Title: Animal Diseases Leapt To Humans When We Started Keeping Livestock

Link: https://science.slashdot.org/story/25/07/09/1...

Researchers analyzing DNA from 1,313 ancient humans across Eurasia found that
zoonotic pathogens first appeared in human populations around 6,500 years
ago, coinciding with the transition from hunter-gatherer societies to
livestock farming. The genomic study, published in Nature, identified 5,486
DNA sequences from bacteria, viruses and parasites in blood remnants from
bones and teeth spanning 37,000 years. Zoonotic pathogens were detected only
in remains 6,500 years old or younger, peaking around 5,000 years ago when
pastoralist communities from the Steppe region migrated into Europe with
large herds. The plague bacterium Yersinia pestis first appears in the
dataset between 5,700-5,300 years ago.
