CATASTROPHE and Earth's Evolution: When Bad Things Happen to Good Planets

June 10 & 11

Life on Earth has evolved as a consequence of the evolution of Earth itself. The Earth of the present is clearly not the same planet that it was when it first formed, but its metamorphosis into the habitable environment we enjoy today was not always gradual and benign. Several catastrophic events have occurred that have served both as opportunity and threat. In this talk we will look at a series of cataclysmic events that have shaped the Earth we know and love, and we will speculate about what may lie ahead.
