모여 살기 시작한 순간, 죽음도 모이기 시작했습니다

#PrehistoricEra #Epidemic #Humanity'sFirstPandemic During the hunter-gatherer era, germs were simply there. However, in a world where groups of twenty people lived scattered, infectious diseases could not spread. The moment humanity began to live together in one place 10,000 years ago, everything changed. People gathered, livestock gathered, and germs gathered as well. In 2025, a research team from Harvard University discovered the plague bacterium for the first time in prehistoric sheep, and in the same year, a joint study by the University of Copenhagen and Cambridge revealed that zoonotic infections increased explosively starting around 5,000 years ago. In a 5,000-year-old passageway tomb in Sweden, evidence was found that a single family suffered from the same infectious disease three times across six generations. During this period, the European population declined by 20–60%, and Triphylia (Europe's first city-level settlement) vanished entirely. What is surprising is that traces of this infectious disease still remain in our DNA. The formula for pandemics leading up to COVID-19 remains the same now as it was thousands of years ago. ⚠ This video was produced for educational and informational purposes.
