Dr. Shamam Waldman discusses a recent paper she co-authored with her colleagues at the Hebrew University of Jerusalem that was published in the journal Cell. The study was an effort to sequence the DNA from the remains of Ashkenazi Jews in medieval Europe and focused on a DNA analysis that was done on the extracted teeth of individuals who were buried in a Jewish cemetery in Erfurt, Germany around the 14th century. The findings of the study shed light on where Ashkenazi Jews originated from, how the communities formed, and common genetic traits they shared with modern populations.
