It's interesting to see how many mass extinctions we might go through in the coming millions of years: a few super novae, asteroid strikes, etc. This reminds me of the earlier thread on the Fermi Paradox. Does anyone know if the paradox discussions take into account the seemingly relative frequency of mass extinctions? As far as I understand, the Drake Equation does not. Maybe it's the case that intelligent life on Earth forms against all odds due to a relatively (and improbably) quiet ~75M years?
