The spatiotemporal distribution of human pathogens in ancient Eurasia - Nature

Screening shotgun-sequencing data from ancient humans covering 37,000 years of Eurasian history uncovers the widespread presence of ancient bacterial, viral and parasite DNA and zoonotic pathogens coincide with the widespread domestication of livestock.
