Query: Estimating survival probability using the terrestrial extinction history
  for the search for extraterrestrial life   Several exoplanets have been discovered to date, and the next step is the
search for extraterrestrial life. However, it is difficult to estimate the
number of life-bearing exoplanets because our only template is based on life on
Earth. In this paper, a new approach is introduced to estimate the probability
that life on Earth has survived from birth to the present based on its
terrestrial extinction history. A histogram of the extinction intensity during
the Phanerozoic Eon is modeled effectively with a log-normal function,
supporting the idea that terrestrial extinction is a random multiplicative
process. Assuming that the fitted function is a probability density function of
extinction intensity per unit time, the estimated survival probability of life
on Earth is ~0.15 from the beginning of life to the present. This value can be
a constraint on $f_i$ in the Drake equation, which contributes to estimating
the number of life-bearing exoplanets.
