>A site in Sweden was the source of the DNA evidence and trade networks were proposed as the likely avenue of spread rather than migrations of populations. There is evidence that suggests Y. pestis may have originated in Europe in the Cucuteni–Trypillia culture, not in Asia as is more commonly believed
>DNA evidence published in 2015 indicates Y. pestis infected humans 5,000 years ago in Bronze Age Eurasia, but genetic changes that made it highly virulent did not occur until about 4,000 years ago. The highly virulent version capable of transmission by fleas through rodents, humans, and other mammals was found in two individuals associated with the Srubnaya culture from the Samara region in Russia from around 3,800 years ago and an Iron Age individual from Kapan, Armenia, from around 2,900 years ago. This indicates that at least two lineages of Y. pestis were circulating during the Bronze Age in Eurasia. The Y. pestis bacterium has a relatively large number of nonfunctioning genes and three "ungainly" plasmids, suggesting an origin less than 20,000 years ago. One such strain has been identified from about 4000 BP (the "LNBA lineage" (Late Neolithic and Bronze Age lineage)) in western Britain, indicating that this highly transmissible form spread from Eurasia to the far north-western edges of Europe
>In 2021, researchers found a 5,000-year-old victim of Y. pestis, the world's oldest-known, in hunter-gatherer remains in the modern Latvian and Estonian border
