coronavirus where we have Alpha, Delta, Omicron all coming from this strain in Wuhan," says Johannes Krause, a palaeogeneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who co-led the study, published in Nature.
Several years ago, Philip Slavin, an economic and environmental historian at the University of Stirling, UK, and a co-lead author of the study, suggested the disease's emergence might be linked to an unusual surge of deaths in a town in Central Asia in 1338-1339.
The cemeteries, known as Kara-Djigach and Burana, held an unusually high number of tombstones dated to 1338 and 1339, ten of which made explicit reference to a pestilence. “When you have one or two years with excess mortality, it means something funny is going on there," Slavin had said.
