5,500 Years Ago, Something Was Killing Humans in Prehistoric Siberia -- New Research Has Finally Revealed This Ancient Assassin

A longstanding archaeological mystery has loomed over discoveries at ancient burial sites in eastern Siberia: why were so many children and adolescents among the dead?

Now, according to a recent study in the journal Nature, DNA recovered from human remains found in burial sites at four cemeteries near Lake Baikal in eastern Siberia may finally reveal the answer.

Thousands of years ago, prior to the rise of ancient medieval cities -- and their often-rat-infested streets -- a disease famously associated with these rodents had already ravaged communities of prehistoric hunter-gatherers.

The research, based on reconstructions of ancient bacterial genomes preserved in the teeth of these ancient Siberians, revealed the presence of previously unknown strains of Yersinia pestis -- the bacteria responsible for plague -- providing fresh evidence that the lethal disease was already manifesting and killing human populations at least as far back as 5,500 years ago.

It has been postulated that The Bubonic Plague actually came from China...............Some things never change........

Hopefully the Wuhan lab isn’t storing samples.

a long time ago, I was absolute;l fascinated with Siberia and that lake. forget why.

Now I’m interested again.

siberians have shamans, I think, sort of the big daddies of the tribes,, allegedly magical powers. after I eat dinner, which is coming up soon, I’ll give it some thought.

"Shut up, you American! You always talk, you Americans. You talk and you talk and you say, "Let me tell you something" and "I just wanna say this". Well, you're dead now, so shut up!"

Its 2500 BC, your and all the clans have killed off the Mammoths, and you are hungry and have to eat. Your clan turns to the flea infested local rats and Marmots! You become Sick. You Die! (Yes, it is sad for the young girl!)

As the author notes:"Seeing as PD's can carry the plague you may want to substitute with your other favorite meat!"

( We are Fortunate to have science that has demonstrated that there are some animals people should not really use as food, or as pets! )

Even Siberia goes through the motions

did I really say hat? ? You’re really quick. LMAO

Should’ve had the lasagna.😏

I read that one variety of plague bacillus has a semi-symbiotic relationship with Siberian Marmots. It can live in them without killing them and secretes an anti-inflammatory hormone that prevents the marmot's immune system from reacting.

When it gets into humans, it goes wild and the human body's immune system is partly defeated by the same hormones. Basically you feel somewhat ill and then keel over dead a day or two later.

Humans live long enough for Mongol couriers to spread the disease far and wide.

Huh... Whodda thunk Siberian Mouses would be man’s demise?...
