood contains "old carbon" from deep, upwelling ocean waters.As such, they might fall prey to the so-called "marine reservoir effect" that can throw off radiocarbon dating of a skeleton by hundreds or even thousands of years.Upon successful registration we will email you a confirmation with the event details.For questions about the Event email Heidi, your Columbus Pre-Dating Speed Dating Coordinator or to register by phone call 614-653-7053.They found most of the skeletal material didn't actually meet at least one of the standard diagnostic criteria for chronic syphilis, such as pitting on the skull, known as , and pitting and swelling of the long bones."There's no really good evidence of a syphilis case before 1492 in Europe," Armelagos told Live Science. The 16 reports that did meet the criteria for syphilis came from coastal regions where seafood was a large part of the diet.It then proceeded to devastate Europe, said researcher George Armelagos, a skeletal biologist at Emory University in Atlanta."Syphilis has been around for 500 years," said researcher Molly Zuckerman at Mississippi State University.
New skeletal evidence suggests Columbus and his crew not only introduced the Old World to the New World, but brought back syphilis as well, researchers say."In 1492, you had the transmission of a number of diseases from Europe that decimated Native Americans, and you also had disease from Native Americans to Europe." "The lesson we can learn for today from history is that these epidemics are the result of unrest," Armelagos added."With syphilis, wars were going on in Europe at the time, and all the turmoil set the stage for the disease.These seemed to be evidence that syphilis originated in the Old World and that Columbus was not to blame.
Armelagos and his colleagues took a closer look at all the data from these prior reports.
"Once we adjusted for the marine signature, all of the skeletons that showed definite signs of treponemal disease appeared to be dated to after Columbus returned to Europe," Harper said, findings detailed in the current Yearbook of Physical Anthropology.
