Estimating survival probability using the terrestrial extinction history for the search for extraterrestrial life. [PDF]
Sci Rep, 2020 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.
