Goats and Soda How Bubonic Plague Reshaped The Streets Of Mumbaiīlack Death, a kind of bubonic plague, is one of several strains of plague. What's more, the researchers find that the strain from this region "gave rise to the majority of strains circulating in the world today," says Phil Slavin, co-author on the paper and a historian at the University of Stirling in Scotland. New research, published this month in the journal Nature, provides biological evidence that places the ancestral origins of Black Death in Central Asia, in what is now modern-day Kyrgyzstan. Now, researchers say they've found the genetic ancestor of the Black Death, which still infects thousands of people each year. Where did the Black Death come from? And when did it first appear?Īs the deadliest pandemic in recorded history – it killed an estimated 50 million people in Europe and the Mediterranean between 13 - it's a question that has plagued scientists and historians for nearly 700 years. ![]() Pictures from History/Universal Images Group /Getty Images Scientists say they may have found the origin of this deadly disease. A woodcut from the 15th century depicts a scene from the Black Death plague, which killed an estimated 50 million people in Europe and the Mediterranean between 13.
