TED-ED: The past, present and future of the bubonic plague - Sharon N. DeWitte

The Black Death was a devastating epidemic in the 14th century, wiping out a significant portion of the world's population. It was caused by Yersinia pestis, the same bacterium responsible for bubonic plague today. Despite no significant genetic differences between ancient and modern strains, the medieval outbreak was deadlier due to societal factors like malnutrition and poverty. The epidemic led to socioeconomic changes, weakening feudalism and altering the gene pool. Modern antibiotics have reduced the threat, but drug-resistant strains pose new risks. Understanding the Black Death's impact helps prevent future epidemics.

What was the primary bacterium responsible for the Black Death?

• Bacillus anthracis

• Staphylococcus aureus

• Yersinia pestis

• Escherichia coli

Which factor did NOT contribute to the rapid spread of the Black Death in the 14th century?

• Direct person-to-person transmission

• Advanced medical facilities

• Poor living conditions

• High population density

How did the Black Death impact Europe's economy?

• It led to a decrease in food availability.

• It caused a decline in social mobility.

• It resulted in better pay and living conditions for survivors.

• It strengthened the feudal system.

What biological impact did the Black Death have on the surviving population?

• It reduced genetic diversity.

• It increased susceptibility to diseases.

• It left a population with potentially more disease-resistant genes.

• It caused a permanent decline in population numbers.

Why is it important to study the Black Death today?

• To understand medieval architecture

• To prevent future pandemics

• To learn about ancient trade routes

• To study the evolution of language
