Victor Gostin explores the effect of major earth impacts on human history.
About the Presentation
Earth’s encounters with comets has led to megafaunal extinctions and collapse of Chinese dynasties. Throughout history, comets have been seen as omens of change and disaster in many cultures. The legends of St Michael, feathered serpents, and celestial dragons are some examples of these encounters. A major cometary impact centred over North America, around 12,900 BP recorded as the Younger Dryas episode created massive wildfires and caused the extinction of numerous large animals like the mammoth (megafauna).
